74-534: Amapá ( [amaˈpa] ) is one of the 26 states of Brazil . It is in the North Region of Brazil . It is the second-least populous state and the eighteenth-largest state by area . Located in the far northern part of the country, Amapá is bordered clockwise by French Guiana to the north for 730 km, the Atlantic Ocean to the east for 578 km, Pará to the south and west, and Suriname to

148-438: A continuous tree canopy which would prevent further grass growth. Prior to European settlement aboriginal land use practices, including fire, influenced vegetation and may have maintained and modified savanna flora. It has been suggested by many authors that aboriginal burning created a structurally more open savanna landscape. Aboriginal burning certainly created a habitat mosaic that probably increased biodiversity and changed

222-491: A dramatic reduction in basal area and canopy cover, often leaves a high percentage of woody plants alive either as seedlings too small to be affected or as plants capable of re-sprouting from lignotubers and broken stumps. A population of woody plants equal to half or more of the original number often remains following pulling of eucalypt communities, even if all the trees over 5 metres are uprooted completely. A number of exotic plants species have been introduced to savannas around

296-402: A means of clearing land. In the 1950s arboricides suitable for stem injection were developed. War-surplus heavy machinery was made available, and these were used for either pushing timber, or for pulling using a chain and ball strung between two machines. These two new methods of timber control, along with the introduction and widespread adoption of several new pasture grasses and legumes promoted

370-444: A reduction in the need to burn to produce a flush of green growth because legumes retain high nutrient levels throughout the year, and because fires can have a negative impact on legume populations which causes a reluctance to burn. The closed forest types such as broadleaf forests and rainforests are usually not grazed owing to the closed structure precluding grass growth, and hence offering little opportunity for grazing. In contrast

444-469: A resurgence in tree clearing. The 1980s also saw the release of soil-applied arboricides, notably tebuthiuron , that could be utilised without cutting and injecting each individual tree. In many ways "artificial" clearing, particularly pulling, mimics the effects of fire and, in savannas adapted to regeneration after fire as most Queensland savannas are, there is a similar response to that after fire. Tree clearing in many savanna communities, although causing

518-460: A short dry season and heavy rainfall for the majority of the year. In the Köppen climate classification , it is classified under the letters Am . Tropical rainforest is the natural vegetation, and also provides the other climate type located in the state. According to the 2022 census , there were 733,759 people residing in the state, with a population density of 5.1/km. The population of Amapá

592-459: A simplified yet widespread climatic concept. The divergence has sometimes caused areas such as extensive savannas north and south of the Congo and Amazon Rivers to be excluded from mapped savanna categories. In different parts of North America, the word "savanna" has been used interchangeably with " barrens ", " prairie ", " glade ", "grassland" and " oak opening ". Different authors have defined

666-569: Is a ferry to Monte Dourado in Pará . In Port Santana , there is a ferry to Belém , Pará. There is a small port in Macapá; however, it is not suitable for cargo traffic. The main harbour is the Port of Santana which is also used for international cargo. The flag was adopted by Decree No. 8 of 23 April 1984. The blue represents the sky over Amapá and justice, the green represents the native rainforest, and

740-729: Is connected to the road network of French Guiana via the Oyapock River Bridge . BR-210 connects Macapá with Serra do Navio . It is supposed to be extended all the way to the border with Colombia in Amazonas ; however, as of 2021, it ends in the Wayampi Indigenous Territory. An important state road is the AP-010 which connects Macapá with Santana and Mazagão Velho . There are no road connections to other Brazilian states. In Laranjal do Jari there

814-438: Is divided into executive , legislative and judiciary branches. 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. The state legislative branch is the legislative assembly, a unicameral body composed of deputies elected by

888-429: Is highly urbanized, with 93.7% of the population residing primarily in Macapá and Santana . Population growth : 5.7% (1991–2000); Houses : 144,000 (2006). During the 2022 census, 65.3% identified as Pardo (multiracial), 21.4% as White Brazilians , 11.8% as Black Brazilians and 1.4% as Indigenous . The remaining 0.1% are Asians and undeclared. The majority of the residents of Amapá live in poverty. According to

