The failing health of the emperor, while it added to the influence of Nūr Jahān over the affairs of state, also increased her apprehension of diminished power if he should die. Of all Jahāngīr's sons Shāh Jahān was most to be feared, as Khusrav though more popular was still a prisoner and untried in public affairs. She now decided to arrange a marriage between Lādlī Begam, her daughter by her former husband, Sher Afgan, and Jahāngīr's youngest surviving son, Shahryār, whose mother had been a concubine, and who was then an immature young man with dissolute inclinations. The formal betrothal took place at Lahore, to be followed by a wedding at Āgra.
