Though the Safavids had established control over Basra, they refrained from laying "full and definitive claim" to the city.[10] Sultan Husayn's government was still concerned not to disrupt the peace with the Ottomans. Furthermore, they were aware of Iran's military weakness at the time and realized it would be "difficult to hold on to a city located in an extremely volatile region".[2] The activities of the Kurdish rebel Suleiman Baba, who had captured the town of Ardalan and the fortress of Urmia near the Ottoman border in the same year, reinforced their concerns.[10] In late 1697, Shaykh Mane, having made peace with his former enemy Farajollah Khan,[lower-alpha 3] and assisted by Moshasha defectors, defeated a large Safavid force near the fortress of Khurma (Khorma) and captured their general. This forced Sultan Husayn to offer the Basra to the Ottomans.[2][10] Sultan Husayn had keys made of pure gold and sent Rostam Khan Zanganeh as ambassador to Constantinople, to hand them over to the Ottoman Sultan Mustafa II (r. 1695–1703), in a symbolic gesture offering the city to Ottoman control.[10] However, although the Safavids continued showing a willingness to return Basra to the Ottomans and entertained an Ottoman embassy in Isfahan between December 1698 and April 1699, Basra would stay in Safavid hands until 1701.[2][lower-alpha 4]
