The Mughal-Safavid War of 1649-53 was fought between the Mughal and Safavid empires in the territory of modern Afghanistan. The war began after a Persian army, while the Mughals were at war with the Janid Uzbeks, captured the fortress city of Kandahar and other strategic cities that controlled the region. Shah Jahan sent Aurangzeb with 50,000 soldiers to recapture it, but although he defeated the Safavids outside the city he was unable to take it. He attempted to take the fortress city again in 1652. After two months of fighting Persian resistance and the growing activities of the Uzbeks, Aurangzeb was forced to abandon the campaign. In 1653 Shah Jahan sent his favorite son, Dara Shikoh, with a large army and two of the heaviest artillery pieces of the empire, but after a 5 month siege the Mughals couldn't manage to starve the city, and the attempt to breach their walls by cannon fire also failed. The Mughals finally gave up all attempts to recover Kandahar. The Mughal-Persian Wars were a series of wars fought in the 17th and 18th centuries between the Safavid and Afsharid Empires of Persia, and the Mughal Empire, over what is now Afghanistan. Most of the conflict between the two powers were limited to battles for control over Kandahar.
