Hisar

Hisar was founded in 1354 by Firuz Shah Tughlaq, Sultan of Delhi, as Hisar-e-Firoza, the Fort of Firuz. Its walls enclosed a palace complex with halls, a mosque and underground chambers, while four gates opened onto the surrounding plain. The sultan also built the Gujri Mahal near his palace. Hisar became a center of authority on the western approaches to Delhi, but its fort was burned by Timur's soldiers during his invasion in 1398.

Babur rewarded his son Humayun with Hisar after a successful campaign against Ibrahim Lodi. Sher Shah Suri took it in 1540, and Humayun recovered it in 1555 before assigning it to Akbar. In 1798 the Irish soldier George Thomas occupied Hisar as part of a territory ruled from Hansi; he was driven out in 1801. The East India Company's authority reached the region in 1803, and Hisar later replaced Hansi as the district headquarters in 1832.
