Elisabeth of Brandenburg, Duchess of Pomerania

Elizabeth's father renounced his rights to the succession in Brandenburg and instead received the Franconian possessions of the House of Hohenzollern.

After the death of Otto III, a war erupted between Pomerania and Brandenburg about the inheritance of the Stettin branch of the family.

She felt that her husband had ...planned to kill her, and take her life and limb and, although it would be unchristian and pitiable, revoke her interests and pensions.

For Frederick, the fate of his niece was the motivation to break off negotiations with Wartislaw about Stettin and push through his claims on Pomerania.

After mediation by Duke Henry of Mecklenburg-Stargard, Wartislaw accepted Pomerania as a fief of the Electorate of Brandenburg.
