Khusrau Mirza was the eldest son of the Mughal Emperor Jahangir and his first wife, Shah Begum. The young prince displayed exceptional skills and wisdom and had the privilege to be groomed by the Mughal Emperor (Akbar) himself for the throne of the Mughal Empire. He turned out to be the most capable and qualified son of Jahangir but was befallen by an unfortunate destiny. Being Jahangir's eldest son, he was the heir-apparent to his father but Jahangir favoured his son Khurram Mirza as he held an animosity against Khusrau.

Shah Begum was the first wife and chief consort of Prince Salim. She was known as Zan-i-Kalan being the first wife of Salim. She was a Rajput princess by birth and committed suicide shortly before the succession of her husband to the royal throne. She was the mother of the eldest daughter and son of Prince Salim, Sultan-un-Nissa Begum and Khusrau Mirza.
