The OBCs have contributed immensely to the rise of BJP on political horizon in India. The most pertinent example was UP in 1990s when the BJP used to sweep elections in the state. It happened because BJP introduced a winning social engineering formula in the state. The leadership was handed over to Kalyan Singh, a powerful OBC leader, while the forward castes were brought under one umbrella on Hindutva plank . This combination of an OBC leader and robust support of forward castes proved to be a lethal combination and propelled BJP into power with a clear cut majority.
