As a young student leader and a dedicated swayamsevak, Yadav worked tirelessly for the cause of student causes. His work and popularity saw him rise rapidly through the ranks of students politics. On 18 February 1974, the Patna University Students Union organized a convention which invited student leaders from the whole state. They formed Bihar Chhatra Sangharsh Samiti (BCSS) to spearhead the agitation. This movement saw the rise of many contemporary Bihar leaders. Notable among them were Nand Kishore Yadav, Lalu Prasad Yadav, Sushil Kumar Modi and Ram Vilas Paswan.
