Brazil - Officially the Federative Republic of Brazil (Portuguese: República Federativa do Brasil),
is the largest country in both South America and the Latin American region. It is the world's
fifth largest country, both by geographical area and by population. It is the largest Portuguese-
speaking country in the world, and the only one in the Americas.
Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro
Alvares 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.
