The Reishahr rebellion of 1539–1540 (or the Siege of Reyshahr) was a revolt led by Hasan Sultan and his brother Shah Ali following the Portuguese expeditions to Reishahr. It was suppressed after a long land siege by the Safavids, made decisive by a Portuguese naval blockade, resulting in Reishahr's capitulation and loss of autonomy.