962-483: Is not prominent but that rivers in savanna landscapes erode more by lateral migration . Flooding and associated sheet wash have been proposed as dominant erosion processes in savanna plains. The savannas of tropical America comprise broadleaved trees such as Curatella , Byrsonima , and Bowdichia , with grasses such as Leersia and Paspalum . Bean relative Prosopis is common in the Argentinian savannas. In

1036-779: Is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests. The South American savanna types cerrado sensu stricto and cerrado dense typically have densities of trees similar to or higher than that found in South American tropical forests, with savanna ranging from 800 to 3300 trees per hectare (trees/ha) and adjacent forests with 800–2000 trees/ha. Similarly Guinean savanna has 129 trees/ha, compared to 103 for riparian forest , while Eastern Australian sclerophyll forests have average tree densities of approximately 100 per hectare , comparable to savannas in

1110-473: Is possible for there to be multiple stable biomes. The annual rainfall ranges from 500 mm (19.69 in) to 1,270 mm (50.00 in) per year, with the precipitation being more common in six or eight months of the year, followed by a period of drought. Savannas may at times be classified as forests. In climatic geomorphology it has been noted that many savannas occur in areas of pediplains and inselbergs . It has been posited that river incision

1184-591: Is the northern end of Brazil's coastline. During the colonial era from 1637 to 1654 the Amapá region was merged into the Captaincy of Pará, which was the Captaincy of Cabo de Norte . In the early colonial period the Amapá region was a rich source of lumber , resins , annatto , vegetable oils, and salted fish , all of which were exported to Europe. The French established sugarcane plantations in this period. With

1258-513: Is the official national language, and thus the primary language taught in schools. French is the second language taught in every school due to the proximity of French Guiana . A Creole language called Lanc-Patuá is spoken among some of the people. The service sector is the largest component of GDP at 87.6%, followed by the industrial sector at 7.8%. Agriculture represents 4.6% of GDP (2004). Amapá exports: wood 75.5%, ores 18.7%, heart of palm 5.5% (2002). The state, which has 0.4% of

1332-419: Is vague and therefore the two can be combined into a single biome as both woodlands and savannas feature open-canopied trees with crowns not usually interlinking (mostly forming 25-60% cover). Over many large tropical areas, the dominant biome (forest, savanna or grassland) can not be predicted only by the climate, as historical events plays also a key role, for example, fire activity. In some areas, indeed, it

1406-446: Is widely found in water sources and sewage systems in the population centers of Amapá. To protect the natural resources of the state, there are, as of 2016, 12 protected areas and five indigenous territories covering 10,476,117 hectares (25,887,050 acres), or 72% of the state. The Amapá Biodiversity Corridor has been established in 2003 to provide integrated management for the conservation area. The most important protected areas are

1480-563: The Fundação Getulio Vargas (FGV) 36.56% of the population live on only R$ 79 per month, which the foundation considers below a decent standard of living. According to data obtained by the IBGE in the 2010 Brazilian Census, 64% of Amapá residents are Roman Catholics, 28% are evangelicals (Protestants) and 6% do not profess any religion. The other faiths added together add up to 2% of the population. The Catholic Church comprises

1554-875: The Karipuna do Amapá , the Palikur , the Wayampi and the Galibi Marwono . The region around the Amazon River used to support a large population of Amerindians during the pre-Columbian era. The policy of the Portuguese monarchy was to engage in war in order to clear them from the land. The Cabanagem Revolt in the 1830s, resulted in the final dispersal of the Amerindians along the Amazon. Portuguese

1628-462: The Mediterranean region were likewise created and maintained by anthropogenic fire. Intentional controlled burns typically create fires confined to the herbaceous layer that do little long term damage to mature trees. This prevents more catastrophic wildfires that could do much more damage. However, these fires either kill or suppress tree seedlings, thus preventing the establishment of

1702-562: The State of Grão-Pará and Rio Negro and the State 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. The captaincies became provinces in 1821, during

