The Struggles of King Ferdinand II of León and the Succession Crisis in Castile (1157–1158)

Upon ascending the throne of León in 1157, Ferdinand II faced immediate challenges, both from his powerful nobility and from his elder brother, Sancho III of Castile, who sought to assert dominance over the recently divided kingdom. This period of unrest saw border tensions and internal disputes, as both monarchs maneuvered for influence over the legacy of their father, Emperor Alfonso VII.

The Meeting at Sahagún and Sancho’s Sudden Death (1158)

In an effort to resolve their inheritance disputes, Ferdinand II and Sancho III met at Sahagún in 1158, where they peacefully negotiated a settlement. However, later that same year, Sancho III unexpectedly died, leaving his throne to his young son, Alfonso VIII.

Seizing the opportunity, Ferdinand II occupied parts of Castile, exploiting the instability caused by the child king’s succession. His actions further complicated the fragile political landscape of the Iberian kingdoms, as various factions vied for control over the regency and the future of Castile.
