Brazilo
Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of
explorer Pedro lvares Cabral, who claimed the area for the Portuguese Empire. Brazil
remained a Portuguese colony until 1808, when the capital of the empire was transferred
from Lisbon to Rio de Janeiro. In 1815, the colony was elevated to the rank of kingdom
upon the formation of the United Kingdom of Portugal, Brazil and the
Algarves. Independence was achieved in 1822 with the creation of the Empire of Brazil, a
unitary state governed under a constitutional monarchy and a parliamentary system. The
ratification of the first constitution in 1824 led to the formation of a bicameral legislature,
now called the National Congress. The country became a presidential republic in 1889
following a military coup d'tat. An authoritarian military junta came to power in 1964 and
ruled until 1985, after which civilian governance resumed. Brazil's current constitution,
formulated in 1988, defines it as a democratic federal republic.[17] The federation is
composed of the union of the Federal District, the 26 states, and the 5,570 municipalities.
