Mu'ayyid Al-Din Ai-Aba - Establishment of Authority

Establishment of Authority

Ai-Aba had once been a ghulam of the Seljuk Sultan Sanjar, who ruled in Merv. After Sanjar was captured by a band of Ghuzz nomads in 1153 his empire quickly fell into chaos as Ghuzz tribes overran much of the sedentary areas. Sanjar's amirs attempted to restore order by recognizing Suleiman Shah as sultan. Suleiman Shah quickly demonstrated that he was incapable of dealing with the Ghuzz and fled; the amirs then set up the Karakhanid Mahmud Khan in his place, but he did little better.

With the central government unable to restore order on its own, Ai-Aba was free to pursue a largely independent policy in Khurasan. He first drove the Ghuzz out of Nishapur, Tus, Damghan, and several other cities. By lowering taxes and placating the landowners, he was able to build up a good reputation and expand his influence over much of Khurasan. After Mahmud Khan was appointed as sultan, Ai-Aba initially resisted submitting to him; after prolonged negotiations he was convinced to become Mahmud's vassal, although he retained his autonomous rule of the cities he administered.
