The Caucasus region is characterized by highly diverse linguistic, ethnic, cultural and religious traditions, depending on geography and socio-historical contexts. This edited volume explores this diversity over the centuries, both in its historically plural forms of religion and its locally specific transformation processes. In antiquity local religious practices were already shaped by influences from the Ancient Near East, Iran and Greece; the Christianized and Islamized regions of the Caucasus as well as Jewish groups are also characterized by their own independent development. The pluralism in religious traditions also characterizes the religious policies of the post-Soviet states of Armenia, Azerbaijan and Georgia.
