Duchy of Mecklenburg

The state was formed in 1471, when duke Henry IV, had united the duchies of Mecklenburg-Stargard and Mecklenburg-Schwerin. The state existed until 7 May 1520, when it was partitioned into the duchies of Mecklenburg-Güstrow and Mecklenburg-Schwerin. It was again reestablished in 1695, with the unification of Mecklenburg-Güstrow and Mecklenburg-Schwerin. Frederick William became the duke. In 1701, it was partitioned into the duchies of Mecklenburg-Schwerin and Mecklenburg-Strelitz.
