The president of Brazil (officially the President of the Federative Republic of Brazil or simply the President of the Republic) is both the head of state and head of government of the Federative Republic of Brazil. The president leads the executive branch of the federal government and is the commander-in-chief of the Brazilian Armed Forces. The presidential system was established in 1889, upon the proclamation of the republic in a military coup d'état against the Emperor Dom Pedro II. Since then, Brazil had six constitutions, two dictatorships and three democratic periods. During these democratic periods, voting has always been compulsory.

The Brazilian Constitution of 1988, along with several constitutional amendments, establishes the requirements, powers, and responsibilities of the president, as well as the term of office and method of election.

As a republic with a presidential Executive, Brazil grants significant powers to the President. He or she effectively controls the Executive branch, represents the country abroad, and appoints the Cabinet and, with the approval of the Senate, the judges for the Supreme Federal Tribunal. The president is also the Commander-in-Chief of the armed forces.

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.
