A Subah is a term for a province or state in several South Asian languages. It was introduced by the Mughal Empire to refer to its subdivisions or provinces; and was also adopted by other polities of the Indian subcontinent. The word is derived from Arabic and Persian. The governor/ruler of a Subah was known as a subahdar (sometimes also referred to as a "Subeh"[1]), which later became subedar to refer to an officer in the Indian and Pakistani armies. The subahs were established by Padishah (emperor) Akbar during his administrative reforms of the years 1572–1580; initially, they numbered 12, but his conquests expanded the number of subahs to 15 by the end of his reign. Subahs were divided into Sarkars, or districts. Sarkars were further divided into Parganas or Mahals. His successors, most notably Aurangzeb, expanded the number of subahs further through their conquests. As the empire began to dissolve in the early 18th century, many subahs became de facto independent or came under the influence of the Marathas or the suzerainty of the East India Company.
In the modern context, subah (صوبہ) is used in several Pakistani languages (most notably Punjabi, Balochi, and Urdu) to refer to a province of Pakistan.
