Brazil is the only Portuguese-speaking nation in the Americas.
Brazil was claimed for Portugal in 1500 by Pedro Alvares Cabral. It was ruled from Lisbon as a colony until 1808, when the royal family, having fled from Napoleon's army, established the seat of Portuguese Government in Rio de Janeiro. Brazil became a kingdom under Dom Joao VI, who returned to Portugal in 1821. His son, Dom Pedro II, ruled from 1831 to 1889, when a federal republic was established in a coup by Deodoro da Fonseca, marshal of the army. Slavery had been abolished a year earlier by the Regent Princess Isabel while Dom Pedro II was in Europe.
