Mianwali District was an agricultural region with forests during the Indus Valley Civilization. The Vedic period is characterized by Indo-Aryan culture that invaded from Central Asia and settled in Punjab region. In 997 CE, Sultan Mahmud Ghaznavi took over the Ghaznavid dynasty empire established by his father, Sultan Sebuktegin. In 1005 he conquered the Shahis in Kabul, and followed it by the conquests of Punjab region. The Delhi Sultanate and later Mughal Empire ruled the region. The population of the Punjab region became majority Muslim, following the conquests by various Muslim dynasties from Central Asia.
Before the British rule, the area formed an integral portion of the Graeco-Bactrian Empire of Kabul and the Punjab. During British rule, the Indian empire was subdivided into provinces, divisions and districts; afterward, the independence of Pakistan divisions remained the third tier of government until 2000.
