[2]: 410 Upon his enthronement, Humayun appointed Mahmud Gawan lieutenant of the kingdom and governor of Bijapur, ennobling him with the title of Malik-ut-Tujjar.
Still dissatisfied by the appointment, he began a rebellion, supported by his father Jalal Khan and local Velama chiefs.
Humayun proceeded to meet the rebels, and offered terms of peace to Sikandar, which were refused.
It is at this time that the cruel punishments of Humayun were described—Hasan Khan was thrown before a tiger, which proceeded to maul and devour him, while some of his followers were cast into boiling cauldrons.
According to legend, the tomb split open when Humayun's body was interred, thus signifying that god refused protection for his remains.
According to modern scholars such as Haroon Khan Sherwani and Ghulam Yazdani, the accounts of Humayun's cruelty have been exaggerated.
