Free State of Mecklenburg-Schwerin replaces Grand Duchy of Mecklenburg-Schwerin
The Free State of Mecklenburg-Schwerin (German: Freistaat Mecklenburg-Schwerin) was a state in the Weimar Republic that was established on 14 November 1918 upon the abdication of the Grand Duke of Mecklenburg-Schwerin following the German Revolution. In 1933, after the onset of Nazi rule, it was united with the smaller neighbouring Free State of Mecklenburg-Strelitz to form the new united state of Mecklenburg on 1 January 1934.
