Brazil

The word Brazil probably comes from the Portuguese word for brazilwood, a tree that once grew plentifully along the Brazilian coast. In Portuguese, brazilwood is called pau-brasil, with the word brasil commonly given the etymology 'red like an ember', formed from brasa ('ember') and the suffix -il (from -iculum or -ilium). It has alternatively been suggested that this is a folk etymology for a word for the plant related to an Arabic or Asian word for a red plant. As brazilwood produces a deep red dye, it was highly valued by the European textile industry and was the earliest commercially exploited product from Brazil. Throughout the 16th century, massive amounts of brazilwood were harvested by indigenous peoples (mostly Tupi) along the Brazilian coast, who sold the timber to European traders in return for assorted European consumer goods.

The official Portuguese name of the land, in original Portuguese records, was the 'Land of the Holy Cross' (Terra da Santa Cruz), but European sailors and merchants commonly called it the 'Land of Brazil' (Terra do Brasil) because of the brazilwood trade. Popular usage eclipsed and eventually supplanted the official Portuguese name. Some early sailors called it the 'Land of Parrots'. In the Guarani language, Brazil is called Pindorama, meaning 'land of the palm trees'.

=== Pre-Cabraline era ===

Some of the earliest human remains found in the Americas, Luzia Woman, were found in the area of Pedro Leopoldo, Minas Gerais, and provide evidence of human habitation going back at least 11,000 years. The earliest pottery ever found in the Western Hemisphere was excavated in the Amazon basin of Brazil and radiocarbon dated to over 8,000 years ago (6000 BC). The pottery was found near Santarém and provides evidence that the region supported a complex prehistoric culture. The Marajoara culture flourished on Marajó in the Amazon delta from AD 400 to 1400, developing sophisticated pottery, social stratification, large populations, mound building, and complex social formations such as chiefdoms.

Around the time of the Portuguese arrival, the territory of present day Brazil had an estimated Indigenous population of 7 million people, mostly semi-nomadic, who subsisted on hunting, fishing, gathering, and migrant agriculture. The population comprised several large Indigenous ethnic groups (e.g., the Tupis, Guaranis, and Gês. The Tupi people were subdivided into the Tupiniquins and Tupinambás.

Before the arrival of the Europeans, the boundaries between these groups and their subgroups were marked by wars that arose from differences in culture, language and moral beliefs. These wars also involved large-scale military actions on land and water, with cannibalistic rituals on prisoners of war. While heredity had some weight, leadership was a status more won over time than assigned in succession ceremonies and conventions. Slavery among the Indigenous groups had a different meaning than it had for Europeans, since it originated from a diverse socioeconomic organization, in which asymmetries were translated into kinship relations.

Following the 1494 Treaty of Tordesillas, the land now called Brazil was claimed for the Portuguese Empire on 22 April 1500, with the arrival of the Portuguese fleet commanded by Pedro Álvares Cabral. Along the coast, the Portuguese encountered various Indigenous communities, most of whom spoke languages of the Tupi–Guarani family. Though the first settlement, São Vicente, was founded in 1532, colonization effectively began in 1534, when King John III of Portugal divided the territory into the fifteen private and autonomous captaincies.

However, the decentralized and unorganized captaincy system proved unsuccessful, and in 1549 the Portuguese king restructured them into the Governorate General of Brazil in the city of Salvador, which became the capital of a single and centralized Portuguese colony in South America. In the first two centuries of colonization, Indigenous and European groups lived in constant war, establishing opportunistic alliances in order to gain advantages against each other.

By the mid-16th century, cane sugar had become Brazil's most important export, while slaves purchased in Sub-Saharan Africa in the slave market of Western Africa (not only those from Portuguese allies of their colonies in Angola and Mozambique), had become its largest import, to cope with sugarcane plantations, due to increasing international demand for Brazilian sugar. Brazil received more than 2.8 million slaves from Africa between the years 1500 and 1800.

By the end of the 17th century, sugar exports began to decline and the discovery of gold by bandeirantes in the 1690s would become the new backbone of the colony's economy, fostering a gold rush which attracted thousands of new settlers to Brazil from Portugal and all Portuguese colonies around the world. This increased level of immigration in turn caused some conflicts between newcomers and old settlers.

