This group originated with Antonio Soberanis Gómez and the Labourers and Unemployed Association (LUA) between 1934 and 1937 and continued through the General Workers Union (GWU).
Its leaders came from the LUA and the local branch of Marcus Garvey's Universal Negro Improvement Association (UNIA).
The greatest achievements of the agitation of the 1930s, and the ensuing Report of West India Royal Commission, were the labour reforms passed between 1941 and 1943.
The Employers and Workers Bill, passed on 27 April 1943, finally removed breach-of-labour-contract from the criminal code and enabled British Honduras's infant trade unions to pursue the struggle for improving labour conditions.
A branch of Marcus Garvey's Universal Negro Improvement Association (UNIA) movement formed in British Honduras in 1920.
Garvey himself came to British Honduras to visit the new branch in 1921, and spoke at public meetings about the aims and activities of the UNIA.
He joined trained lawyers Said Musa and Assad Shoman in the formation of their People's Action Committee (PAC), which was against "the North Atlantic economic domination (of Belize)" (Shoman) and in the analogue movement RAM (Revolutionary Action Movement) formed by a fusion of the two.
The goals of the CSAG included a "Natives First" campaign and an extension of the franchise to elect a more representative government.
One member of this group, George Cadle Price, topped the polls in the 1947 election when he opposed immigration schemes and import controls and rode a wave of feeling against a British proposal for a federation of its colonies in the Caribbean.
The leaders educated people about the problems of colonialism and how the poor living conditions were caused by the system of exploitation.
George Price was named head of the GWU in April 1952, and returning leaders Richardson and Goldson called for a "Crusade against Colonialism".
did not agree to negotiate with the union for wage improvements and better working conditions and shut down its sawmill leaving 268 workers jobless.
This was met with violence from demonstrators and a number of people were arrested, but by December 8 some 48 workers were on the job and the GWU called off the strike.
Despite the non-compliance of the B.E.C., the leaders felt that the strike was a success because it showed that working class solidarity gave workers power and with that they gained benefits.
The "loyalists" were those people in the "middle class", such as traders and civil servants, that benefited from the colonial system and argued against adult suffrage.
Instead of universal suffrage, they suggested a literacy test for voters; a system of indirect voting by the districts outside of Belize City; and reserved powers for the governor.
For example, a crowd stoned the homes of some politicians regarded as Pro-Britishers and harmed the police guard at the Governor's residence.
The poor economic and social conditions of many people living in Belize in the 1950s encouraged them to think about self-government and independence, thus strengthening the nationalist movement.
