Ethnic religions (also "indigenous religions" or "ethnoreligions") are generally defined as religions which are related to a particular ethnic group (ethnoreligious group), and often seen as a defining part of that ethnicity's culture, language, and customs (social norms, conventions, traditions). In an ethnic religion, the ethnic group and its beliefs system cannot be easily separated. Oftentimes an ethnic religion's doctrine only pertains or is directed to that group. Many modern ethnic religions accept converts, but do not seek converts, as opposed to universal religions, which are open to all peoples and actively pursue and accept converts.
