The Viceroyalty of Brazil (Portuguese: Vice-Reino do Brasil) comprises the period from 1500, with the arrival of the Portuguese, until 1815, when Brazil was elevated to kingdom alongside Portugal as the United Kingdom of Portugal, Brazil and the Algarves.

During the over 300 years of Brazilian colonial history, the economic exploration of the territory was based first on brazilwood extraction (16th century), sugar production (16th–18th centuries), and finally on gold and diamond mining (18th century). Slaves, especially those brought from Africa, provided most of the working force of Brazilian economy.

In contrast to the neighbouring fragmented Spanish possessions, the Portuguese colony, built up by the Portuguese in Latin America, kept its territorial unity and linguistic integrity after the independence, giving rise to the largest country in the region.

Portugal and Spain pioneered the European discovery of sea routes that were the first channels of interaction between all of the World's continents, thus beginning the process of globalization. In addition to the adventurous undertaking of discovery and colonization of far off lands, these years were filled with pronounced advancements in cartography, shipbuilding and navigational instruments, from which the Portuguese and Spanish explorers took advantage.

Brazil was a colony of Portugal from the landing of Pedro Álvares Cabral in 1500 until 1815, when it was elevated to the rank of kingdom and the United Kingdom of Portugal, Brazil and the Algarves was formed. The colonial bond was in fact broken in 1808, when the capital of the Portuguese colonial empire was transferred from Lisbon to Rio de Janeiro, after Napoleon invaded Portugal.Independence was achieved in 1822 with the formation of the Empire of Brazil, a unitary state governed under a constitutional monarchy and a parliamentary system. The country became a presidential republic in 1889, when a military coup d'état proclaimed the Republic, although the bicameral legislature, now called Congress, dates back to the ratification of the first constitution in 1824. Its current Constitution, formulated in 1988, defines Brazil as a Federal Republic. The Federation is formed by the union of the Federal District, the 26 States, and the 5,564 Municipalities.
