The Federal Senate (Portuguese : Senado Federal) is the upper house of the National Congress of Brazil. When created within the Brazilian Empire in 1824, it was based on the British House of Lords, but since the Proclamation of the Republic in 1889 the Federal Senate has resembled the United States Senate. In its current form the Senate has 81 seats, three each for the Federal District and the 26 states. Senators sit for eight years, and elections are staggered so that either a third or two-thirds are up for election every four years.

The current president of the Brazilian Senate is Rodrigo Pacheco, from the Democrats of Minas Gerais. He was elected in early 2021 for a two-year term.


The Senate has 81 members, serving an eight-year term of office. There are three Senators from each of the country's 27 federative units, the Federal District and the 26 states. Elections are staggered so that either a third or two-thirds of Senators are up for election every four years. The most recent election took place in 2018, where two-thirds of the Senate was elected.

Electoral system

Elections are held under the first-past-the-post and block voting systems. In years when a third of members are up for election, voters can cast only one vote and the candidate who receives a plurality of votes within their state is elected. In years when two-thirds of members are up for election, voters can cast two votes. People can not vote for the same candidate twice, but each party can field up to two candidates in each state. The two highest-placed candidates in each state are elected.


The Federal Senate of Brazil was established as the Senate of the Empire by the Constitution of 1824, first enacted after the Declaration of Independence. It was modelled on the British House of Lords. [2]

Following independence, in 1822, Emperor Pedro I ordered the convocation of a National Assembly to draft the country's first Constitution. Following several disagreements with the elected deputies (which included representatives from present-day Uruguay, then part of the Brazilian Empire under the name of Província Cisplatina ), the Emperor dissolved the Assembly. In 1824, Pedro I implemented the first Constitution which established a Legislative branch with the Chamber of Deputies as the lower house, and the Senate as an upper house.

The first configuration of the Senate was a consulting body to the Emperor. Membership was for life and it was a place of great prestige, to which only a small part of the population could aspire. The original Senate had 50 members, representing all of the Empire's provinces, each with a number of senators proportional to its population.

Members of the Senate were elected, but they had to be at least 40 years old and have an annual income of 800,000 contos-de-réis, which limited candidates to wealthy citizens. Voters also faced an income qualification. Voting in an election for the Senate was limited to male citizens with an annual income of at least 200,000 contos-de-réis. Those who qualified for this did not vote directly for Senators; instead, they voted for candidates to be Senate electors. To be a Senate elector required an annual income of 400,000 contos-de-réis. Once elected, these electors would then vote for senator. The election itself would not result in a winner automatically. The three candidates receiving the most votes would make up what was called a "triple list", from which the Emperor would select one individual that would be considered "elected". The Emperor usually chose the candidate with the most votes, but it was within his discretion to select whichever of the three individuals listed. The unelected Princes of the Brazilian Imperial House were senators by right and would assume their seats in the Senate upon reaching age 25.

Following the adoption of the 1824 Constitution the first session of the Senate took place in May 1826. The Emperor had repeatedly delayed calling the first election, which had led to accusations that he would attempt to establish an absolutist government.

The Proclamation of the Republic in 1889 ended the Brazilian Empire in favor of the First Republic. The 1891 Constitution was then adopted, transforming Brazil's provinces into states and the Senate into an elected body. This was retained under later constitutions, including the current 1988 Constitution. Now known as the Federal Senate, it resembles the United States Senate in that each state has the same number of Senators.

Twelfth Amendment to the United States Constitution 1804 amendment regulating presidential elections

The Twelfth Amendment to the United States Constitution provides the procedure for electing the president and vice president. It replaced the procedure provided in Article II, Section 1, Clause 3, by which the Electoral College originally functioned. The amendment was proposed by the Congress on December 9, 1803, and was ratified by the requisite three-fourths of state legislatures on June 15, 1804. The new rules took effect for the 1804 presidential election and have governed all subsequent presidential elections.

An electoral college is a set of electors who are selected to elect a candidate to particular offices. Often these represent different organizations, political parties or entities, with each organization, political party or entity represented by a particular number of electors or with votes weighted in a particular way.

United States Electoral College Electors of the U.S. president and vice president

The United States Electoral College is the group of presidential electors required by the Constitution to form every four years for the sole purpose of electing the president and vice president. Each state appoints electors according to its legislature, equal in number to its congressional delegation. Federal office holders cannot be electors. Of the current 538 electors, an absolute majority of 270 or more electoral votes is required to elect the president and vice president. If no candidate achieves an absolute majority there, a contingent election is held by the United States House of Representatives to elect the president, and by the United States Senate to elect the vice president.

Prudente José de Morais e Barros was the third President of Brazil. He is notable as the first civilian president of the country, the first to be elected by direct popular ballot under the permanent provisions of Brazil's 1891 Constitution, and the first to serve his term in its entirety. His presidency, which lasted from 15 November 1894 until 14 November 1898, was marked by the War of Canudos, a peasant revolt in the northeast of the country that was crushed by the Brazilian Army. He also had to face a break in diplomatic relations with Portugal that was successfully mediated by Queen Victoria of the United Kingdom.

Politics of the Empire of Brazil took place in a framework of a quasi-federal parliamentary representative democratic monarchy, whereby the Emperor of Brazil was the head of state and nominally head of government although the President of the Council of Ministers was effectively the de facto head, and of a multi-party system. Executive power was exercised by the government. Legislative power was vested in both the government and the two chambers of the General Assembly. The Judiciary was independent of the Executive and the Legislative. The Empire of Brazil was divided into 20 provinces and the Neutral City, capital of the country.

Elections in Brazil Elections

Brazil elects on the national level a head of state—the president—and a legislature. The president is elected to a four-year term by absolute majority vote through a two-round system.

The Federal Senate has 81 members, elected to an eight-year term, with elections every four years for alternatively one-third and two-thirds of the seats. Brazil has a multi-party system, with such numerous parties that often no one party has a chance of gaining power alone, and so they must work with each other to form coalition governments.

In the United States, a contingent election is the procedure used to elect the president or vice president in the event that no candidate for one or both of these offices wins an absolute majority of votes in the Electoral College. A presidential contingent election is decided by a special vote of the United States House of Representatives, while a vice-presidential contingent election is decided by a vote of the United States Senate. During a contingent election in the House, each state's delegation casts one en bloc vote to determine the president, rather than a vote from each representative. Senators, on the other hand, cast votes individually for vice president.
