The Dutch authorities, after various changes to the administration of the eastern islands of the East Indies, established the Great East region in 1938. Four years later, the Japanese invaded, and this area was placed under the control of the Imperial Japanese Navy. Following the Japanese surrender and the Indonesian declaration of independence in August 1945, Indonesian republicans began fighting to secure Indonesian independence from Dutch colonial control. However, Dutch administrators backed by Australian troops arrived in the area previously controlled by the Japanese Navy, and prevented republicans from establishing an administration. From 16–25 July 1946, the Dutch organised a conference in the town of Malino on Celebes as part of their attempt to arrange a federal solution for Indonesia. The Malino Conference resulted in plans for a state in Borneo and another for East Indonesia, areas where the Dutch held both de facto and de jure control. Later that year, Republic of Indonesia agreed to the principle of a federal Indonesia with the Linggadjati Agreement of 15 November. The Denpasar Conference of 18–24 December was held to work out the specifics of a state to be called the State of the Great East.. That state was established on 24 December and, on 27 December, renamed the State of East Indonesia. With the realisation of the UnitedStates of Indonesia on 27 December 1949, East Indonesia became a constituent of the new federation. In much of Indonesia, the federal USI was seen as an illegitimate regime foisted on the islands by the Dutch, and many of the federal states began to merge with the Republic of Indonesia. However many in East Indonesia, with its non-Javanese population and greater number of Christians, opposed moves toward a unitary state. East Indonesia had already dealt with the "Twelfth Province" secessionist movement in Minahasa in 1948. The formation of East Indonesia's last cabinet in May 1950 with the intention of dissolving the state into the Republic of Indonesia led to open rebellion in the largely Christian Moluccas and the proclamation of an independent Republic of the South Moluccas. The USI was dissolved on 17 August 1950 and the rebellion in the Moluccas was crushed in November of the same year.
Government
The Denpasar Conference of 18–24 December 1946 approved the Regulations for the Formation of the State of East Indonesia which supplemented the 1927 Dutch colonial law and established the provisional governmental framework of the new state until a constitution could be approved. Although the draft constitution was passed by the legislative on 1 March 1949, it was never adopted and the 1946 regulations remained n place until the state was dissolved. The state was to have an executive president who would appoint a cabinet and a legislature. A number of powers were explicitly reserved for the future United States of Indonesia, of which East Indonesia would be a constituent member.
President
nese nobleman Tjokorda Gde Raka Soekawati was elected president at the Denpasar Conference that established the state, and held that position for the duration of the state's existence.
The State of East Indonesia was divided into five residencies which were in turn divided into districts ' and subdistricts ', an administrative structure inherited from the Dutch. Within the residencies were 13 autonomous regions. These regions, listed in Article 14 of the Regulations for the Formation of the State of East Indonesia ', were South Celebes, Minahasa, Sangihe and Talaoed, North Celebes, Central Celebes, Bali, Lombok, Soembawa, Flores, Soemba, Timor and surrounding islands, South Moluccas, and North Moluccas. The residencies were to be eliminated after the construction of functioning administration in the 13 regions. Complicating this structure was the fact that
More than 75% of the State of East Indonesia comprised autonomous regions, in total 115 autonomous regional governments under the rule of rajas
'. The position of these autonomous governmental heads was regulated by what were called korte verklaring and lange kontrakten ; these were actually intended as a recognition by the Dutch Indies Government of the special position of the rajas, whose power to govern the autonomous regions was handed down from one generation to the next.
The Autonomous Region Regulation of 1938 gave the swaprajas wide de jure autonomy but most of the rajas were puppets of Dutch administrators.The State of East Indonesia sought to curtail the power of these raja-ruled regions, but the Regulations for the Formation of the State of East Indonesia obliged the state to recognise their special status. The remaining area of the state not part of the swaprajas comprised directly governed regions . Directly governed areas included Minahasa, the South Moluccas, Gorontalo, the districts of Macassar and Bonthain, and Lombok.
