Ferdinand III of Castile vs Tokhta

Ferdinand III inherited the Kingdom of Castile from his mother and the Kingdom of Leon from his father, permanently uniting the two crowns. This union created the largest Christian kingdom in Iberia and strengthened the Reconquista.

Ferdinand III captured the city of Cordoba, the former capital of the Umayyad Caliphate, after a long siege. The conquest brought the Great Mosque of Cordoba under Christian control and was a major symbolic victory in the Reconquista.

Ferdinand III besieged and captured Seville, the largest city in Moorish Iberia, with the aid of a Castilian fleet. The conquest gave Castile control of the Guadalquivir River and a major port for trade and naval operations.

Tokhta reasserted the authority of the central khan over the Golden Horde, suppressing rebellious emirs and consolidating power. He reorganized the administration and restored the capital at Sarai, ending a period of fragmentation.

Tokhta led a military campaign against the Nogai Horde, a breakaway faction that had challenged his authority. The campaign culminated in the defeat and death of Nogai, the leader of the Horde, restoring Tokhta's control over the western territories of the Golden Horde.

Tokhta ordered the expulsion of Genoese merchants from the Crimean port of Caffa, leading to a military conflict. The Genoese were defeated, and their trading privileges were revoked, strengthening the Golden Horde's control over the Black Sea trade.
