Hisar also known as Hissar is an industrial city, municipal corporation and administrative headquarters of Hisar district of Hisar division in the state of Haryana in northwestern India. It is located 161.2 km (100.16 mi) to the west of New Delhi, India's capital, and has been identified as a counter-magnet city for the National Capital Region to develop as an alternative centre of growth to Delhi. The city was founded in 1354 AD, as Hisar-e-Firoza by Firoz Shah Tughlaq, the Sultan of Delhi from 1351 to 1388. The word Hisar means fort or castle in Persian. The city was ruled by several major powers, including the Tughlaqs in the 14th century, the Mughals in the 16th century, and the British in the 19th century. After India achieved independence, it was unified. Archeological excavations at nearby locations of Rakhigarhi (7000 BCE), Siswal (4000 BCE), and Lohari Ragho suggest the presence of human habitation from pre-Harappan period. Later, Aryan people settled around Drsadvati River. The Jain literature Uttaradhayana Sutra ((599/540 - 527/468 BCE) mentions a town Isukara in the Kuru (c. 1200 – c. 900 BCE) country which is believed to be the earlier name of Hisar. The kingdom of Hisar, with its capital at Agroha, possibly assisted Chandragupta Maurya (reign: 321–297 BCE) in his war against the Greeks. The kingdom was then included in the Mauryan Empire, as evidenced by the discovery of Ashokan pillars in the vicinity of the city. The city later came under the Kushan Empire (127 - 375 CE) and the Gupta Empire (250 - 550 CE). The area was sacked by Mahmud of Ghazni during his campaigns. In the 12th century, the Chauhan king Prithviraj Chauhan made Hansi, located in the present day Hisar district, his capital and built a fort. It remained a strategic place for Chauhan Empire until Prithviraj Chauhan was defeated in the Second Battle of Tarain by the invading Ghurid ruler Muhammad Ghori. Hisar was founded in 1354 AD, as 'Hisar-e-Firoza' by Firoz Shah Tughlaq, who reigned over the Sultanate of Delhi from 1351 to 1388.
