How far did the Umayyad empire extend at its greatest size?

At its greatest extent, the Umayyad dynasty ruled a vast empire that stretched from the Iberian Peninsula in the west to the borders of India in the east.12

The empire's expansion included the following regions:

• West: The Umayyads spread across the northern coast of Africa and occupied much of Spain.12
• East: The empire extended into Khorasan, Turkistan, and northwestern India.13
• North: Military campaigns were carried out against the Byzantine Empire in Asia Minor.1

The empire reached the limits of its expansion during the reign of Hishām ibn ʿAbd al-Malik, as further advances were halted in France following the Battle of Tours in 732 and by military defeats in Anatolia in 740.3
