Explanation: The first four years of Akbar’s rule saw the expansion of the Mughal Empire from Kabul to Jaunpur, including Gwalior and Ajmer, under his regent Bairam Khan.

• Soon Bairam Khan began to behave haughtily towards his fellow nobles. Akbar, enraged by his behaviour issued a farman dismissing Bairam Khan.
• Bairam Khan, finally agreeing to submit himself to Akbar, proceeded to Mecca. But on his way, he was murdered by an Afghan.
• The family of Bairam khan was brought to Delhi and his son Abdur Rahim became one of the luminaries of Akbar’s court with the title Khan-e-Khanan.
