After the establishment of the Delhi Sultanate, Multan became its western frontier. In the beginning it was governed by Nasir_ud_Din Qabacha, then captured by jaial_al_Din Manakabarni and finally annexed by Shams_ud_Din Altamash. Altamash was the first king to appoint a woman as his official successor.
Altamash was a shrewd and intelligent man. He quickly realized that, if anything was to be saved of the Turkish possessions in India, he would have to strengthen the Sultanate and prevent the Turkish nobles from breaking away and carving out independent domains for themselves.
So Altamash sent Jalal-ud-din an extremely courteous letter saying that he, Altamash, would have been more than happy to give him, the Shah, shelter but very much feared that the harsh Indian summer would not suit His Excellency, so he begged to be excused of the honor of being his host.
Altamash was also the first Muslim ruler to lay down a basic administrative system to rule his scattered territories, complete with proper revenue and finance departments, district (iqta) divisions, local police systems and the works.
