Karpuri Thakur was a legendary political leader and social reformer from Bihar, best known for his unwavering commitment to the upliftment of backward and marginalized communities. Born on January 24, 1924, in Pitaunjhia village, Samastipur district, Bihar, he belonged to a poor Nai (barber) family and rose to prominence through honesty, simplicity, and grassroots activism. He actively participated in the Quit India Movement in 1942 and was imprisoned for his role in the freedom struggle. Thakur served as the Chief Minister of Bihar twice (1970–71 and 1977–79). His most historic and controversial decision came in 1978 when he implemented the Mandal Commission recommendations at the state level, providing reservation in government jobs for backward classes—well before the national government did. This bold move earned him immense support among the backward castes but also triggered significant opposition from the upper castes. Known as “Jan Nayak” (People’s Leader), Karpuri Thakur led a life of extreme simplicity—he never owned a house and avoided luxuries while in office. Karpuri Thakur’s politics laid the foundation for the social justice movement in Bihar, which influenced generations of leaders, including Lalu Prasad Yadav and Nitish Kumar. He is remembered as a true icon of equity, inclusiveness, and grassroots leadership, and his legacy continues to inspire movements for social justice across India.
