His administrative reforms were also important. They were aimed to increase the control of Sultan over the nobles and provinces. Royal officers were appointed in each province for this purpose. Most of the forts were under the control of these officers. Allowances were reduced to the nobles who shirked their responsibility. This was disliked by the nobles. So, the Deccani nobles organised a plot against Gawan. They induced the Sultan to punish him with death sentence. After the execution of Gawan, the Bahmani kingdom began to decline. Muhammad Shah was succeeded by weak Sultans.

During this period the provincial governors declared their independence. By the year 1526, the Bahmani kingdom had disintegrated into five independent sultanates. They were Ahmadnagar, Bijapur, Berar, Golkonda and Bidar and known as Deccan Sultanates.
