 The 1938 riots spurred the PNP to unionise labour, although it would be several years before the PNP formed major labour unions.The party concentrated its earliest efforts on establishing a network both in urban areas and in banana-growing rural parishes, later working on building support among small farmers and in areas of bauxite mining.The PNP adopted a socialist ideology in 1940 and later joined the Socialist International, allying itself formally with the social democratic parties of Western Europe.
