Wars were common for this in the British isles were thousands of Catholics and Protestants were killed in wars regarding religion.

Languages and cultures diffuse around the world as peoples migrate and travel from place to place or as the population in one area increases and the area the live in expands. Languages move as people move and they are adopted and shared amongst new groups of people as human migration patterns shift and evolve.
