The Poona Sarvajanik Sabha (Poona Public Society) was founded on 2 April 1870 as a socio-political organization at Poona (Pune) in present-day Maharashtra. The Poona Sarvajanik Sabha was established on 2 April 1870 at Poona originally because of the discontent of the people over the running of a local temple. The Deccan Association formed in 1850 and the Poona Association formed in 1867 had become defunct within a few years and the western educated residents of Poona felt the need for a modern socio-political organisation.
