The name "Sandi" is said to be derived from the name Santan Dih or Santan Khera, which it received after Raja Santan Singh, a Sombansi king said to have ruled here until 1398, when he was defeated by Muslim conquerors and fled to Kumaon. His fort, whose ruins still exist to the south of the modern town, had a deep moat, and the besieging Muslim army had little success until they dug a channel from the moat to the Garra. The Muslims at first built a town southeast of Santan Khera, called Fatehpur Islamabad, but 22 years later it was abandoned due to disease and the site of Santan Khera was reoccupied. It was officially renamed Ashrafabad, but the name never caught on and instead it was called Santan Dih or Sandi. Around the turn of the 20th century, the main mahallas were Saiyidwara, Salamullahganj, Munshiganj, Khalisa, Auladganj, Nawabganj, and Uncha Tila. Uncha Tila was the site of an earthwork fortification built by Shuja-ud-Daula in the 1700s, a factory built by Europeans later on, and a chaukidar's fort. Uncha Tila was the site of the tehsil headquarters when Sandi was originally selected as a tehsil by the British, although it was later moved to Bilgram. Nawabganj was the site of the main bazaar in Sandi; smaller ones  were held at Khalisa, Auladganj, Munshiganj, and Salamullahganj.
