Brazil is divided into federative units which have a certain degree of autonomy (self-government, self-regulation, and self-collection) and are endowed with their own government and constitution. There are26 states (estados) andone federal district (distrito federal). The states are generally based on historical, conventional borders which have developed over time. The states are divided intomunicipalities, while theFederal District assumes the competences of both a state and a municipality.
The state executive branch is headed by a state governor and includes a vice governor, both elected by the citizens of the state. The governor appoints several secretaries of state (each one in charge of a given portfolio) and the state attorney-general.[1]
The state legislative branch is the legislative assembly, aunicameral body composed of deputies elected by the citizens of the state.[1]
The judiciary in each of the states is composed of judges of law, who constitute thecourts of first instance, and aCourt of Justice, which is the court of second instance of the state and is composed of judges calleddesembargadores. Judges qualify through exams or are appointed.[1]
The states are divided intomunicipalities, which have different competences and are considered autonomous from the states. Municipalities have a mayor, vice mayor and a chamber of aldermen, all elected by the citizens of the municipality, but do not have a separate judiciary.[1]
TheFederal District has the same executive, legislative and judiciary organization as a state, but it cannot be divided into municipalities, which is why its territory is composed of severaladministrative regions. These regions are directly managed by the government of the Federal District, which exercises constitutional and legal powers that are equivalent to those of thestates, as well as those of the municipalities, thus simultaneously assuming all the obligations arising from them.[1]
Fernando de Noronha is not a municipality, but a state district of Pernambuco (the only state district in the country). It is governed by an administrator-general, appointed by the governor of Pernambuco, and a council whose members are elected by the citizens of the district.[2]
All states and the Federal District are represented in thenational congress, each with threesenators and between eight and 70deputies, depending on their population. The citizens of all states and the Federal District vote for these national representatives and forpresident andvice president.

The present states of Brazil trace their history directly to thecaptaincies established byPortugal following theTreaty of Tordesillas which divided the World between Portugal and Spain.
The first administrative divisions of Brazil were the hereditary captaincies (capitanias hereditárias), stretches of land granted by the Portuguese Crown to noblemen or merchants with a charter to colonize the land. The first such captaincy was theisland of São João, granted in 1504 toFernão de Loronha. The continental land was divided into captaincies in 1534, generally following lines of latitude, although some followed meridians or diagonal lines.[3] Each of the holders of these captaincies was referred to as acaptain donatary (capitão donatário). The captaincies were to be inherited by the holders' descendants, but the Crown retained the power to reacquire them.
In 1549, the Portuguese Crown appointedTomé de Sousa as the firstgovernor-general of the vast Portuguese dominion in South America, known as theState of Brazil (Estado do Brasil). In 1621, the northern part of the dominion was detached, becoming a separate entity known as theState of Maranhão. However, captaincies continued existing under both states as regional administrations.[4]
During theIberian Union (1580–1640), which allowed Portuguese settlers to enter Spanish domains, the territory of Portuguese colonial domains in South America was more than doubled, with both states of Brazil and Maranhão greatly expanding westward. After the union ended, Portugal asserted its territorial claims, which Spain eventually accepted with theTreaty of Madrid in 1750. Several captaincies were created or merged during this period, in both the original and western domains, and some were returned to the Crown, becoming royal captaincies.[4]
The government of theMarquis of Pombal (1750–1777) significantly centralized the administration of the Portuguese colonies. By 1759, all captaincies had been returned to the Crown, with captains becoming appointed rather than recognized by inheritance. Some captaincies were designated ascaptaincies-general, to which other captaincies were subordinated.[4] In addition, theState of Grão-Pará and Rio Negro and theState of Maranhão and Piauí, which had been split from the State of Maranhão, were reincorporated into the State of Brazil in 1775, under a single governor-general. This centralization later helped to keep Brazil as a unified nation-state, avoiding fragmentation similar to that of the Spanish domains.
When Brazil became a republic in 1889, all provinces became states, and the Neutral Municipality became the Federal District. In 1903, Brazil acquired the territory ofAcre fromBolivia with theTreaty of Petrópolis.
In 1942–1943, with the entrance of Brazil intoWorld War II, theVargas regime detached six strategic territories from the borders of the country to administer them directly: the archipelago ofFernando de Noronha (from Pernambuco),Amapá (from Pará),Rio Branco (from Amazonas),Guaporé (fromMato Grosso and Amazonas),Ponta Porã (from Mato Grosso) andIguaçu (from Paraná andSanta Catarina).[5][6][7] Shortly after the war, the Brazilian constitution of 1946 returned Ponta Porã and Iguaçu to their original states.[8] Guaporé was renamed Rondônia in 1956,[9] and Rio Branco was renamed Roraima in 1962,[10] while remaining territories along with Amapá and Fernando de Noronha. Acre became a state in 1962.[11]
In 1960, the rectangular-shapedDistrito Federal was carved out of Goiás to contain the new capital,Brasília.[12][13] The previous federal district became the state ofGuanabara,[8] but in 1975 it was reincorporated into its original state ofRio de Janeiro, becoming its capital as the city of Rio de Janeiro.[14]
In 1977, the southern part of Mato Grosso became the state ofMato Grosso do Sul.[15] In 1981, Rondônia became a state.[16] TheBrazilian constitution of 1988 created the state ofTocantins from the northern portion of Goiás, established Amapá and Roraima as states, and returned the archipelago of Fernando de Noronha to Pernambuco.[1] The constitution thus ended all remaining territories, although it maintained the possibility of creating others in the future.
On 11 December 2011, a consultativereferendum was held in the state ofPará about creating two new states from parts of it (Tapajós andCarajás, with the rest of the state remaining as Pará). Both proposals were rejected by about 66% of statewide voters, but reflecting a strong geographic split with over 90% approval by voters in the proposed breakaway regions and over 90% disapproval by those in the rest of the state.[17][18]
