Political theology is a term which has been used in discussion of the ways in which theological concepts or ways of thinking relate to politics. The term is often used to denote religious thought about political principled questions. Scholars such as Carl Schmitt, a prominent Nazi jurist and political theorist, who wrote extensively on how to effectively wield political power, used it to denote religious concepts that were secularized and thus became key political concepts. It has often been affiliated with Christianity, but since the 21st century, it has more recently been discussed with relation to other religions.
