He joined the Indian National Congress in 1886 and left it after the split in the Congress at the Surat session in 1907. He rejoined the Indian National Congress in 1916 at the Lucknow session and left it again in 1921. Thrice he visited England, in 1896, 1908 and 1919. The most important event in Bipin Chandra Pal's life was his refusal to give evidence against Arbindo Gosh in a sedition case against him in 1907 for which he suffered rigorous imprisonment for six months. But this made him a national hero.
On August 12, 1901, Bipin Chandra Pal started an English Weekly called "New India". In its inaugural issue, as founder-editor, Pal declared its ideals in stirring tones: "Its stand point is intensely national in spirit, breathing the deepest veneration for the spiritual, moral and intellectual achievements of Indian civilization and distinctly universal in aspiration". "New India" focused primarily on the economic and educational reconstruction of India with special emphasis on cultural regeneration rather than lopsided political agitation alone.
When the British Government announced their plan of partition of Bengal in December 1903, it was Bipin Chandra Pal who constructed the revolutionary political philosophy of Young Bengal and succeeded in annexing Madras or South India to that revolutionary creed. It is not therefore surprising that early Tamil Revolutionary Nationalists like Maha Kavi Bharathi, Va. Ve. Su. Iyer, Subramaniya Siva, and Va. Vu. Chidambaram Pillai and many others came under the revolutionary spell of Bipin Chandra Pal in the first decade of 20th century.
