Senapati Bapat was born in a MarathiChitpawan family on 12 November 1880 in Parner. His family was originally from Ratnagiri. He was educated at Deccan College and then travelled to Britain on a government scholarship in order to study engineering.
As a revolutionary
During his stay in Britain, he was associated with India House, spending a majority of his time learning bomb-making skills instead of pursuing his official studies. He became associated at this time with the Savarkar brothers, Vinayak and Ganesh. Bapat, who had considered blowing up the Houses of Parliament in London, took his skills back to India and passed them on to others. While in hiding after the Alipore bombing of 1908, Bapat travelled the country and discovered that the majority of the Indian population did not realize that their country was under foreign rule. At this point, his focus shifted from overthrowing the British government to educating the population. In 1912, he was arrested in connection with the bombing and was sentenced to be imprisoned. He was free by 1915, and was a "seasoned revolutionary", according to Richard Cashman. He had joined the staff of Mahratta and was one of several influential figures from the Poona area who were aligned with Bal Gangadhar Tilak's attempts to establish local organisations supporting the cause of Indian independence.
He re-aligned himself with Gandhi's vision of swaraj. In late 1920, following the death of Tilak and despite having been a fervent supporter of the Tilak's vision. This was a considerable shift, given his firebrand nature and willingness to use violence, but although he took the Gandhian oath of non-violence he remained willing to use force when he thought it necessary. From 1921, Bapat led the three-year farmers' protest against the construction of the Mulshi Dam by the Tata company. Ghanshyam Shah considers this to be "the first recorded organised struggled against displacement" caused by an irrigation project. The company had initially dug test trenches on land without obtaining permission and the farmers, who were mostly tenants, objected in fear of losing their lands. The dam was eventually constructed and thus the protest ultimately failed. Compensation for lands submersed by the dam's construction was eventually arranged but was given to the landlords rather than to the tenants. Although satyagrahas are intended to be non-violent, Bapat was jailed for vandalism of the construction project: rather than be captured for this, he turned himself in. His third jail sentence was for speaking at a public gathering held by Subhas Chandra Bose.
