Above the broad range of political parties in Brazilian Congress since there is no election threshold, the Workers' Party (PT), the Brazilian Democratic Movement (MDB), the Brazilian Social Democracy Party (PSDB) and the Democrats (DEM) together control the absolute majority of seats in the Senate and Chamber of Deputies,[1] and effectively have dominated Brazilian political landscape since the return of democracy in 1985. Smaller parties often make alliances with at least one of these four major parties.

Since 1982 Brazilian political parties have been given an electoral number to make it easier for illiterate people to vote. Initially, it was a one-digit number: 1 for PDS, 2 for PDT, 3 for PT, 4 for PTB, and 5 for PMDB. When it became clear that there was going to be more than nine parties, two-digit numbers were assigned, with the first five parties having a "1" added to their former one-digit number (PDS becoming number 11, PDT 12, PT 13, PTB 14, and PMDB 15). Often political parties change their names but retain their number.
