Rohtak is the sixth most populous city in Haryana as per the 2011 census with population of 374,292 and has literacy rate of 84.08.
It is believed that the city's name is of Indo-Aryan origin and is recorded in the Vedas. It was founded by the Vedic people, and was named Rohtashgarh. Many aryans migrate in this city. The Jats & Rajputs of Rohtak under the leadership of Khokhar, attacked Mahmud Gaznavi and also accompanied Khokhar Jats in 1206 AD against Mohmad Gouri. Subsequently the evolution of the named is traced as "Rohītaka-kula > Rohitaka > Rohtak" and Michael Witzel notes that this accords with the place existing around 500 BC. The same source also suggests that the name may have derived from the tree Rohitaka as well, a tree well known in the area for its superb timber.
The ruins of the ancient town at Khokrakot suggest that perhaps the town is as old as Indus valley Civilization as the Minar finds at Khokhrakot are typical of Indus Valley sites. It is also identified with Rohitika, a place mentioned in the Mahabharata It was quite possibly the capital of Bahudhanyaka, the kingdom of Yaudheyas. In the Vinaya of the Mulasarvasti-vadins, Jivaka is represented as taking journey from Taxila in the north west of Bhadramkara, Udumbasa, Rohitaka and Nathura in the Ganga Doab. The ancient highway carried the trade of the ganga valley to Taxila passing through Rohitika to Sakala. The existence of the town during the rule of Kushan is testified by the recovery of Khushana Pillar Capital decorated with carving of winged lions and riders. An example of a lion capital of the 1st or 2nd century AD, it resembles the lion capital in the British museum at London, well known for its inscriptions. The riders on it are similar to the riders on elephant at Karle cave and figures at Sanchi Gateway. It is a significant example of the sculptural art of Haryana towards the beginning of the Christian era. Clay mounds of coins discovered at Khokhrakot have thrown important light on the process of casting coins in ancient India. The coin moulds of the later Yadhyayas of the 3rd or 4th century AD have been discovered in large number here of the same and subsequent dates are several clay sealings. A Gupta terracotta plaque and a head of later date have also been discovered. The town continued to flourish till the 10th century AD as coins of Samanta Deva, the Hindu King of Kabul have been found here.
A very old and antique heritage has been preserved in Rohtak. Baba Mast Nath Math, Gokaran, kiloi temple, and several more such fine looking buildings erected in traditional Indian and Mughal styles such as spacious havelis with ornate facade, finely carved wooden door sets and sand stone pillars, mosques that were once lavishly decorated in stucco work, dharamshalas with fine looking statues of Radha and Krishna and temple spires and are few of them. The survey was extended to study a few large village estates such as Balambha, Farmana Khas, Lakhan Majra, jassia, Bhaini Surjan and Meham by Society for Peoples’ Advancement, Technology and Heritage (SOPATH). The present Monastery was founded by Baba Mast Nath in 1731.Medieval Times
A centuries-old fort was situated at Rohtak, in present Quila Mohlla. That fort was built by shekhs of Yaman under Kazi Sultan Muhammad Surkh during Ghori Dynasty kings. The then emperor Delhi Mahmud Tughlaq posted two brothers named Malik Idrees and Mubariz Khan at that fort in 1400. The fort of Rohtak was besieged by Sayad Khizer Khan in 1410 which could only succeed after a long seize of six months.British period (1800-1947)

There are some tombstones, having dated inscriptions in the graveyard near mini secretariat building of Rohtak. Previously it was said to be surrounded by a garden, but now only a narrow strip of land is left for this cemetery.

The development of Rohtak caused controversy in 2013 as a result of the allegedly disproportionate number of state development projects that have been awarded to the city by Chief Minister Bhupinder Singh Hooda, who was born in a nearby village. This has led to severe criticism by both the opposition parties and some members of the governing Indian National Congress party, who have attacked Hooda for bias. Rao Inderjit Singh, a BJP leader from South Haryana, used Right to Information requests to determine that from a total of 5,135 announcements of schemes in the state, 2,045 went to the three districts of Rohtak, Jhajjar and Sonepat. These areas were in Hooda’s own constituency and that of his son, the Lok Sabha MP Deepender Singh Hooda. Of the 3,356 completed schemes, 1,560 were from these three districts whereas 1,796 schemes were completed in the rest of the state. Ambala MP Selja Kumari is also against the region-specific and biased development of Rohtak.
