Saladin
From Tardis Wiki, the free Doctor Who reference
Saladin was a Saracen Sultan of Egypt and Syria and military leader during the Crusades. One of his brothers was Saphadin.
He had a reputation as a democratic man, and the First Doctor had always wanted to meet him, though he was not afforded the opportunity of doing so during his visit to Palestine in 1190. (TV: The Crusade)
