The Historical Left was led by the Prime Minister of Italy, Agostino Depretis, longtime Prime Minister of Italy.

The bloc of the Historical Right was led by Marco Minghetti, a conservative politician and former Prime Minister, from Bologna.

A third large parliamentary group was the Dissident Left, composed by former members of the Left, which were against the alliance with the Right. Also known as La Pentarchia (The Pentarchy), its main leader was Giuseppe Zanardelli, a jurisconsult from Brescia.
