A state of emergency, proclaimed in 1957 to deal with this regional threat and with the confiscation of Dutch assets under nationalist and communist pressure, legalized and extended the power of the military in every region. ABRI moved quickly to take over Dutch plantations and businesses, and to prevent the PKI doing so through its militant unions. These assets ensured that the military would be able to sustain itself independent of the civilian government, and that the officer corps had a major interest in the continuation of emergency conditions that justified this privileged position. When the dissident colonels allied wjth some Masjumi and socialist politicians to proclaim an alternative “Revolutionary Government of Indonesia” (PRRI) in 1958, Sukarno and Nasution moved decisively to use Java troops to crush the rebel units in Sumatra and North Sulawesi. Although elite officers and politicians were treated mildly, dismissed or exiled rather than executed, some 35,000 men died on both sides of the battlefield. The Army extended its role in political and economic matters, particularly in the ex-rebel provinces of Sumatra and Sulawesi occupied by Javanese units. It became more centralized, more ready to use violence domestically, and more Javanese (about 80% of the top officer corps by 1970), as officers from Sumatra and Sulawesi were dismissed or marginalized.
