Palmyra
Arab caliphates

Palmyra was conquered by the Rashidun Caliphate after its 634 capture by the Muslim general Khalid ibn al-Walid, who took the city on his way to Damascus; an 18-day march by his army through the Syrian Desert from Mesopotamia. By then Palmyra was limited to the Diocletian camp. After the conquest, the city became part of Homs Province.
