Administration of the Mughal Empire

Although his fathers rule was generally peaceful, the empire was experiencing challenges by the end of his reign. In 1628, immediately after becoming Mughal Emperor, Shah Jahans forces were ambushed by Sikh rebels, the Emperor organized an assault, which caused almost all the Sikhs, including Guru Hargobind and his mercenaries to flee. Shah Jahan repulsed the Portuguese in Bengal, capturing the Rajput kingdoms of Baglana, Mewar and Bundelkhand to the west and the northwest beyond the Khyber Pass. He then chose his 16 year old son Aurangzeb to serve in his place and subdue the rebellion by the Bundela Rajputs led by the renegade Jhujhar Singh. The Mughal Emperor Shah Jahan then chose his son Aurangzeb to become the Subedar of Deccan and ordered the annexation of Ahmednagar and the overthrow of the Nizam Shahi dynasty.Shah Jahan and his sons captured the city of Kandahar in 1638 from the Safavids, prompting the retaliation of the Persians led by their powerful ruler Abbas II of Persia, who recaptured it in 1649, the Mughal armies were unable to recapture it despite repeated sieges during the MughalSafavid War.

Evidence from the reign of Shah Jahan in the year 1648 states that the army consisted of 911,400 infantry, musketeers, and artillery men, and 185,000 Sowars commanded by princes and nobles and were maintained out of the revenues of the Mughal Empire which amounted to 120,071,876,840 dams. During his reign the Marwari horse was introduced becoming Shah Jahans favorite and various Mughal Cannons were mass produced in the Jaigarh Fort. Under his rule, the empire became a huge military machine and the nobles and their contingents multiplied almost fourfold, as did the demands for more revenue from the peasantry. But due to his measures in the financial and commercial fields, it was a period of general stabilitythe administration was centralised and court affairs systematized.
