Dr. Karmaveer Bhaurao Patil was born on 22 September, 1887 at Kumbhoj, in the district of Maharashtra. His native place is Aitawade Budruk., Dist. Sangli. He came from the tenacious Jain family but rejected its rigorous religious rites and fought all his life against the social ills that impede the secularist growth of society. During his school days, he came under the direct influence of the then king of , Rajarshi Chh. Shahu Maharaj who was a staunch advocate of social equality and great promoter of education for the backward communities of . Another great social reformer from whom, he drew inspiration was Mahatma Jyotirao Phule. While working at Ogales, Kirloskars and Coopers, Bhaurao would save his time to devote himself to the activities of Satya-Shodhak Samaj.He would perform Satya Shodhaki Jalasas in the villages of Maharashtra and awaken the people to the dire consequences of the social evils of the time.He realised that the social ills could be remedied through the education of the masses alone and so laid the foundation of the Rayat Shikshan Sanstha by opening a Boarding House at Kale (Tal-Karad, Dist-Satara) in 1919. Soon, however, in 1924 he shifted the head-quarters of his educational institution to Satara.
It is a significant coincidence that Mahatma Gandhi’s Freedom Movement and Bhaurao Patil’s Mass-Education Movement started functioning at about the same time in the year 1920. Bhaurao first saw Gandhiji at a public meeting in , in 1921. He was stunned to see Gandhiji only in a loin-cloth at the huge rally. So deeply was he impressed that he resolved to wear khadi for the rest of his life. Mahatma Gandhi was struggling hard to attain the political freedom for the country. Karmaveer Bhaurao was rebellious by temperament but revered freedom. Bhaurao was uncertain as to whether political freedom or social reforms should receive prime concern, till the Kameri Satyagraha of 1930, but thereafter he devoted himself fully to the cause of mass education. In his view, education is the means to empower the masses to enjoy the fruits of freedom and to emancipate them from social, economic and cultural slavery.
Karmaveer Bhaurao Patil (22 September 1887 – 9 May 1959), born in Kumbhoj, Kolhapur, was a social activist and educator in Maharashtra, India. A strong advocate of mass education, he founded the Rayat Education Society. Bhaurao played an important role in educating backward castes and low income people by coining the philosophy earn and learn. He was a prominent member of Satyashodhak Samaj (Truth seeker's society), founded by Mahatma Jotirao Phule. The people of Maharashtra honoured him with the sobriquetKarmaveer (King of actions) and the Government of India awarded him with Padma Bhushan in 1959 in India.
Karmaveer Bhaurao Patil was born in a Jain farmer family at Kumbhoj in Kolhapurdistrict. Bhaurao's father was a clerk in the revenue department for East India company. Bhaurao was one of the first few Jains known to have passed 8th class of secondary school. During childhood, Bhaurao was heavily influenced by Chhatrapati Shahu Maharaj, the honorable Maharaj (King) of Kolhapur, who provided a facility to Karmaveer Bhaurao Patil to stay in the palace of Kolhapur with Maharaj and study. The King of Kolhapur was promoter of social equality and education of people belonging to backward castes. Eventually, his father sent him to Kolhapur for further education, where he got in contact with Satya Shodhak Movement and found other sources of inspiration, Mahatma Phule and Maharshi Vitthal Ramji Shinde. Bhaurao garnered political interest and decided to express his role in the fight for Indian freedom struggle by working in other beneficial fields like public education. While he worked for Ogles, Kirloskars and Coopers he participated in activities of Satya Shodhak Samaj. He had realized by then that the only remedy for the social evils of those times was the education of the masses. In 1919, he started a hostel where children from lower castes and poor families could stay and get an education, while working to pay the expenses. This was the foundation of what later became Rayat Shikshan Sansthan.
As Bhaurao started working on his program to educate the masses, Gandhiji had also launched his campaign to free India (independence movement). During a public meeting in 1921, Bhaurao happened to come across Gandhiji at Mumbai. He was highly impressed by Gandhi's appearance in a loin cloth and his philosophy of Khadi. Following this encounter, Bhaurao decided to adopt Khadi attire and follow Gandhian principles in everyday living. Eventually he vowed to see it to completion, establishing 101 schools in Gandhi's name. However, Gandhiji and Bhaurao had a difference of opinion on the subject of accepting grants from government for educational activities in post-independence India. Gandhiji believed that even if the government wanted to give grants in aid to an educational institute (or institutes) without putting any restrictions on the institute(s), this would eventually devolve into edicts and oversight. No one can expect to receive money without conditions forever. Bhaurao saw no such problem with accepting grants from the government.The bountiful banyan is the biography of Karmaveer Bhaurao Patil written by Barrister P. G. Patil.

Rayat Education Society
While employed in the Kirloskar factory at Kolhapur, Bhaurao began working for the Satyashodhak Samaj. In a meeting of Satyashodhak Samaj, held at Kale near Karad, a resolution passed that in order to run the Satyashodhak movement successfully it would be necessary to educate the Bahujan Samaj. Accordingly, Bhaurao Patil established Rayat Shikshan Sanstha at a small village named Kale, on 4 October 1919. This society focused on the children of the masses, so it was named Rayat, the Marathi word for "masses". During Bhaurao's lifetime the Sanstha created thirty-eight cosmopolitan boarding schools, 578 voluntary schools, six training colleges, 108 secondary schools and three colleges.