1776-593: The Tumucumaque Mountains National Park located in the west of the state, and the Cabo Orange National Park located near the coast. The Tumucumaque Mountains National Park is the world's largest tropical forest national park . The Cabo Orange National Park contains flooded grasslands and mangrove forests which are important fish nurseries. Most of Amapá has a Tropical monsoon climate , a tropical climate with

1850-588: The Vargas regime detached six strategic territories from the borders of the country to administer them directly: the archipelago of Fernando de Noronha (from Pernambuco), Amapá (from Pará), Rio Branco (from Amazonas), Guaporé (from Mato Grosso and Amazonas), Ponta Porã (from Mato Grosso) and Iguaçu (from Paraná and Santa Catarina ). Shortly after the war, the Brazilian constitution of 1946 returned Ponta Porã and Iguaçu to their original states. Guaporé

1924-640: The captaincies established by Portugal following the Treaty 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 the island of São João , granted in 1504 to Fernão de Loronha . The continental land

1998-476: The greenhouse effect may result in an alteration of the structure and function of savannas. Some authors have suggested that savannas and grasslands may become even more susceptible to woody plant encroachment as a result of greenhouse induced climate change . However, a recent case described a savanna increasing its range at the expense of forest in response to climate variation, and potential exists for similar rapid, dramatic shifts in vegetation distribution as

2072-694: The prairies in North America and steppes in Eurasia , which feature cold winters, savannas are mostly located in areas having warm to hot climates, such as in Africa, Australia, Thailand, South America and India. The word derives from the Spanish sabana , which is itself a loanword from Taíno , which means "treeless grassland" in the West Indies . The letter b in Spanish, when positioned in

2146-566: The Amapá claim through international arbitration in Geneva on 1 December 1900, which was found in favour of Brazil. It was subsequently incorporated into the state of Pará , as Araguari after the Araguari River and in 1943 this became the federal territory of Amapá. The discovery of rich manganese deposits in Serra do Navio in 1945 revolutionized the local economy. Manganese remains

2220-554: The Australian savanna, mammals in the family Macropodidae predominate, such as kangaroos and wallabies, though cattle, horses, camels, donkeys and the Asian water buffalo , among others, have been introduced by humans. It is estimated that less than three percent of savanna ecosystems can be classified as highly intact. Reasons for savanna degradation are manifold, as outlined below. Savannas are subject to regular wildfires and

2294-581: The Brazilian population, is responsible for only 0.22% of the Brazilian GDP . The main airport of the state is Macapá International Airport . On 12 April 2019 a new terminal was opened replacing an older facility. Following its closure, the old terminal was demolished to make room for an enlarged apron which was completed by 2020. There are two federal highways in Amapá: BR-156 connects Laranjal do Jari , Macapá and Oiapoque . The highway

2368-522: The Crown, becoming royal captaincies. The government of the Marquis 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 as captaincies-general , to which other captaincies were subordinated. In addition,

2442-632: The Diocese of Macapá (1949) a suffragan diocese of the Archdiocese of Belém de Pará, under Bishop Pedro José Conti (2004) with 27 parishes. The Amerindians tribes in Amapá are located in the north near the Oiapoque River , and in the east in the Wayampi Indigenous Territory. All the indigenous territories in Amapá have been demarcated. The tribes living in Amapá are the Galibi do Oiapoque ,

2516-505: The East African savannas, Acacia , Combretum , baobabs , Borassus , and Euphorbia are a common vegetation genera. Drier savannas there feature spiny shrubs and grasses, such as Andropogon , Hyparrhenia , and Themeda . Wetter savannas include Brachystegia trees and Pennisetum purpureum , and elephant grass type. West African savanna trees include Anogeissus , Combretum , and Strychnos . Indian savannas are mostly cleared, but

2590-527: The Northern Territory, Australia savanna, and 480,000 ha of savanna were being cleared annually in Queensland in the 2000s, primarily to improve pasture production. Substantial savanna areas have been cleared of woody vegetation and much of the area that remains today is vegetation that has been disturbed by either clearing or thinning at some point in the past. Clearing is carried out by