Portuguese expeditions known as bandeiras gradually expanded Brazil's original colonial frontiers in South America to its approximately current borders. In this era, other European powers tried to colonize parts of Brazil, in incursions that the Portuguese had to fight, notably the French in Rio during the 1560s, in Maranhão during the 1610s, and the Dutch in Bahia and Pernambuco, during the Dutch–Portuguese War, after the end of Iberian Union.

The Portuguese colonial administration in Brazil had two objectives that would ensure colonial order and the monopoly of Portugal's wealthiest and largest colony: to keep under control and eradicate all forms of slave rebellion and resistance, such as the Quilombo of Palmares, and to repress all movements for autonomy or independence, such as the Inconfidência Mineira (1789).

In late 1807, Spanish and Napoleonic forces threatened the security of continental Portugal, causing Prince Regent John, in the name of Queen Maria I, to move the royal court from Lisbon to Rio de Janeiro. There they established some of Brazil's first financial institutions, such as its local stock exchanges and its National Bank, additionally ending the Portuguese monopoly on Brazilian trade and opening Brazil's ports to other nations. In 1809, in retaliation for being forced into exile, the Prince Regent ordered the conquest of French Guiana.

With the end of the Peninsular War in 1814, the courts of Europe demanded that Queen Maria I and Prince Regent John return to Portugal, deeming it unfit for the head of an ancient European monarchy to reside in a colony. In 1815, to justify continuing to live in Brazil, where the royal court had thrived for six years, the Crown established the United Kingdom of Portugal, Brazil and the Algarves, thus creating a pluricontinental transatlantic monarchic state. However, the leadership in Portugal, resentful of the new status of its larger colony, continued to demand the return of the court to Lisbon (see Liberal Revolution of 1820). In 1821, acceding to the demands of revolutionaries who had taken the city of Porto, John VI departed for Lisbon. There he swore an oath to the new constitution, leaving his son, Prince Pedro de Alcântara, as Regent of the Kingdom of Brazil.

Tensions between Portuguese and Brazilians increased and the Portuguese Cortes, guided by the new political regime imposed by the Liberal Revolution, tried to re-establish Brazil as a colony. The Brazilians refused to yield, and Prince Pedro decided to side with them, declaring the country's independence from Portugal on 7 September 1822. A month later, Prince Pedro was proclaimed the first Emperor of Brazil, with the royal title of Dom Pedro I, resulting in the founding of the Empire of Brazil.

The Brazilian War of Independence, which had already begun along this process, spread through the northern, northeastern regions and in the Cisplatina province. The last Portuguese soldiers surrendered on 8 March 1824; Portugal officially recognized Brazilian independence on 29 August 1825.

On 7 April 1831, worn down by years of administrative turmoil and political dissent with both liberals and conservatives, including an attempt of republican secession and unreconciled to the way that absolutists in Portugal had given in the succession of King John VI, Pedro I departed for Portugal to reclaim his daughter's crown after abdicating the Brazilian throne in favor of his five-year-old son and heir (Dom Pedro II).

As the new Emperor could not exert his constitutional powers until he came of age, a regency was set up by the General Assembly. In the absence of a charismatic figure who could represent a moderate face of power, a series of localized rebellions took place, such as the Cabanagem in Grão-Pará, the Malê Revolt in Salvador, the Balaiada (Maranhão), the Sabinada (Bahia), and the Ragamuffin War, which began in Rio Grande do Sul and was supported by Giuseppe Garibaldi. These emerged from the provinces' dissatisfaction with the central power, coupled with old and latent social tensions peculiar to a vast, slaveholding and newly independent nation state. This period of internal political and social upheaval, which included the Praieira revolt in Pernambuco, was overcome only at the end of the 1840s, years after the end of the regency, which occurred with the premature coronation of Pedro II in 1841.

During the last phase of the monarchy, internal political debate centered on the issue of slavery. The Atlantic slave trade was outlawed in 1850, as a result of the British Aberdeen Act and the Eusébio de Queirós Law, but only in May 1888, after a long process of internal mobilization and debate for an ethical and legal dismantling of slavery in the country, was the institution formally abolished with the approval of the Golden Law.

