However, it is possible to have considerable confidence regarding the location of an urheimat of a language or language family from multiple lines of linguistic, genetic and archaeological evidence, even when the precise contours of a proto-language are not firmly established.

In the latter part of the twentieth century, the link between archaeological cultures and language boundaries was weakened by the discovery of cases in which language shifts occurred with only minor differences in cultural artifacts.

This article summarizes some of the leading, and sometimes competing, urheimat proposals for some of the larger or more carefully studied language families.

A proto-language is a hypothetical parent language in the tree model of language evolution.

This culture history theory, developed by Gustaf Kossinna, formalized the presumption that unified ethnicities, such as peoples or tribes, could be associated with archaeological cultures.
