Chengalpattu

Chengalpattu, also spelt Chengalpet or Chingleput, is a city in the northern part of the Indian state of Tamil Nadu. It serves as the administrative headquarters of Chengalpattu district, which was carved out of Kanchipuram district in 2019. The city lies on the Palar river basin and is an important node on the Chennai–Tiruchirappalli highway and railway corridor, situated about 55 kilometres south-west of Chennai.

Etymology

The name Chengalpattu is generally derived from the Tamil words referring to the red lily (chengazhuneer) that grew abundantly in the local tanks, combined with pattu (settlement). The colonial-era spelling Chingleput remained in official use until the late 20th century.

History

The region around Chengalpattu lay within the historical territory of Tondaimandalam and was successively under the Pallavas, the Cholas, and the Vijayanagara empire. During the Vijayanagara period a hill fort was constructed in the area, and the town later passed to the Nayaks of Arcot. In the 18th century Chengalpattu became a contested point during the Carnatic Wars between the British East India Company and the French, with the fort changing hands several times before coming firmly under British control.

Under the British, Chingleput was constituted as a district headquarters in the Madras Presidency, and the Chingleput district remained an administrative unit until it was renamed and reorganised in independent India. In 1997, parts of the old Chingleput district were used to form Kanchipuram district. On 29 November 2019, the Government of Tamil Nadu bifurcated Kanchipuram district to create the new Chengalpattu district, with Chengalpattu town as its headquarters.