The foreign-affairs policies of the monarchy dealt with issues pertaining Brazil's neighboring countries in the Southern Cone. Long after the Cisplatine War that resulted in the independence of Uruguay, Brazil won three international wars during the 58-year reign of Pedro II: the Platine War, the Uruguayan War and the devastating Paraguayan War, the largest war effort in Brazilian history.

Although there was no desire among the majority of Brazilians to change the country's form of government, on 15 November 1889, in disagreement with the majority of the Imperial Army officers, as well as with rural and financial elites, the monarchy was overthrown by a military coup. A few days later, the national flag was replaced with a new design that included the national motto "Ordem e Progresso", influenced by positivism. 15 November is now Republic Day, a national holiday.

The early republican government was a military dictatorship, with the army dominating affairs both in Rio de Janeiro and in the states. Freedom of the press disappeared and elections were controlled by those in power. Not until 1894, following an economic crisis and a military one, did civilians take power, remaining there until October 1930.

In this first republican period, Brazil maintained a relative balance characterized by a success in resolving border disputes with neighboring countries, only broken by the Acre War (1899–1902) and its involvement in World War I (1914–1918), followed by a failed attempt to exert a prominent role in the League of Nations; Internally, from the crisis of Encilhamento and the Navy Revolts, a prolonged cycle of financial, political and social instability began until the 1920s, keeping the country besieged by various rebellions, both civilian and military.

Little by little, a cycle of general instability sparked by these crises undermined the regime to such an extent that in the wake of the murder of his running mate, the defeated opposition presidential candidate Getúlio Vargas, supported by most of the military, successfully led the Revolution of 1930. Vargas and the military were supposed to assume power temporarily, but instead closed down Congress, extinguished the Constitution, ruled with emergency powers and replaced the states' governors with his own supporters.

In the 1930s, three attempts to remove Vargas and his supporters from power failed. The first was the Constitutionalist Revolution in 1932, led by São Paulo's oligarchy. The second was a communist uprising in November 1935, and the third a putsch attempt by local fascists in May 1938. The 1935 uprising created a security crisis in which Congress transferred more power to the executive branch. The 1937 coup d'état resulted in the cancellation of the 1938 election and formalized Vargas as dictator, beginning the Estado Novo era. During this period, government brutality and censorship of the press increased.

During World War II, Brazil remained neutral until August 1942, when the country suffered retaliation by Nazi Germany and Fascist Italy in a strategic dispute over the South Atlantic, and, therefore, entered the war on the allied side. In addition to its participation in the battle of the Atlantic, Brazil also sent an expeditionary force to fight in the Italian campaign.

With the Allied victory in 1945 and the end of the fascist regimes in Europe, Vargas' position became untenable, and he was swiftly overthrown in another military coup, with democracy reinstated by the same army that had ended it 15 years earlier. Vargas committed suicide in August 1954 amid a political crisis, after having returned to power by election in 1950.

Several brief interim governments followed Vargas' suicide. Juscelino Kubitschek became president in 1956 and assumed a conciliatory stance towards the political opposition that allowed him to govern without major crises. The economy and industrial sector grew remarkably, but his greatest achievement was the construction of the new capital city of Brasília, inaugurated in 1960. Kubitschek's successor, Jânio Quadros, resigned in 1961 less than a year after taking office. His vice-president, João Goulart, assumed the presidency, but aroused strong political opposition and was deposed in April 1964 by a coup that resulted in a military dictatorship.

The new regime was intended to be transitory, but gradually closed in on itself and became a full dictatorship with the promulgation of the Fifth Institutional Act in 1968. Oppression was not limited to those who resorted to guerrilla tactics to fight the regime, but also reached institutional opponents, artists, journalists and other members of civil society, inside and outside the country through "Operation Condor". Like other authoritarian regimes, due to an economic boom, known as the "economic miracle", the Brazilian military dictatorship reached a peak in popularity in the early 1970s.

