Explanation:

In December 1530, Humayun succeeded his father to the throne of Delhi as ruler of the Mughal territories in the Indian subcontinent. Humayun was an inexperienced ruler when he came to power, at the age of 22. His half-brother Kamran Mirza inherited Kabul and Kandahar, the northernmost parts of their father's empire. Kamran was to become a bitter rival of Humayun.

Shortly after Humayun had marched on Gujarat, Sher Shah Suri saw an opportunity to wrest control of Agra from the Mughals. He began to gather his army together hoping for a rapid and decisive siege of the Mughal capital. Upon hearing this alarming news, Humayun quickly marched his troops back to Agra allowing Bahadur to easily regain control of the territories Humayun had recently taken. In February 1537, however, Bahadur was killed when a botched plan to kidnap the Portuguese viceroy ended in a fire-fight that the Sultan lost.
