The Comparative Constitutions Project (CCP) Database is the most comprehensive, longitudinal collection of constitutional texts and coded provisions for every sovereign state from 1789 to the present, compiled by the Comparative Constitutions Project since 2005.

The datasets are actively maintained and updated yearly.
