Avadi

The exact origin of the name 'Avadi' is not known. One version has it that it is the combination of "Aa" (meaning cow) and "Adi or gudi (kudi)" (meaning place in Tamil), indicating that the place had many cows. One of the more popular theories about the origin of the name is that it is an acronym for "Armoured Vehicles and Ammunition Depot of India". However, this is most likely a backronym invented more recently. The entity "Armoured Vehicles and Ammunition Depot of India" does not appear in any British records. This acronym is further disputed by the existence of a railway station going by the name of "Avadi" in the locality since 1873 before the establishment of defence industries. Several British documents from the 19th century refer to the place as "Avady", which doesn't match the widely circulated acronym theory. The name Avadi (Avady) was already in use by 1856, when the first public railway was opened in the Madras Presidency. This predates the transfer of the Madras Presidency's arsenal from Fort St. George, India in the city of Madras, to Avadi, which was done sometime after 1870, which contradicts the popular acronym theory. ==History==

The suburb is part of the "auto belt" that developed when the automobile industry developed in Madras, primarily in the city's industrial north and west regions, in the early post-World War II years. The famous session of the Indian National Congress was held at Avadi on 10 January 1955 where the Avadi Resolution was declared that the objective of the Congress was the establishment of a "socialistic pattern of society" in India. This historical meet emphasised the importance of socialism and its impact on social development. Jawaharlal Nehru with Morarji Desai and other Congress leaders at the AICC session declared that a socialistic pattern of society was the goal of the Congress. ==Geography==
