Broadly speaking, the intellectual basis for what was to become developed both from external impetus from the spread of Indonesian nationalist ideas into Malaysia, and the development of an anti- colonialist intellectual climate within the Sultan Idris Training College for Malay Teachers. In 1927, Malay nationalism in British Malaya received intellectual impetus from their Indonesian cousins in the wake of the failed 1926 Communist uprising against the Dutch in the Dutch East Indies. Indonesian nationalist leaders, such as the Comintern agent Tan Malaka, sought refuge in Malaya in the wake of the crackdown that ensued, where they spread their radical anti-colonial ideology to Malaya.
