As the Bihar Movement, spearheaded by students, exploded onto the national scene, Yadav was elected president of Patna City Bihar Chhatra Sangharsh Samiti. The famed Gandhian Jai Prakash Narayan had started his socio-political movement. 1974 was a year of discontent that ushered in high inflation, unemployment and lack of supplies of essential commodities. On 8 April 1974, the students of Bihar Chhatra Sangharsh Samiti led a massive silent procession. Yadav participated in this movement under the tutelage of Lok Nayak Jay Prakash Narayan. This association with JP landed him in jail for 23 weeks during 1974–1976. On call of Lok Nayan JP, NYadav left his studies in the final year and dedicated himself to the socio-political revolution that is now famously called The Bihar Movement.
