Ambur

Historically, Ambur has remained a major town in the North Arcot district of the Madras Presidency (present-day Tamil Nadu). In 1989, the North Arcot district was bifurcated into Vellore and Tiruvannamalai districts, and Ambur remained part of the Vaniyambadi Taluk in the Vellore district. In 2009, Ambur taluk was formed by splitting major land areas from the neighbouring Vaniyambadi taluk and few parts from the Vellore taluk. Later in 2019, the Vellore district was further trifurcated into Ranipet, Tirupathur, and Vellore districts, with Ambur becoming part of Tirupathur district.

Ambur is located on the banks of the Palar River between Chennai and Bangalore. Ambur has a sizeable leather industry, and is known for its spicy biryani and for the sweet, makkhenpeda. Ambur was the site of two major military actions in the 18th century.
