Qandahar was one of the most important strategic outposts on the frontier near Hindukush mountains. The political and diplomatic relations between Mughals and their neighbouring empires like the Safavid empire hinged on the control of Qandahar. This way Qandahar remained a bone of contention between the Mughals and Safavids. The town was initially under control of Humayun, which was reconquered by Akbar in 1595. Despite being under Mughal control Safavids continued to stake claims to Qandahar and in 1622 a Persian army besieged the city and defeated the Mughal garrison stationed there.
