The party was established on 1 May 1985 by Dr. George Belle, who served as the general secretary of the party.^[1]The party had a pro-Soviet orientation and grew out of MONALI, an earlier Marxist movement based at the Cave Hill University of the West Indies campus which had gained national notoriety during the 1983 Grenada invasion.^[2][3][4][1] When announcing the transformation of MONALI into the Workers Party of Barbados, Belle affirmed the party would be organized along the lines of democratic centralism and would work on a basis of a programme of "progressive reforms and revolutionary democratic demands".^[5] The founders of the party included trade unionist Ricky Parry.^[4]