Slowly, however, the wear and tear of years of dictatorial power had not slowed the repression, even after the defeat of the leftist guerrillas. The inability to deal with the economic crises of the period and popular pressure made a redemocratization policy inevitable, which from the regime side was led by Generals Ernesto Geisel and Golbery do Couto e Silva. With the enactment of the Amnesty Law in 1979, Brazil began a slow return to democracy, which was completed during the 1980s.

Civilians returned to power in 1985 when José Sarney assumed the presidency. He became unpopular during his tenure through failure to control the economic crisis and hyperinflation he inherited from the military regime. Sarney's unsuccessful government led to the election in 1989 of the almost-unknown Fernando Collor, who was subsequently impeached by the National Congress in 1992. Collor was succeeded by his vice-president, Itamar Franco, who appointed Fernando Henrique Cardoso as Minister of Finance. In 1994, Cardoso devised a highly successful Plano Real that, after decades of failed economic plans made by previous governments attempting to curb hyperinflation, finally stabilized the Brazilian economy. Cardoso won the 1994 election, and again in 1998.

The peaceful transition of power from Cardoso to his main opposition leader, Luiz Inácio Lula da Silva (elected in 2002 and re-elected in 2006), was seen as proof that Brazil had achieved a long-sought political stability. However, sparked by discontent accumulated over decades from corruption, police brutality, inefficiencies of the political establishment and public service, numerous peaceful protests erupted in Brazil in the middle of the first term of Dilma Rousseff, who had succeeded Lula after winning election in 2010 and again in 2014 by narrow margins.

Rousseff was impeached by the Brazilian Congress in 2016, halfway into her second term, and replaced by her vice-president Michel Temer, who assumed full presidential powers after Rousseff's impeachment was accepted on 31 August. Large street protests for and against her took place during the impeachment process. The charges against her were fueled by political and economic crises along with evidence of involvement with politicians from all the primary political parties. In 2017, the Supreme Court requested the investigation of 71 Brazilian lawmakers and nine ministers of President Michel Temer's cabinet who were allegedly linked to the Petrobras corruption scandal. President Temer himself was also accused of corruption.

In the fiercely contested 2018 elections, the controversial conservative candidate Jair Bolsonaro of the Social Liberal Party (PSL) was elected president, winning in the second round against Fernando Haddad, of the Workers Party (PT), with the support of 55.13% of the valid votes. In the early 2020s, Brazil became one of the hardest hit countries during the COVID-19 pandemic, receiving the second-highest death toll worldwide after the United States. In May 2021, Luiz Inácio Lula da Silva stated that he would run for a third term in the 2022 Brazilian general election against Bolsonaro. In October 2022, Lula was in first place in the first round, with 48.43% of the support from the electorate, and received 50.90% of the votes in the second round. On 8 January 2023, a week after Lula's inauguration, a mob of Bolsonaro's supporters attacked Brazil's federal government buildings in the capital, Brasília, after several weeks of unrest.

Brazil occupies nearly half of the land area of South America (47.7%), including a large area along its eastern coast and much of the continent's interior. It borders Uruguay to the south; Argentina and Paraguay to the southwest; Bolivia and Peru to the west; Colombia to the northwest; and Venezuela, Guyana, Suriname, and France (French overseas region of French Guiana) to the north. It shares a border with every South American country except Ecuador and Chile.

The Brazilian territory also encompasses a number of oceanic archipelagos, such as Fernando de Noronha, Rocas Atoll, Saint Peter and Saint Paul Archipelago, and the islands of Trindade and Martim Vaz. Its size, relief, climate, and natural resources make Brazil geographically diverse. Including its Atlantic islands, Brazil lies between latitudes 6°N and 34°S, and longitudes 28° and 74°W.

Brazil is the fifth largest country in the world, and third largest in the Americas, with a total area of 8,515,767.049 km2 (3,287,956 sq mi), including 55,455 km2 (21,411 sq mi) of water. Brazil is the only country in the world that has the equator and the Tropic of Capricorn running through it. It spans four time zones; from UTC−5 comprising the state of Acre and the westernmost portion of Amazonas, to UTC−4 in the western states, to UTC−3 in the eastern states (the national time) and UTC−2 in the Atlantic islands.

