Garhmukteshwar is an ancient settlement that is mentioned in the Bhagavata Purana and the Mahabharata. There are claims that it was a part of ancient Hastinapur, the capital of the Pandavas. An ancient fort, repaired by the Maratha leader Mir Bhawan, became, under the British, the headquarters of the tehsil. The name of the town is derived from the temple of Mukteshwar Mahadeva, dedicated to the goddess Ganga who is worshipped there in four temples. The town has 80 sati pillars, marking the spots where Hindu widows are said to have become Sati-Mata. The town also has a mosque, built by Gays-ud-din Balban, that bears an inscription in Arabic dating to 682 Hijri (1283 A.D.).

Garhmukteshwar was the scene of major anti-Hindu violence in November 1946, at a time when various areas of British India were experiencing significant communal unrest as the partition of the country into India and Pakistan loomed. Gyanendra Pandey describes the place as "a metaphor for the atrocities of Partition; and Partition itself a metaphor for the kind of extraordinary genocidal violence that was not witnessed again in India, perhaps until 1984". Official investigations into violence in Uttar Pradesh at that time note that there was a "desire for revenge" among both Hindus and Muslims, resulting from news of similar violence in Calcutta.
