Professor Jason Mazzone has published Comparative Constitutional History: Principles, Developments, Challenges (Brill, July 2020) along with co-editors Francesco Biagi and Justin O. Frosini. 

The book is the first in a series, with each volume emerging from a conference on Constitutional History: Comparative Perspectives that is sponsored by the Illinois Law Program on Constitutional Theory, History and Law along with the University of Bologna and Johns Hopkins University. 

The book abstract follows:

While comparative constitutional law is a well-established field, less attention has been paid so far to the comparative dimension of constitutional history. The present volume, edited by Francesco Biagi, Justin O. Frosini and Jason Mazzone, aims to address this shortcoming by bringing focus to comparative constitutional history, which holds considerable promise for engaging and innovative work along several key avenues of inquiry. The essays contained in this volume focus on the origins and design of constitutional governments and the sources that have impacted the ways in which constitutional systems began and developed, the evolution of the principle of separation of powers among branches of government, as well as the origins, role and function of constitutional and supreme courts.
