Over the past several decades, the Dominican Republic has experienced striking political stagnation in spite of dramatic socioeconomic transformations. In this work, Jonathan Hartlyn offers a new explanation for the country's political evolution, based on a broad comparative perspective. Hartlyn rejects cultural explanations unduly focused on legacies from the Spanish colonial era and structural explanations excessively centered on the lack of national autonomy. Instead, he highlights the independent impact of political and institutional factors and historical legacies, while also considering changes in Dominican society and the influence of the United States and other international forces.
