Luv-Kush equation
The Luv-Kush equation is a political term used in the context of the politics of Bihar, to denote the alliance of the agricultural Kurmi and the Koeri caste, which was assumed to be approximately 15% of the state's population (7% approximately in the Bihar caste-based survey 2022) The alliance of these two caste groups has remained the support base of Nitish Kumar, as against the MY equation of Lalu Prasad Yadav, which constitutes Muslims and the Yadavs. Caste consciousness and the quest for political representation largely drive the politics of Bihar.
