Amadeo I of Spain vs Ulrika Eleonora

Amadeo I was elected King of Spain by the Cortes after the deposition of Queen Isabella II. He was chosen as a compromise candidate from the Italian House of Savoy, aiming to stabilize the country after the Glorious Revolution.

General Juan Prim, the main political supporter of Amadeo I, was assassinated shortly before the king's arrival. This event deprived Amadeo of his key ally and left him without a strong political base, contributing to the failure of his reign.

Amadeo I arrived in Spain to assume the throne. His reign was immediately challenged by political instability, including opposition from republicans, Carlists, and factions within the monarchy, making his position precarious from the start.

Amadeo I abdicated the Spanish throne, citing the impossibility of ruling due to constant political turmoil and lack of support. His abdication led to the proclamation of the First Spanish Republic, ending the brief Savoyard monarchy.

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.
