All Jharkhand Students Indian Union, is a state political party of Jharkhand state, India. AJSU was founded June 22, 1986, modelled after All Assam Students Union. The founders of AJSU were disillusioned with the previous Jharkhandi political parties, and wanted more militant agitations.Mostly activated in Santhal Pargana (Dumka, Deoghar, Godda).
AJSU organized general strikes and a campaign to boycott the Lok Sabha elections in 1989. By 1990 however, AJSU had taken a more pragmatic line and had candidates for the Bihar state assembly election on the Jharkhand Mukti Morcha symbol. Today, AJSU contests elections under its own name.
