Until the turn of the 19th century, the villages to the west of Mount Road formed a part of Chingleput District. The Long Tank, which formed the western frontier of the city, was drained out in 1923. That very same year, the administration of the Mambalam zamindari, situated to the west of the Long Tank, was relinquished by its hereditary chief. The region had several paddy fields. During 1923–25, the township of "Thiyagaraya Nagar" named after Sir P.T. Thyagaraya Chetty was carved out of the southern part of the erstwhile Mambalam zamindari. A park was developed at the centre of this new locality and was named in honour of the then Chief Minister, as Panagal Park. Soon afterwards, Pondy Bazaar began to make its appearance. According to historian S. Muthiah, it was initially known as 'Soundarapandia Bazaar' after Justice Party politician W. P. A. Soundarapandian Nadar. A well-planned residential area was created. Most of the streets in the new locality were named after provincial cabinet ministers, Justice Party bosses or officials in the administration.
