When Akbar died, Prince Salim succeeded with the title Jahangir (Conqueror of World) in 1605. Jahangir's rule witnessed a spate of rebellions. His son Khusrau revolted but was defeated and imprisoned. One of his supporters, Guru Arjun, the fifth Sikh Guru, was beheaded.
In 1611, Jahangir married Mehrunnisa who was known as Nur Jahan (Light of World). Her father Itimaduddauala was a respectable person. He was given the post of chief diwan. Other members of her family also benefited from this alliance. Nur Jahan's elder brother Asaf Khan was appointed as Khan-i-Saman, a post reserved for the nobles. In 1612, Asaf Khan's daughter, Arjumand Banu Begum (later known as Mumtaj), married Jahangir's third son, prince Khurram (later Shah Jahan).
It was believed by some historians that Nur Jahan formed a group of 'junta' and this led to two factions in the Mughal court.
This drove Shah Jahan into rebellion against his father in 1622, since he felt that Jahangir was completely under Nur Jahan's influence. However, this view is not accepted by some other historians. Till Jahangir became weak due to ill health, he only took important political decisions. It is revealed from his autobiography.
However, it is clear that Nur Jahan dominated the royal household and set new fashions based on Persian traditions. She encouraged Persian art and culture in the court. She was a constant companion of Jahangir and even joined him in his hunting.
The rise of Shah Jahan was due to his personal
ambitions. He rose in revolt against his father who ordered him to go to
Kandahar. This rebellion distracted the activities of the empire for four
years. After Jahangir's death in 1627, Shah Jahan reached Agra with the support
of the nobles and the army. Nur Jahan was given a pension and lived a retired
life till her death eighteen years later.
