Karpoori Thakur, often called Jannayak, was a legendary leader from Bihar who had a significant impact on India’s politics. In early 2024, he was posthumously honoured with the Bharat Ratna in recognition of his extraordinary contributions to society. Commemorating his birth centenary, this gripping biography brings to light the life, legacy and enduring relevance of Thakur. It focuses on Karpoori Thakur’s politics, which introduced ‘quota within quota’ and opens a window to his role in bifurcating reservation among the backward classes and women in 1978.
