History of the Anushilan Samiti
Around 1902, Aurobindo Ghosh arranged for Bannerjee to return to Calcutta to begin organisational work, where he began a gymnasium and a youth society. It was at this time that Bannerjee came in touch with Vibhuti Bhushan Bhattacharya, Sarala Devi Ghoshal and Pramathanath Mitra. In Calcutta, a few clubs and societies were still active at the time. Most notable was a gymnasium in Ballygunge Circular Road run by Sarala Devi herself, a second was an organisation named "Anushilan Samiti" founded by Satish Chandra Basu with the patronage of Pramathanath Mitra. A third one was a youth club called "Attōnnōti Samiti" (Self-improvement society) in central Calcutta.
Ponnambalam Arunachalam
Arunachalam's became interested in politics during his university days. He agitated for political reform whilst still working in the civil service. In retirement Arunachalam became involved in politics, founding the Ceylon National Association and the Ceylon Reform League, of which he was chairman, in 1917. He was one of the founders of the Ceylon National Congress (CNC) in 1919 and served as its first president from 1919 to 1920. Arunachalam left the CNC in 1921 following disputes about communal representation in the Legislative Council, which Arunachalam opposed, and the connivance of Sinhalese politicians which resulted in no Tamils being elected from Western Province at the 1921 legislative council election. He founded the Ceylon Tamil League in 1923.
