 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.This was a significant development in Malay nationalism, given that the nationalism that had developed in Malaya, in contrast to the movements developing in the other British colonial possessions of India and Burma, remained relatively placid and moderate.Groups such as the Kesatuan Melayu Singapura, while advocating self- strengthening within the Malayan community, for instance by purchasing land for Malay reservations in 1928, or by pooling funds to send Malays to Oxford and Cambridge in order to ensure the continued preeminence of Malays in the administration of British Malaya, did not challenge British rule, and opted to collaborate with the British.
