Voluntary cultural death
Loss of cultural identity
Death of cultural soul
When a people begins to ignore its own culture and neglect its language, accepting the invasion of some foreign language, and when its leading scientists and writers start to publish the products of their intellect in foreign languages and not in their own, then the people in question is on the road to the destruction of its own culture, or cultural suicide.
It was claimed by a former chancellor of Germany in 1992 that the soul of the German people was in danger with the problem of violence against foreigners.
The most immediate tragedy of loss of knowledge and traditions is for the people themselves. They do not always die out, but the soul of their culture withers away. Often left behind are people who are shadows of what they once were, and shadows of the dominant, homogenous culture which has supplanted them.