2664-437: The citizens of the state. The judiciary in each of the states is composed of judges of law, who constitute the courts of first instance , and a Court of Justice , which is the court of second instance of the state and is composed of judges called desembargadores . Judges qualify through exams or are appointed. The states are divided into municipalities , which have different competences and are considered autonomous from

2738-443: The city of Rio de Janeiro. In 1977, the southern part of Mato Grosso became the state of Mato Grosso do Sul . In 1981, Rondônia became a state. The Brazilian constitution of 1988 created the state of Tocantins from the northern portion of Goiás, established Amapá and Roraima as states, and returned the archipelago of Fernando de Noronha to Pernambuco. The constitution thus ended all remaining territories, although it maintained

2812-415: The court of the cacique Carlos in present-day Panama . The accounts are inexact, but this is usually placed in present-day Madugandí or at points on the nearby Guna Yala coast opposite Ustupo or on Point Mosquitos . These areas are now either given over to modern cropland or jungle . Many grassy landscapes and mixed communities of trees, shrubs, and grasses were described as savanna before

2886-517: The decision to make it a state was made in 1988. The first state legislators took office on 1 January 1991. The dominant feature of the region, and 90 percent of its total area, is the Amazon rainforest . Unexplored forests occupy 70 percent of Amapá, and Tumucumaque Mountains National Park , established in 2002, is the largest tropical forest park in the world. The mouth of the River Oiapoque

The Treaty of Utrecht in 1713 established the boundaries between the colony of Brazil and French Guiana , but these were not respected by the French. A fort was constructed at São José de Macapá , in present-day Macapá, as a base of Portuguese power in

3034-566: The ecosystem appears to be the result of human use of fire. For example, Native Americans created the Pre-Columbian woodlands of North America by periodically burning where fire-resistant plants were the dominant species. Aboriginal burning appears to have been responsible for the widespread occurrence of savanna in tropical Australia and New Guinea , and savannas in India are a result of human fire use. The maquis shrub savannas of

Looking at Elephant impact on Savannas, the overall impact is reduced in the presence of rainfall and fences. Large areas of Australian and South American savannas have been cleared of trees, and this clearing continues today. For example, land clearing and fracking threaten

3182-619: The final years of the Kingdom of Brazil ( united with Portugal ), and maintained that designation after independence in 1822 under the Empire of Brazil . Most internal boundaries were kept unchanged from the end of the colonial period, generally following natural features such as rivers and mountain ridges. Some changes were made to suit domestic politics (transferring the Triângulo Mineiro from Goiás to Minas Gerais , transferring

3256-564: The first governor-general of the vast Portuguese dominion in South America, known as the State of Brazil ( Estado do Brasil ). In 1621, the northern part of the dominion was detached, becoming a separate entity known as the State of Maranhão . However, captaincies continued existing under both states as regional administrations. During the Iberian Union (1580–1640), which allowed Portuguese settlers to enter Spanish domains,

3330-490: The government of the Federal District, which exercises constitutional and legal powers that are equivalent to those of the states , as well as those of the municipalities, thus simultaneously assuming all the obligations arising from them. 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

3404-475: The governor of Pernambuco, and a council whose members are elected by the citizens of the district. All states and the Federal District are represented in the national congress , each with three senators and between eight and 70 deputies , depending on their population. The citizens of all states and the Federal District vote for these national representatives and for president and vice president . The present states of Brazil trace their history directly to

3478-483: The grazing industry in an attempt to increase the quality and quantity of feed available for stock and to improve the management of livestock. The removal of trees from savanna land removes the competition for water from the grasses present, and can lead to a two to fourfold increase in pasture production, as well as improving the quality of the feed available. Since stock carrying capacity is strongly correlated with herbage yield, there can be major financial benefits from

3552-402: The ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; savanna woodland where trees and shrubs form a light canopy, tree savanna with scattered trees and shrubs, shrub savanna with distributed shrubs, and grass savanna where trees and shrubs are mostly nonexistent. Savannas maintain an open canopy despite a high tree density. It

