An ethnoreligious group (or an ethno-religious group), or simply an ethnoreligion, is a grouping of people who are unified by a common religious and ethnic background.
This article is about groups that share both an ethnic and a religious background. For religions that are closely tied to a particular ethnic group, see ethnic religion.
Ethnic group whose members are also unified by a common religious background
Furthermore, the term ethno-religious group, along with ethno-regional and ethno-linguistic groups, is a sub-category of ethnicity and is used as evidence of belief in a common culture and ancestry.
In a narrower sense, they refer to groups whose religious and ethnic traditions are historically linked.
