In the GDR, the city of Chemnitz had been renamed Karl-Marx-Stadt. An action group was set up to reverse the change in late November 1989, and collected 43,000 signatures as the basis for a referendum. In April 1990, 76% voted for the name Chemnitz. Many people in the GDR began to discover the history of their towns and regions, forming a new identity.
