For almost six decades the movement to separate
Jharkhand from
Bihar had been attempting to gain a foothold. The
Jharkhand Party gained political strength but commissions examining the demands for a separate Jharkhand State consistently rejected its demands. Before 1962, the Jharkhand Party held between 23 and 32 seats in the
Bihar Legislative Assembly. In 1962, it won 20 seats.
Jaipal Singh Munda merged the Jharkhand Party with the
Indian National Congress in 1963 and became a minister in Vinodanand Jha's government in Bihar. But other members did not join the Congress. In the
1967 general election, the party had a very poor showing with only eight Assembly seats. The party soon split into several splinter parties each claiming to be the real Jharkhand Party. These included the Jharkhand Party led by
N. E. Horo, the Jharkhand Party led by Naren, and the
All India Jharkhand Party led by Bagun Sumroi. There was also the
Hul Jharkhand Party led by Justin Richard, which further fragmented and became the Bihar Progressive Hul Jharkhand Party led by
Shibu Soren. Jharkhand Mukti Morcha was founded by Soren,
Binod Bihari Mahato and
Marxist Co-ordination Committee leader
A. K. Roy. The party was officially created on the birthday of
Birsa Munda, a 19th-century tribal warrior from Jharkhand, who fought against British rule in the region. On 4 February 1973, Mahato became president of the party and Soren became its general secretary. Prominent party leaders at that time included Roy,
Nirmal Mahto and
Tek Lal Mahto, among others. == Early years ==
