Political Cleavage Analysis

The freezing hypothesis is Lipset and Rokkan's claim that the cleavage structures which crystallized at the time of mass enfranchisement in the early twentieth century became 'frozen' into party systems and persisted with remarkable stability for decades afterward. In their famous formulation, the party systems of the 1960s reflected, with few exceptions, the cleavage structures of the 1920s. The hypothesis explains the long-run continuity of Western party systems and has served as the benchmark for subsequent debates about dealignment, volatility, and the rise of new parties that appear to challenge that stability.

Following the refinement by Bartolini and Mair, a full cleavage comprises three elements. First, an empirical or structural element: an objective social division such as class, religion, or region. Second, a normative or identity element: a sense of collective identity and belonging among those on each side of the division. Third, an organizational or behavioral element: institutions — parties, unions, churches — that give the division stable expression and channel it into political action. A demographic difference that lacks shared identity and organizational anchoring is not, on this account, a genuine cleavage.

Partly. The owner-worker (class) and state-church (religious) cleavages remain visible but have weakened in many democracies through dealignment, and the land-industry and center-periphery cleavages persist mainly in particular national contexts. At the same time, scholars argue that new cleavages have emerged on top of the classic ones: a materialist-postmaterialist value divide identified by Inglehart, and more recently a globalization or transnational cleavage over immigration, integration, and cultural identity. Cleavage analysis remains the framework within which these continuities and transformations are debated.
