THE POLITICAL PARTIES
------------------------------------------------------------------------------------------

Ideological parties - The third period came with the Second Republic, through national groups with a deep ideological connotation: the National Liberating Alliance and the Brazilian Integralist Action. For the first time, the electoral legislation opened up to the possibility of candidacies presented by parties or by parties' alliances.

With the coup of 1937 and the advent of the Third Republic, Brazil had the only hiatus in the history of its political parties. With the Fourth Republic in 1945, redemocratization made the presentation of candidates exclusive to political parties. In this fourth conformation of the Brazilian parties, there was an explosion of multipartism, with 13 groups.
