Pope Alexander III (c. 1100/1105 – 30 August 1181), born Roland (Italian: Rolando), was head of the Catholic Church and ruler of the Papal States from 7 September 1159 until his death. A native of Siena, Alexander became pope after a contested election, but had to spend much of his pontificate outside Rome while several rivals, supported by Holy Roman Emperor Frederick I Barbarossa, claimed the papacy. Alexander rejected Byzantine Emperor Manuel I Komnenos' offer to end the East–West Schism, sanctioned the Northern Crusades, and held the Third Council of the Lateran. The city of Alessandria in Piedmont is named after him.
