Garcia I of Leon vs Wenceslaus IV of Bohemia

Upon the deposition of his father Alfonso III, Garcia I became the first king of Leon, ruling the central portion of the divided Asturian kingdom. He established his court in the city of Leon, which became the capital of the new kingdom, marking the transition from Asturias to Leon as the dominant Christian power.

Garcia I continued the repopulation of the Duero Valley, granting land and privileges to settlers from the north. He established fortified settlements at Roa, Osma, and San Esteban de Gormaz, strengthening the Leonese frontier against Muslim raids and consolidating control over the region.

Garcia I died without a legitimate heir, leading to a succession crisis. The throne passed to his brother Ordo

Wenceslaus IV initially supported Jan Hus and the reform movement, but later opposed them under pressure from the Catholic Church. His inconsistent policies alienated both Hussites and Catholics, weakening his authority.

Wenceslaus IV's refusal to release Hussite prisoners led to a mob storming the New Town Hall in Prague. The crowd threw the city councillors out of a window, triggering the Hussite Wars that would devastate Bohemia for decades.

Wenceslaus IV died of a heart attack shortly after the Defenestration of Prague. His death left Bohemia without a strong ruler, allowing the Hussite movement to gain momentum and plunging the kingdom into civil war.
