In 712, Arab Muslim general Muhammad bin Qasim conquered most of the Indus region in modern-day Pakistan for the Umayyad Empire, incorporating it as the "As-Sindh" province with its capital at Al-Mansurah, 72 km (45 mi) north of modern Hyderabad in Sindh, Pakistan. After several incursions, the Hindu kings east of Indus defeated the Arabs at the Battle of Rajasthan, halting their expansion and containing them at Sindh in Pakistan. The south Indian Chalukya empire under Vikramaditya II, Nagabhata I of the Pratihara dynasty and Bappa Rawal of the Guhilot dynasty repulsed the Arab invaders in the early 8th century.
Is there an answer to this question (If it cannot be answered, say "unanswerable"): When was the Arab invasion repulsed?
early 8th century
