Answer
Toledo, the capital of the Taifa of Toledo, fell to Alfonso VI, King of León and Castile, in 1085 after a prolonged siege. The city's capture was a significant triumph, expanding Alfonso's domain into the heart of Muslim-ruled Al-Andalus and giving him control over a region of great political, economic, and cultural importance. This victory earned Alfonso the epithet "victoriosissimo rege" (most victorious king).
