Ulrika Eleonora

Ulrika Eleonora was crowned Queen of Sweden after the death of her brother Charles XII. Her coronation was conditional on accepting a new constitution that limited royal power, marking the start of the Age of Liberty.

Ulrika Eleonora abdicated the throne in favor of her husband, Frederick I, after only one year as queen. She did so to allow him to become king, as she had no children and the Riksdag preferred a male monarch.

As queen, Ulrika Eleonora oversaw the conclusion of the Great Northern War with the Treaty of Nystad. Sweden ceded Livonia, Estonia, and Ingria to Russia, ending its status as a major European power.

Ulrika Eleonora died in Stockholm at age 53. Her death ended the life of Sweden's only reigning queen regnant, who had abdicated after a brief reign.
