This volume addresses the political traditions that flourished in regions traditionally neglected by Atlantic history, but which are nevertheless indispensable for a comprehensive interpretation of political modernity. The history of political liberty simply cannot be reconstructed without taking into account the role of the Atlantic as a space for the circulation of ideas. The different chapters trace the origins of the Atlantic notions of liberty in the crisis of the colonial world, in the diverse processes that led to independence from the metropolis, and in the subsequent efforts to build a constitutional order. The book takes an innovative approach by putting together experiences of the English, Portuguese, and Spanish Atlantic and by dealing with political ideas as discursive and socially embedded practices.
