Шамсуддин
When Qutb al-Din died in February 1419 the Mihrabanids and the amirs of Sistan decided to proclaim Shams al-Din as his successor. Shams al-Din traveled to Shah Rukh's court and was confirmed as malik of Sistan. In 1420 the Timurid summoned him to assist in a campaign against the Qara Qoyunlu Turkmen. Shah Rukh defeated the army of the Turkmen leader Qara Iskander and occupied Azerbaijan and Armenia in 1421. Shams al-Din was named governor of Tabriz, a post which he held for two years.
