The Free State of Mecklenburg-Strelitz (German: Freistaat Mecklenburg-Strelitz) was a state of the Weimar Republic established in 1918 following the German Revolution which had overthrown the Grand Duchy of Mecklenburg-Strelitz. The state lasted until the Nazi Party (NSDAP) came to power in Germany and merged the state with the neighbouring Free State of Mecklenburg-Schwerin to form a new united state of Mecklenburg.