The climate of Brazil comprises a wide range of weather conditions across a large area and varied topography, but most of the country is tropical. According to the Köppen system, Brazil hosts six major climatic subtypes: desert, equatorial, tropical, semiarid, oceanic and subtropical. The different climatic conditions produce environments ranging from equatorial rainforests in the north and semiarid deserts in the northeast, to temperate coniferous forests in the south and tropical savannas in central Brazil.

In Brazil, forest cover is around 59% of the total land area, equivalent to 496,619,600 hectares (ha) of forest in 2020, down from 588,898,000 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 485,396,000 hectares (ha) and planted forest covered 11,223,600 hectares (ha). Of the naturally regenerating forest, 44% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 30% of the forest area was found within protected areas. For 2015, 56% of the forest area was reported to be under public ownership and 44% private ownership.

Many regions have starkly different microclimates. An equatorial climate characterizes much of northern Brazil. There is no real dry season, but there are some variations in the period of the year when most rain falls. Temperatures average 25 °C (77 °F), with more significant temperature variation between night and day than between seasons. Over central Brazil, rainfall is more seasonal, characteristic of a savanna climate. This region is as extensive as the Amazon basin but has a very different climate as it lies farther south at a higher altitude. In the interior northeast, seasonal rainfall is even more extreme. South of Bahia, near the coasts, and more southerly most of the state of São Paulo, the distribution of rainfall changes, with rain falling throughout the year. The south enjoys subtropical conditions, with cool winters and average annual temperatures not exceeding 18 °C (64.4 °F); winter frosts and snowfall are not rare in the highest areas.

The semiarid climatic region generally receives less than 800 millimeters (31.5 in) of rain, most of which generally falls in a period of three to five months of the year and occasionally less than this, creating long periods of drought. Brazil's 1877–78 Grande Seca (Great Drought), the worst in Brazil's history, caused approximately half a million deaths. A similarly devastating drought occurred in 1915. In 2024, for the first time, "a drought has covered all the way from the North to the country's Southeast". It is the strongest drought in Brazil since the beginning of measurement in the 1950s, covering almost 60% of the country's territory. The drought is linked to deforestation and climate change.

Climate change in Brazil is causing higher temperatures and longer-lasting heatwaves, changing precipitation patterns, more intense wildfires and heightened fire risk. Brazil's hydropower, agriculture and urban water supplies will be affected. Brazil's rainforests, and the Amazon, are particularly at risk to climate change. At worst, large areas of the Amazon River basin could turn into savannah, with severe consequences for global climate and local livelihoods. Extreme weather events like droughts and flash floods are causing annual losses of around R$13 billion (US$2.6 billion), equivalent to 0.1% of the country's 2022 GDP. Climate impacts could exacerbate poverty.

Brazil's greenhouse gas emissions per person are higher than the global average, and Brazil is among the top 10 highest emitting countries. Greenhouse gas emissions by Brazil are over 4% of the annual world total. In 2026 the Brazilian government has launched a National Climate Change Plan which should cut greenhouse gas emissions by 59% - 67% by 2035, and make the country carbon neutral by 2050. Brazil hosted the 2025 United Nations Climate Change Conference, in which it launched the Global carbon market coalition immediately joined by 11 countries including Brazil, China, the European Union, United Kingdom. According to some calculations, a global carbon market can speed up emission reduction seven-fold.

Brazilian topography is also diverse and includes hills, mountains, plains, highlands, and scrublands. Much of the terrain lies between 200 meters (660 ft) and 800 meters (2,600 ft) in elevation. The main upland area occupies most of the southern half of the country. The northwestern parts of the plateau consist of broad, rolling terrain broken by low, rounded hills.

The southeastern section is more rugged, with a complex mass of ridges and mountain ranges reaching elevations of up to 1,200 meters (3,900 ft). These ranges include the Mantiqueira and Espinhaço mountains and the Serra do Mar. In the north, the Guiana Highlands form a major drainage divide, separating rivers that flow south into the Amazon Basin from rivers that empty into the Orinoco River system, in Venezuela, to the north. The highest point in Brazil is the Pico da Neblina at 2,994 meters (9,823 ft), and the lowest is the Atlantic Ocean.

