Master Gurbanta Singh
Master Gurbanta Singh (4 August 1904 – 5 February 1980) was an Indian politician, educationist and social reformer from Punjab, India. He was a former member of the Unionist Party and then Indian National Congress. Master Gurbanta Singh was one of the tallest Dalit leaders of Punjab. Early life 
Master Gurbanta Singh was born in Dhaliwal village, Jullundur, Punjab, in British India. He completed his education at Jalandhar and became a school teacher at Sain Dass A.S Senior Secondary School (Jalandhar). His political career started when he became village sarpanch. After the influence of the Ad Dharm movement, he declared himself Ad Dharmi in the 1931 census along with other Dalits of Punjab, especially in Doaba. Ad-Dharm Movement 
In the mid-1920s, Gurbanta Singh came into contact with Mangu Ram Mugowalia, a fellow caste man and also a founder member of the Ghadar Party. Mangu Ram had started the Ad-Dharm movement and established many mandals in the Doaba region of Punjab, where Dalits formed a major share of the population. Although in the initial years, Singh's closeness to the movement was because of oppression and illiteracy among Dalits of Punjab, later, he fully got involved in this social movement and became General Secretary of Ad-Dharm Mandal of Jalandhar. Both Mangu Ram and Gurbanta Singh took the Ad-Dharm movement to its zenith, and it became the most successful Dalit reform movement in North India. At the same time, he joined Unionist Party and fought the election unsuccessfully. After years of long contributions to the movement but due to differences with Seth Kishan Dass, another prominent leader of the Ad-Dharm movement, he left the Mandal and became active in politics. Politics 
Master Gurbanta Singh again fought elections from Jullundur (Reserved Seat) and became successful. He was made Parliamentary Secretary in the Ministry of Malik Khizar Hayat Tiwana (Premier of Punjab). In 1947, India gained independence, and he joined Indian National Congress. He fought elections in 1952 and 1957 also but lost elections. In 1962, he won from the Kartarpur constituency and was chosen as a Minister in the Cabinet of Chief Minister Pratap Singh Kairon from 1956 to 1964. He became Agriculture Minister of Punjab and played an instrumental role in establishing Punjab Agricultural University (Ludhiana), which paved the way for the Green Revolution in India and was a key player in the construction of the Bhakra Dam. In the 1972 Punjab Assembly Elections, Gurbanta Singh was elected unopposed and joined the Ministry of Giani Zail Singh (former Chief Minister of Punjab). He became a Member of the Punjab Legislative Assembly six times and slowly became known as the biggest Dalit leader of Punjab. In those times, even the Republican Party of India, founded by Dr B R Ambedkar himself became small in front of his stature. Gurbanta's political clan 
Master Gurbanta's family is known to be one of Punjab's most prominent political families.