3626-428: The largest source of revenue in the state. Amapá's move to statehood was made on 5 October 1988, at the time of the promulgation of the new Brazilian Constitution , with the first state legislators taking office at the start of 1991. The State of Amapá possesses the lowest rate of loss of its original vegetation for any Brazilian state, estimated at only 2%. Most of the Amapá territory is covered with rainforest , while

3700-568: The lower limits of savanna tree coverage as 5–10% and upper limits range as 25–80% of an area. Two factors common to all savanna environments are rainfall variations from year to year, and dry season wildfires . In the Americas , e.g. in Belize , Central America , savanna vegetation is similar from Mexico to South America and to the Caribbean . The distinction between woodland and savanna

3774-465: The middle of a word, is pronounced almost like an English v; hence the change of grapheme when transcribed into English. The word originally entered English as the Zauana in a description of the ilands of the kinges of Spayne from 1555. This was equivalent in the orthography of the times to zavana (see history of V ). Peter Martyr reported it as the local name for the plain around Comagre,

3848-425: The middle of the 19th century, when the concept of a tropical savanna climate became established. The Köppen climate classification system was strongly influenced by effects of temperature and precipitation upon tree growth, and oversimplified assumptions resulted in a tropical savanna classification concept which considered it as a "climatic climax" formation. The common usage to describe vegetation now conflicts with

3922-422: The northwest for 63 km. The capital and largest city is Macapá . The state has 0.4% of the Brazilian population and is responsible for only 0.22% of the Brazilian GDP . In the colonial period the region was called Portuguese Guiana and was part of Portugal 's State of Brazil . Later, the region was distinguished from the other Guianas . Amapá was once part of Pará, but became a separate territory in 1943, and

3996-469: The open structure of savannas allows the growth of a herbaceous layer and is commonly used for grazing domestic livestock. As a result, much of the world's savannas have undergone change as a result of grazing by sheep, goats and cattle, ranging from changes in pasture composition to woody plant encroachment . The removal of grass by grazing affects the woody plant component of woodland systems in two major ways. Grasses compete with woody plants for water in

4070-460: The possibility of creating others in the future. On 11 December 2011, a consultative referendum was held in the state of Pará about creating two new states from parts of it ( Tapajós and Carajás , 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

4144-438: The potential to significantly alter the structure and composition of savannas worldwide, and have already done so in many areas through a number of processes including altering the fire regime, increasing grazing pressure, competing with native vegetation and occupying previously vacant ecological niches. Other plant species include: white sage, spotted cactus, cotton seed, rosemary. Human induced climate change resulting from

4218-485: The region. In the 18th century, France retook control of the area. This international dispute continued until 1900. The discovery of gold and the increasing value of rubber on the international market during the 19th century increased the Portuguese population of Amapá, bringing the dispute with France to a head. Although French settlers had established the Republic of Independent Guyana (1886–1891), Brazil challenged

4292-459: The remaining areas are covered with savannah and plains . On the Amapá coast, almost intact beaches mix with swamps, creating the largest representation of this biome in Brazil. This mixture of salt and fresh water is perfect for the food chain reproduction of several animal species. Pollution, however, is now a chronic problem in the state of Amapá. Mercury, which is used in the extraction of gold,

4366-431: The removal of trees, such as assisting with grazing management: regions of dense tree and shrub cover harbors predators, leading to increased stock losses, for example, while woody plant cover hinders mustering in both sheep and cattle areas. A number of techniques have been employed to clear or kill woody plants in savannas. Early pastoralists used felling and girdling , the removal of a ring of bark and sapwood , as

4440-585: The reserved ones feature Acacia, Mimosa , and Zizyphus over a grass cover comprising Sehima and Dichanthium . The Australian savanna is abundant with sclerophyllous evergreen vegetation, which include the eucalyptus , as well as Acacia, Bauhinia , Pandanus with grasses such as Heteropogon and kangaroo grass (Themeda). Animals in the African savanna generally include the giraffe, elephant, buffalo, zebra, gnu, hippopotamus, rhinoceros, and antelope, where they rely on grass and/or tree foliage to survive. In