Brazil has a dense and complex system of rivers, one of the world's most extensive, with eight major drainage basins, all of which drain into the Atlantic. Major rivers include the Amazon (the world's largest in terms of water volume), the Paraná and its major tributary the Iguaçu (which includes the Iguazu Falls), the Negro, São Francisco, Xingu, Madeira and Tapajós rivers.

The wildlife of Brazil comprises all naturally occurring animals, plants, and fungi in the South American country. Home to 60% of the Amazon rainforest, which accounts for approximately one-tenth of all species in the world, Brazil is considered to have the greatest biodiversity of any country on the planet, containing over 70% of all animal and plant species catalogued. Brazil has the most known species of plants (55,000), freshwater fish (3,000) and mammals (over 689). It also ranks third on the list of countries with the most bird species (1,832) and second with the most reptile species (744). The number of fungal species is unknown but is large. Brazil is second only to Indonesia as the country with the most endemic species.

Brazil's large territory comprises different ecosystems, such as the Amazon rainforest, recognized as having the greatest biological diversity in the world, with the Atlantic Forest and the Cerrado sustaining the greatest biodiversity. In the south, the Araucaria moist forests grow under temperate conditions. The rich wildlife of Brazil reflects the variety of natural habitats. Scientists estimate that the total number of plant and animal species in Brazil could approach four million, mostly invertebrates. Larger mammals include carnivores pumas, jaguars, ocelots, rare bush dogs, and South American foxes, and herbivores peccaries, tapirs, anteaters, sloths, opossums and armadillos. Deer are plentiful in the south, and many species of New World monkeys are found in the northern rainforests.

More than one-fifth of the Amazon rainforest in Brazil has been completely destroyed, and more than 70 mammals are endangered. The threat of extinction comes from several sources, including deforestation and poaching. Extinction is even more problematic in the Atlantic Forest, where nearly 93% of the forest has been cleared. Of the 202 endangered animals in Brazil, 171 are in the Atlantic Forest. The Amazon rainforest has been under direct threat of deforestation since the 1970s because of rapid economic and demographic expansion. Extensive legal and illegal logging destroy forests the size of a small country per year, and with it a diverse series of species through habitat destruction and habitat fragmentation. Since 1970, over 600,000 square kilometers (230,000 sq mi) of the Amazon rainforest have been cleared by logging.

In 2017, preserved native vegetation occupied 61% of the Brazilian territory. Agriculture occupied only 8% of the national territory and pastures 19.7%. For comparison, in 2019, although 43% of the entire European continent has forests, only 3% of the total forest area in Europe is of native forest. Brazil has a strong interest in conservation, as its agriculture sector directly depends on its forests.

The form of government is a democratic federative republic, with a presidential system, as decided in a 1993 referendum. The president is both head of state and head of government of the Union and is elected for a four-year term, with the possibility of re-election for a second successive term. The current president is Luiz Inácio Lula da Silva. The president appoints the Ministers of State, who form the cabinet and assist in government.

Legislative houses in each political entity are the main source of law in Brazil. The National Congress is the federation's bicameral legislature, consisting of the Chamber of Deputies and the Federal Senate. The Senate represents the 26 states and the Federal District. Each state and the Federal District has a representation of three senators, who are elected by popular ballot for a term of eight years. The Chamber of Deputies represents the people of each state, and its members are elected for a four-year term by a system of proportional representation. Judiciary authorities exercise jurisdictional duties almost exclusively.

According to International IDEA's Global State of Democracy (GSoD) Indices and Democracy Tracker, Brazil performs in the mid to high range on overall democratic measures, with particular strengths in inclusive suffrage, freedom of religion, and civic engagement. In 2021, the Economist Intelligence Unit's Democracy Index categorized Brazil as a "flawed democracy", ranking 46th in the report, and Freedom House classified it as a free country at Freedom in the World report. According to the Regimes of the World classification Brazil was an electoral democracy in year 2024.

The political-administrative organization of the Federative Republic of Brazil comprises the Union, the states, the Federal District, and the municipalities. The Union, the states, the Federal District, and the municipalities, are the "spheres of government". The federation is set on five fundamental principles: sovereignty, citizenship, dignity of human beings, the social values of labor and freedom of enterprise, and political pluralism.

