Hans Maier's Collected Works - Volume One. Hans Maier has conducted research and worked across an unusually broad spectrum of disciplines. The history of political science, church and theology history, state thinking, as well as cultural and educational policy and general history are among the areas he has repeatedly returned to. Alongside classics such as "Revolution and Church" or "Older State and Administrative Theory," his foundational contributions have so far only been available in scattered form. A five-volume edition of the "Collected Works" aims to remedy this and make the output of a rich scholarly life more accessible. Hans Maier's now-classic study focuses on the origins of Christian Democratic parties and their intellectual traditions.
