Warfare In December

Zahara  1481  Final Christian Reconquest of Spain

Opening the last Muslim offensive against Christian Spain, Mulei Abdul-Hassan, the new King of Granada, refused the annual tribute to Ferdinand and Isabella and invaded Andalusia. There he surprised and destroyed the fortress of
Zahara, on the Guadalete River, killing or enslaving most of the population. Muslim Spain was finally destroyed in the war that followed (26 December 1481).