The classic tripartite branches of government (executive, legislative and judicial under a checks and balances system) are formally established by the constitution. The executive and legislative are organized independently in all three spheres of government, while the judiciary is organized only at the federal and state and Federal District spheres. All members of the executive and legislative branches are directly elected.

For most of its democratic history, Brazil has had a multi-party system, with proportional representation. Voting is compulsory for the literate between 18 and 70 years old and optional for illiterates and those between 16 and 18 or beyond 70. The country has around 30 registered political parties. Twenty political parties are represented in Congress. It is common for politicians to switch parties, and thus the proportion of congressional seats held by particular parties changes regularly.

Brazilian law is based on the civil law legal system and civil law concepts prevail over common law practice. Most of Brazilian law is codified, although non-codified statutes also represent a substantial part, playing a complementary role. Court decisions set out interpretive guidelines; however, they are seldom binding on other specific cases. Doctrinal works and the works of academic jurists have strong influence in law creation and in law cases. Judges and other judicial officials are appointed after passing entry exams.

The legal system is based on the Federal Constitution, promulgated on 5 October 1988, and the fundamental law of Brazil. All other legislation and court decisions must conform to its rules. As of July 2022, there have been 124 amendments. The highest court is the Supreme Federal Court. States have their own constitutions, which must not contradict the Federal Constitution. Municipalities and the Federal District have "organic laws" (leis orgânicas), which act in a similar way to constitutions. Legislative entities are the main source of statutes, although in certain matters judiciary and executive bodies may enact legal norms. Jurisdiction is administered by the judiciary entities, although in rare situations the Federal Constitution allows the Federal Senate to pass on legal judgments. There are also specialized military, labor and electoral courts.

Brazil is a federation composed of 26 states, one federal district, and the 5,571 municipalities. States have autonomous administrations, collect their own taxes and receive a share of taxes collected by the Federal government. They have a governor and a unicameral legislative body elected directly by their voters. They also have independent Courts of Law for common justice. States have the ability to create their own laws and establish their own constitutions but criminal and civil laws can be voted by only the federal bicameral Congress and are uniform throughout the country.

Municipalities, as the states, have autonomous administrations, collect their own taxes and receive a share of taxes collected by the federal and state government. Each has an elected mayor and legislative body, but no separate Court of Law. Indeed, a Court of Law organized by the state can encompass many municipalities in a single justice administrative division called comarca.

Brazil's constitution also provides for the creation of federal territories, which are administrative divisions directly controlled by the federal government. However, there are currently no federal territories in the country, as the 1988 constitution abolished the last three: Amapá and Roraima (which gained statehood) and Fernando de Noronha, which became a state district of Pernambuco.

Brazil's international relations are based on Article 4 of the Federal Constitution, which establishes non-intervention, self-determination, international cooperation and the peaceful settlement of conflicts as the guiding principles of Brazil's relationship with other countries and multilateral organizations. According to the constitution, the president has ultimate authority over foreign policy, while Congress is tasked with reviewing and considering all diplomatic nominations and international treaties, as well as legislation relating to Brazilian foreign policy.

Brazil's foreign policy is a by-product of the country's position as a regional power in Latin America, a leader among developing countries, and an emerging world power. Brazilian foreign policy has generally been based on the principles of multilateralism, peaceful dispute settlement, and non-intervention in the affairs of other countries. Brazil is a founding member state of the Community of Portuguese Language Countries (CPLP), also known as the Lusophone Commonwealth, an international organization and political association of Lusophone nations.

An increasingly well-developed tool of Brazil's foreign policy is providing aid as a donor to other developing countries. Brazil does not just use its growing economic strength to provide financial aid, but it also provides high levels of expertise and most importantly of all, a quiet non-confrontational diplomacy to improve governance levels. Total aid is estimated to be around $1 billion per year. In addition, Brazil already managed a peacekeeping mission in Haiti ($350 million) and makes in-kind contributions to the World Food Programme ($300 million). The scale of this aid places it on par with China and India. The Brazilian South-South aid has been described as a "global model in waiting".
