Abaqa Khan
Relations with the Ilkhanids had not significantly improved since the siege of Shahr-i Sistan, and in 1276 or 1277 Abaqa Khan sent an army to invade Sistan. The Ilkhanids caused havoc in the countryside but an advance on the capital was defeated by the Mihrabanid army. The breach with the Ilkhanate was somewhat mended after Ahmed Tekuder's ascension in 1282; the ilkhan sent Nasir al-Din a "yarligh" and other insignia as a confirmation of his rule.
