In election after election since 2014, both at the Union and state levels, the BJP has won more often than it has lost―a clear indication of growth beyond its core Hindu base. The question is, why do so many people across divisions of caste, religion and gender vote for a party with unapologetically aggressive Hindutva politics? Are its much—publicised development schemes, whatever their flaws, the big pull factor? Or the active mobilisation of the RSS cadre to its cause? In this fascinating revisionist history, political scientist and journalist Nalin Mehta examines how the BJP became the world’s largest political party. He goes beyond the usual narrative of the party’s Hindutva politics to explain how, under Narendra Modi, it reshaped the Indian polity using its own brand of social engineering.
