He believed and advocated the use of arms to free India from the British and created a network of Indians in England, equipped with weapons.

In 1908, brought out an authentic informative researched work on The Great Indian Revolt, which the British termed as "Sepoy Mutiny" of 1857. The book was called "The Indian War of Independence 1857". The British government immediately enforced a ban on the publication in both Britain and India. Later, it was published by Madame Bhikaiji Cama in Holland, and was smuggled into India to reach revolutionaries working across the country against British rule.

In 1909, Madanlal Dhingra, a keen follower of Savarkar shot Sir Wyllie after a failed assassination attempt on the then Viceroy, Lord Curzon. Savarkar conspicuously did not condemn the act. When the then British Collector of Nasik, A.M.T. Jackson was shot by a youth, Veer Savarkar finally fell under the net of the British authorities. He was implicated in the murder citing his connections with India House. Savarkar was arrested in London on March 13, 1910 and sent to India.

After a formal trial, Savarkar was charged with serious offences of illegal transportation of weapons, provocative speeches and sedition and was sentenced to 50 years' of jail and deported to the Kalapani (Blackwaters) at Andaman cellular jail.

In 1920, many prominent freedom fighters including Vithalbhai Patel, Mahatma Gandhi and Bal Gangadhar Tilak demanded the release of Savarkar. On May 2, 1921, Savarkar was moved to Ratnagiri jail, and from there to the Yeravada jail. In Ratnagiri jail Savarkar wrote the book 'Hindutva'. On January 6, 1924 he was h freed under the condition that he would not leave Ratnagiri district and abstain from political activity for the next five years. On his release, Veer Savarkar founded the Ratnagiri Hindu Sabha on January 23, 1924 that aimed to preserve India's ancient culture and work for social welfare.

Later Savarkar joined Tilak's Swaraj Party and founded the Hindu Mahasabha as a separate political party. He was elected President of the Mahasabha and toiled for building Hindu Nationalism and later joined the Quit India movement.

The Hindu Mahasabha opposed creation of Pakistan, and took exception to Gandhi's continued Muslim appeasement stances. Nathuram Godse, a volunteer of the Hindu Mahasabha, assassinated Gandhi in 1948 and upheld his actions till his hanging. Veer Savarkar was arrested and indicted by the Government of India in the Mahatma Gandhi assassination case. But he was acquitted by the Supreme Court of India, for reasons of lack of evidence.

Veer Savarkar died on February 26, 1966 at the age of 83.
