The Bihar Movement in 1974 was indeed led by Jayaprakash Narayan. Jayaprakash Narayan, also known as JP, was a prominent Indian independence activist and political leader. He played a significant role in the Bihar Movement, which was a massive popular uprising against corruption and misgovernance in the state of Bihar, India.

JP, who had already gained immense popularity as a social and political reformer, emerged as the leader of the movement and spearheaded the protests.

Here is a detailed explanation of the Bihar Movement in 1974 and JP's role in it:

Background:

- He believed that the existing political system had become corrupt and needed a complete overhaul.
- JP's call for Total Revolution inspired millions of people, especially the youth, who were disenchanted with the state of affairs in Bihar.

Formation of Bihar Sangharsh Samiti:
- In 1974, Jayaprakash Narayan formed the Bihar Sangharsh Samiti (Bihar Struggle Committee) as a platform to unite various opposition groups, activists, and organizations against the state government.
- The Samiti became the driving force behind the Bihar Movement and organized mass protests, marches, and demonstrations across the state.
