Sabzevār
Sabzevār was a city in western Khorasan. In 1337 the local ruler 'Ala' al-Din Muhammad held it for the Il-Khanid claimant Togha Temür, but his taxation provoked revolt.
In 1337 'Abd al-Razzaq killed a tax official and seized the city, making it the capital of the Sarbadars. Their leader Yahya Karawi murdered Togha Temür in 1353. 'Ali Mu'ayyad submitted to Timur in 1381, and Sabzevār supplied his armies. Later the Uzbeks seized the province from the Safavids, who recovered it around 1600.
