The article challenges the conceptualization of factionalism in political science. Following a brief review of scholarly contributions in the field, the author argues that the analytical approach based on typologies and categories of subparty groups is not very useful in explaining intra-party behaviour and the process of change because, by their nature, these are static tools. Building on previous contributions to the study of factions, notably Sartori, she suggests focusing on intra-party dynamics instead of on organizational forms of faction. Factionalism should be viewed in non-exclusive terms, i.e. as a dynamic process of subgroup partitioning. It is a multifaceted phenomenon that can transform itself over time in response to incentives. Based on conclusions from case study research of factionalized parties in established democracies, she identifies three main faces of factionalism: cooperative, competitive and degenerative. She suggests that the process of change may occur in a cycle that contributes to party disintegration, as illustrated by the case of the Christian Democratic Party in Italy (DC), which imploded in the mid-1990s under the centrifugal pulls of its factions.
