Short answers, pulled from the story.
The term subah refers to a province or state within the Mughal Empire. This administrative unit replaced loose feudal arrangements with a rigid, hierarchical system of governance. The word is derived from Arabic and Persian and means a province or state.
Akbar initially carved the empire into twelve distinct subahs in the year 1572. These twelve provinces included Kabul, Lahore, Multan, Delhi, Agra, Avadh, Illahabad, Bihar, Bangal, Malwa, Ajmer, and Gujarat. This system allowed the emperor to collect taxes, raise armies, and administer justice with unprecedented precision.
Shah Jahan expanded the number of subahs to twenty-two during his reign. The city of Agra was renamed Akbarabad in 1629, while Delhi became Shahjahanbad in 1648. The sarkar of Telangana was separated from Berar to become a separate subah during this period.
Aurangzeb added Bijapur in 1686, Sira in 1687, and Golkonda in 1687 to the list of subahs. These southern provinces were the result of prolonged conflicts with the Deccan sultanates. The creation of the subah of Arcot in 1692 further extended the empire's reach into the south.
The term subah is used in the Urdu language to refer to a province of Pakistan. The four provinces of Pakistan are called subah in the Urdu language, a direct legacy of the Mughal administrative system. The word is used in several Pakistani languages, most notably Punjabi, Balochi, and Urdu, to refer to a province of Pakistan.
