governor of Gujarat became independent in about 1403. Muhammad Shah was the first Sultan.
He was, however, put to death by his father Zaffarkhan who stepped in his place as
Muzzafar Shah. He, in his turn, was poisoned by his grandson, Ahmed Shah, in or about
1411. Ahmed Shah transferred the capital from Anahilavada Patan to Karnavati which he
named Ahmedabad in 1413.4
Ahmed Shah took to a rigorous campaign of converting Hindus to Islam. Many petty chiefs,
till then independent, accepted Islam and agreed to pay a regular tribute.
