Abstract
This chapter examines the main features of the undemocratic regimes that were in power in Latin America from the late 1960s, along with the democratization processes that followed since the 1980s. The nature of the non-democratic governments varied throughout the region, and consequently the types of transition and the quality of the resulting democracy varied as well. The chapter focuses on four cases that reflect these differences: Argentina, Chile, Mexico, and Venezuela. For each country, the chapter reviews a number of dimensions that have been relevant in the democratization processes: the historical and international contexts, the role of economic factors, political culture and society, political parties and social movements, and the institutional challenges that still lie ahead.
