however, there were also moves towards unity between the competing factions. during the 1980s, there was cooperation between the mkss and cpi(ml) liberation in the struggle against bhoomi sena and state repression. the two parties jointly founded daman virodhi sanyukt morcha ('united anti-repression front'). after the arwal massacre of 1986, the two groups organised a historic "gherao" outside the bihar legislative assembly. cpi(ml) liberation broke all links to cpi(ml) party unity in 1988, after two massacres committed by cpi(ml) party unity in jehanabad district in which 30 cpi(ml) liberation followers were killed. in 1993 the all india people's resistance forum (aiprf) was founded, a legal organization. aiprf was co-sponsored by cpi(ml) party unity, mcc and the communist party of india (marxist-leninist) people's war, and functioned as a centre of coordination of activities amongst middle-class constituencies for the three groups.
