Prime Minister of Brazil  Historically, the political post of Prime Minister, officially called President of the Council of Ministers, existed in Brazil in two different periods: from 1847 to 1889 (during the Empire) and from 1961 to 1963 (under the Fourth Republic). The parliamentary system was first introduced in the country in 1847 by Emperor Pedro II and maintained until the abolition of the monarchy in 1889. The system was briefly restored during the tenure of President João Goulart between 1961 and 1963, after a constitutional amendment approved by his opponents before the beginning of his term created the post; it was abolished with a plebiscite. Below are more detailed descriptions of the post in each period. The political position of Prime Minister of Brazil was first created in 1847 by the Brazilian Emperor Pedro II officially as President of the Council of Ministers, but he was referred to by the press and the people as "President of the Cabinet". Often, the title "President of the Council", a shortened version of the official style, was also employed. The written Constitution of the Brazilian Empire did not require the Emperor to appoint a prime minister; nor did it provide for a parliamentary system of government, instead vesting the Executive authority in the Emperor himself, and stipulating that the Emperor was to be aided by ministers that he was free to appoint and dismiss. However, Emperor Pedro II decided to appoint a president of the Council among his ministers, to lead the workings of the Government. He also chose to create a sort of parliamentary government, whereby the prime minister would be someone who could command a majority in the Chamber of Deputies, the lower House of the Brazilian Imperial Parliament, known as General Assembly. Therefore, even without being required by the Constitution, the Emperor started to exercise his authority in a manner compatible with parliamentary government, only appointing as prime minister someone who could retain parliamentary support, etc. However, the emperor was not a figurehead monarch like other heads of State in a parliamentary system. The prime minister needed to retain the political confidence both of a majority of the Chamber of Deputies and of the Emperor, who actively scrutinized the workings of the Government. Sometimes the Emperor would dissolve the Chamber of Deputies and summon new elections (a power he possessed under the Constitution), or dismiss the prime minister, due to his own political beliefs about the efficiency of the Government. Thus, the Emperor would often dismiss a prime minister, and then appoint someone else from the same party. All this led to a succession of short-lived Cabinets. The emperor retained decision-making powers with regard to the signature or veto of bills passed by Parliament, and would not always abide by the advice of his ministers.
