The
President of Brazil, officially the
President of the Federative Republic of Brazil , or simply the
President of the Republic, is both
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
Emperor Pedro II. Since then, Brazil has had six
constitutions, three dictatorships, and three democratic periods. During these democratic periods, voting has always been
compulsory. The Brazilian
Federal Constitution, 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.
