The emergence of political parties from social movements in contemporary Europe and Latin America suggests the enduring importance of two defining features of partisanship: the aim to form a permanent organisation, and the aim to control political institutions from the inside.

This paper examines the significance of these contemporary mobilisations for our larger understanding of the sense and structure of partisanship.
