The Brazilian Government operates as a federal republic, meaning it has a system where power is divided between the national and state governments. It consists of three branches: the executive, led by the President, the legislative, which includes the National Congress, and the judiciary, responsible for interpreting laws. This structure ensures a system of checks and balances. Elections in Brazil are held every four years, allowing citizens to vote for their President, members of Congress, and state governors. The government is responsible for various functions, including public services, education, and infrastructure, aiming to promote the welfare of its citizens.
