In the parliamentary field, apart from the main parties - Liberal and People's Party - there were plenty of other groups and parties active. The dissolution of groups inspired by Venizelism led to the formation of the Republic Union under Alexandros Papanastasiou, who occupied the left wing, of Progressive Liberals under Georgios Kaphantaris, and the Conservative Democrats under Andreas Michalakopoulos. In the People's Party, Panayis Tsaldaris was elected leader. At the same time other anti-Venizelist formations were on the march, such as the 'Freethinkers' of Ioannis Metaxas and the National Radical Party of Georgios Kondylis. These coalitions were accompanied by a number of other - usually short-lived - factions.

As party policies did not contribute to the maintainance of social cohesion, the 'exceptional' capacities of the leader were among the basic criteria of choice that the electoral body had. In the field of the ensuing ideological transformations, which were mainly the result of social agitations, what is of special interest is the strong anti-royalism demonstrated by a considerable part of Venizelism (during the 1920s) and the Communist party with its total opposition to the 'bourgeois' parliamentary system.
