Joanna Sophia of Bavaria

Joanna Sophia of Bavaria, born in 1373, was the youngest daughter of Albert I, Duke of Bavaria, and his first wife, Margaret of Brieg. A member of the illustrious House of Wittelsbach, her life was marked by significant political alliances and familial ties.

On June 13, 1395, Joanna Sophia entered into a strategic marriage with Albert IV, Duke of Austria, in Vienna. This union not only solidified their families' connections but also brought an end to the longstanding feud between their fathers. As part of the agreement, Joanna Sophia's father consented to pay ten thousand Pfennige and transferred the fortress of Natternberg along with the town of Deggendorf to Albert III of Austria.

The couple had two children who both reached adulthood: Albert V, born on August 16, 1397, and Margaret, born on June 26, 1395. Margaret later married Duke Henry XVI of Bavaria in Landshut on November 25, 1412, following Joanna Sophia's death. Albert V would marry Elizabeth of Luxembourg, the only child of Emperor Sigismund.

Throughout her life, Joanna Sophia navigated the complexities of court politics, often dealing with conflicts involving her husband and her brother-in-law, Wenceslaus, King of the Romans, as well as Sigismund, Holy Roman Emperor. These tensions persisted until Albert's death in 1404, after which Joanna Sophia took on the role of arranging advantageous marriages for her children.

Joanna Sophia passed away at the age of thirty-six or thirty-seven in Vienna, leaving behind a legacy intertwined with the political landscape of her time.
