Since the 1960s, new left-socialist or ecology parties have appeared in approximately half of the advanced Western democracies. These parties have a common set of egalitarian and libertarian tenets and appeal to younger, educated voters. The author uses macropolitical and economic data to explain the electoral success of these left-libertarian parties. While high levels of economic development are favorable preconditions for their emergence, they are best explained in terms of domestic political opportunity structures. There is little evidence that these parties are a reaction to economic and social crises in advanced democracies. The findings suggest that the rise of left-libertarian parties is the result of a new cleavage mobilized in democratic party systems rather than of transient protest.
