Is economic development conducive to political democracy? Does democracy foster or hinder material welfare? These two questions are examined by looking at the experiences of 135 countries between 1950 and 1990. Descriptive information, statistical analyses, and historical narratives are interwoven to gain an understanding of the dynamic of political regimes and their impact on economic development. The often surprising findings dispel any notion of a tradeoff between democracy and development. Economic development does not generate democracies, but democracies are much more likely to survive in wealthy societies.