4588-453: The same region. Savannas are also characterised by seasonal water availability, with the majority of rainfall confined to one season. They are associated with several types of biomes , and are frequently in a transitional zone between forest and desert or grassland , though mostly a transition between desert to forest. Savanna covers approximately 20% of the Earth's land area. Unlike

4662-515: The soil caused by the hooves of animals and through the erosion effects caused by the removal of protective plant cover. Such effects are most likely to occur on land subjected to repeated and heavy grazing. The effects of overstocking are often worst on soils of low fertility and in low rainfall areas below 500 mm, as most soil nutrients in these areas tend to be concentrated in the surface so any movement of soils can lead to severe degradation. Alteration in soil structure and nutrient levels affects

4736-474: The south bank of the São Francisco River from Pernambuco to Minas Gerais and later to Bahia , separating the capital city of Rio de Janeiro as a Neutral Municipality outside any province, splitting Amazonas from Pará , and splitting Paraná from São Paulo ), as well as international border adjustments resulting from diplomatic settlement of territorial disputes. The Cisplatine Province

4810-606: The spread of weeds in savannas by the removal or reduction of the plants which would normally compete with potential weeds and hinder establishment. In addition to this, cattle and horses are implicated in the spread of the seeds of weed species such as prickly acacia ( Acacia nilotica ) and stylo ( Stylosanthes species). Alterations in savanna species composition brought about by grazing can alter ecosystem function, and are exacerbated by overgrazing and poor land management practices. Introduced grazing animals can also affect soil condition through physical compaction and break-up of

4884-426: 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. The Federal 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 several administrative regions . These regions are directly managed by

4958-519: The structure of woodlands and geographic range of numerous woodland species. It has been suggested by many authors that with the removal or alteration of traditional burning regimes many savannas are being replaced by forest and shrub thickets with little herbaceous layer. The consumption of herbage by introduced grazers in savanna woodlands has led to a reduction in the amount of fuel available for burning and resulted in fewer and cooler fires. The introduction of exotic pasture legumes has also led to

5032-417: 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 the Treaty 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

5106-463: The topsoil and removal by grazing reduces this competitive effect, potentially boosting tree growth. In addition to this effect, the removal of fuel reduces both the intensity and the frequency of fires which may control woody plant species. Grazing animals can have a more direct effect on woody plants by the browsing of palatable woody species. There is evidence that unpalatable woody plants have increased under grazing in savannas. Grazing also promotes

5180-665: The world. Amongst the woody plant species are serious environmental weeds such as Prickly Acacia ( Acacia nilotica ), Rubbervine ( Cryptostegia grandiflora ), Mesquite ( Prosopis spp.), Lantana ( Lantana camara and L. montevidensis ) and Prickly Pear ( Opuntia spp.). A range of herbaceous species have also been introduced to these woodlands, either deliberately or accidentally including Rhodes grass and other Chloris species, Buffel grass ( Cenchrus ciliaris ), Giant rat's tail grass ( Sporobolus pyramidalis ) parthenium ( Parthenium hysterophorus ) and stylos ( Stylosanthes spp.) and other legumes . These introductions have

The black stands for the deceased who worked for the state, and the white for the will of the state to live in peace and stability. The symbol on the hoist-side represents the Fortress of São José, out of which the state capital grew. Before 1984, the state had a red-white-red flag, based on the flag of Pará , and similar to the flag of Peru . Federative units of Brazil Recent elections The government of each state of Brazil

5328-496: Was annexed into Brazil in 1821, declared independence as Uruguay in 1825, and was recognized by the Treaty of Montevideo in 1828. 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 of Acre from Bolivia with the Treaty of Petrópolis . In 1942–1943, with the entrance of Brazil into World War II ,

5402-412: Was divided into captaincies in 1534, generally following lines of latitude, although some followed meridians or diagonal lines. Each of the holders of these captaincies was referred to as a captain 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 appointed Tomé de Sousa as

In 1960, the rectangular-shaped Distrito Federal was carved out of Goiás to contain the new capital, Brasília . The previous federal district became the state of Guanabara , but in 1975 it was reincorporated into its original state of Rio de Janeiro , becoming its capital as
