Abstract
Several dozen ethnoregional parties have been active in industrial democracies since the late 1960s. The most successful of these are examined to understand what determines their ideological characteristics, how these characteristics correlate with electoral success and policy success and what ideological trends are emerging among newer ethnoregional parties. This is done by analysing the ideologies of these parties as functions of their positions on the restructuring of the‐ state and socio‐economic issues. This analysis is then used to examine successful ethnoregional parties that emerged in the late 1960s, 1970s and early 1980s and now in the 1990s.
