The term is usually distinct from chiefs at lower levels, such as village chief (geographically defined) or clan chief (an essentially genealogical notion). The descriptive "tribal" requires an ethno-cultural identity (racial, linguistic, religious etc.) as well as some political (representative, legislative, executive and/or judicial) expression. In certain situations, and especially in a colonial context, the most powerful member of either a confederation or a federation of such tribal, clan or village chiefs would be referred to as a paramount chief. This term has largely fallen out of use, however, and such personages are now often called kings.
