Jund Filastin
Palestine was conquered by the Islamic Caliphate, beginning in 634 CE. In 636, the Battle of Yarmouk during the Muslim conquest of the Levant marked the start of Muslim hegemony over the region, which became known as Jund Filastin within the province of Bilâd al-Shâm (Greater Syria). In 661, with the Assassination of Ali, Muawiyah I became the Caliph of the Islamic world after being crowned in Jerusalem. The Dome of the Rock, completed in 691, was the world's first great work of Islamic architecture.
