Location of Acre in Brazil

The 1988 Brazilian Constitution treats the municipalities as parts of the Federative Republic of Brazil and not dependent subdivisions of the states. Each municipality has an autonomous local government, comprising a mayor (prefeito) and a legislative body called municipal chamber (câmara municipal). Both the local government and the legislative body are directly elected by the population every four years with the more recent municipal elections held on 15 November 2022. Each municipality has the constitutional power to approve its own laws, as well as collecting taxes and receiving funds from the state and federal governments. Municipal governments do not have judicial power per se, and courts are only organised at the state or federal level. A subdivision of the state judiciary, or comarca, can either correspond to an individual municipality or encompass several municipalities. The seat of the municipal administration is a nominated city (cidade), with no specification in the law about the minimum population, area or facilities. The city always has the same name as the municipality, as they are not treated as distinct entities. Municipalities can be subdivided, only for administrative purposes, into districts (normally, new municipalities are formed from these districts). Other populated sites are villages, but with no legal effect or regulation. Almost all municipalities are subdivided into neighbourhoods (bairros), although most municipalities do not officially define their neighbourhood limits (usually small cities in the countryside). Municipalities can be split or merged to form new municipalities within the borders of the state, if the population of the involved municipalities expresses a desire to do so in a plebiscite. However, these must abide by the Brazilian Constitution, and forming exclaves or seceding from the state or union is expressly forbidden.^[4]

The largest municipality by population is the state capital Rio Branco, with 378,476 residents, while the smallest is Santa Rosa do Purus, with 6,723 residents.^[5] The largest municipality by land area is Feijó, which spans 27,974.60 km² (10,801.05 sq mi), and the smallest is Epitaciolândia, with 1,654.80 km² (638.92 sq mi).^[6]
