 After the coup d'état that abolished the monarchy and proclaimed Brazil a republic, the system of parliamentary government was not retained.The new republic instead adopted the model of a presidential executive, except for a brief period (September 7, 1961 to January 23, 1963) during the presidency of President João Goulart.The parliamentary system was adopted in 1961 as a compromise solution to a grave political crisis, and was again abolished, this time by plebiscite, in January 1963.
