The April 1737 siege of Kandahar began when Nader Shah’s Afsharid army invaded southern Afghanistan to topple the last Hotaki stronghold of Loy Kandahar, which was held by Hussain Hotaki. It took place in the Old Kandahar area of the modern city of Kandahar in Afghanistan and lasted until March 24, 1738, when the Hotaki Afghans were defeated by the Persian army.
