During his 50-year reign, Akbar accumulated much wealth from the political and commercial centers in northern India. His immediate successors, Jahangir and Shah Jahan, were able to surround themselves with a splendor and opulence unequaled by any other Muslim dynasty.
From the beginning, Jahangir's life was overshadowed by the achievements of his father Akbar. Jahangir grew up resentful of his masterful parents and bitterly jealous of his father's long-established coterie of advisers who must have interfered between father and son. Hambly writes that despite Jahangir's acute intelligence, the Mughal ruler was generally indifferent to the larger interests of the empire. Moreover, he lacked any obvious inclination for warfare and was bored by the humdrum details of day-to-day administration. Jahangir was self-indulgent and sensual with a streak of cruelty that emanated from a weak personality.
Despite Jahangir's disinterest in expansion, the imperial frontiers continued to move forward -- in Bengal, Mewar and Ahamadnagar. The only major reversal to the expansion came in 1622 when Shah Abbas, the Safavid ruler of Iran, captured Kandahar with impunity. Jahangir lived under the spell of personalities that were more colorful than his own; the most influential of these personalities was the beautiful Nur Jahan whom he married in 1611. Nur Jahan then became the real ruler of the empire until the death of her husband Jahangir.
