The Comparative Constitutions Project is an academic study of the content of the world's constitutions from 1789 to 2022, with yearly updates. The project was founded by Zachary Elkins and Tom Ginsburg in 2005 when they were colleagues at the University of Illinois and fellows at the Cline Center for Advanced Social Research.[1] The primary objective of the project is to understand the origins and consequences of constitutional choices.[2] Most of the seed money for the project came from the Cline Center, as well as two successive grants from the National Science Foundation.[3][4] James Melton, a graduate student at Illinois, joined Elkins and Ginsburg as a full collaborator before leaving academia in 2015. The project continues to be administered by Elkins and Ginsburg as a collaboration between the University of Texas and the University of Chicago, where they are based, respectively.[5][6]
