The aim of this paper is to analyse the organizational model of one of the most successful European radical left parties, the Greek Coalition of the Radical Left (SYRIZA). Our goal is to analyse SYRIZA’s organizational transition from the electoral arena to the government (2015). Our main finding is that SYRIZA started as a socially-oriented organization led by an oligarchic dominant coalition and converted itself into a political party, characterized by a prevailing role of the party in public office/party government. Both the institutional environment and the party organization’s first configuration have had an impact on this change.

This article examines the political transformations experienced by the Communist Party and the evolution of the radical left in France in the twenty-five years after 1989. Interpreting the Communist Party and Left Front as anti-establishment, that is, opposed to the political elite, but pro-system parties that are not interested in changing the nature of democratic governance. The peculiarities of French communism and its political philosophy are illustrated. Finally, this study considers the constituent process of the Front. At the beginning of the 21st century, the Front plays the role of a political federation to the left of the Socialist Party with positive electoral results.
