There is a bewildering contrast between the superficial calm of the 1930s in Indonesia and the turbulence of the immediate post-war period. In addition to the enormous upsurge of anti-colonial militance, the years following the Japanese surrender were marked by an unprecedented degree of conflict amongst Indonesians, as society adjusted to the radically changed conditions of independence. In other countries occupied by Japan, notably Burma and Malaya, ethnic animosities were also unusually overt after the war. It seemed natural to ask, as Elsbree did in his pioneering essay of 1953:
did the [Japanese] occupation, with its dissolution of existing ties, aggravate the fissures of the old order? … Did the Japanese deliberately pursue a “divide and rule” tactic, and is their policy to be held responsible for the violent outbursts and the general increase in racial tension since the end of the war?
