The Jharkhand Mukti Morcha (JMM) was formed in 1973 with the primary objective of spearheading a movement to establish a separate state of Jharkhand out of the southern region of Bihar.1

The party played an instrumental role in this decades-long campaign by uniting indigenous Adivasi tribal communities, peasants, and industrial workers. By advocating for the protection of tribal identity, resources, and inclusive growth, the JMM provided a political voice to marginalized groups in the resource-rich region.1

Through persistent advocacy and political mobilization, the JMM's efforts culminated in the successful creation of Jharkhand state on November 15, 2000—a date chosen to coincide with the birth anniversary of the tribal leader Birsa Munda. Since the state's formation, the JMM has remained a central political force, continuing its mission to promote the welfare of the region's tribal populations.1
