The Indonesian National Revolution (Indonesian: Revolusi Nasional Indonesia), also known as the Indonesian War of Independence, was an armed conflict and diplomatic struggle between the Republic of Indonesia and the Dutch Empire and an internal social revolution during postwar and postcolonial Indonesia. It took place between Indonesia's declaration of independence in 1945 and the Netherlands' transfer of sovereignty over the Dutch East Indies to the Republic of the United States of Indonesia at the end of 1949.
The four-year struggle involved sporadic but bloody armed conflict, internal Indonesian political and communal upheavals, and two major international diplomatic interventions. Dutch military forces (and, for a while, the forces of the World War II allies such as the United Kingdom) were able to control the major towns, cities and industrial assets in Republican heartlands on Java and Sumatra but could not control the countryside. By 1949, international pressure on the Netherlands, the United States threatening to cut off all economic aid for World War II rebuilding efforts to the Netherlands and the partial military stalemate became such that the Netherlands transferred sovereignty over the Dutch East Indies to the Republic of the United States of Indonesia.
The revolution marked the end of the colonial administration of the Dutch East Indies, except for Dutch New Guinea. It also significantly changed ethnic castes as well as reducing the power of many of the local rulers (raja). It did not significantly improve the economic or political fortunes of the majority of the population, although a few Indonesians were able to gain a larger role in commerce.
Background
The Indonesian independence movement began on 20 May 1908, which is commemorated as the "Day of National Awakening" (Indonesian: Hari Kebangkitan Nasional). Indonesian nationalism and movements supporting independence from Dutch colonialism, such as Budi Utomo, the Indonesian National Party (PNI), Sarekat Islam and the Indonesian Communist Party (PKI), grew rapidly in the first half of the 20th century. Budi Utomo, Sarekat Islam and others pursued strategies of co-operation by joining the Dutch initiated Volksraad ("People's Council") in the hope that Indonesia would be granted self-rule. Others chose a non-cooperative strategy demanding the freedom of self-government from the Dutch East Indies colony.
The occupation of Indonesia by Japan for three and a half years during World War II was a crucial factor in the subsequent revolution. The Netherlands had minimal ability to defend its colony against the Japanese army, and within only three months of their initial attacks, the Japanese had occupied the Dutch East Indies. In Java, and to a lesser extent in Sumatra (Indonesia's two dominant islands), the Japanese spread and encouraged nationalist sentiment. Although this was done more for Japanese political advantage than from altruistic support of Indonesian independence, this support created new Indonesian institutions (including local neighbourhood organisations) and elevated political leaders such as Sukarno. Just as significantly for the subsequent revolution, the Japanese destroyed and replaced much of the Dutch-created economic, administrative, and political infrastructure.
On 7 September 1944, with the war going badly for the Japanese, Prime Minister Koiso promised independence for Indonesia, but no date was set. For supporters of Sukarno, this announcement was seen as vindication for his collaboration with the Japanese.
History
Japanese surrender
Proclamation of Indonesian Independence
The unconditional surrender of Japan on August 15, 1945 was eagerly received by the radical and politicised pemuda (Indonesian for 'male youth') groups. They pressured Sukarno and Hatta to proclaim Indonesian independence on 17 August 1945, two days later. The following day, the Preparatory Committee for Indonesian Independence (PPKI) elected Sukarno as president, and Hatta as vice-president.
PROCLAMATION
We, the people of Indonesia, hereby declare the independence of Indonesia.
Matters which concern the transfer of power and other things will be executed by careful means and in the shortest possible time.
Djakarta, 17 August 1945
In the name of the people of Indonesia,
[signed] Soekarno—Hatta
(translation by the Ministry of Foreign Affairs, October 1948)
Revolution and Bersiap
It was mid-September before news of the declaration of independence spread to the outer islands, and many Indonesians far from the capital Jakarta did not believe it. As the news spread, most Indonesians came to regard themselves as pro-Republican, and a mood of revolution swept across the country. External power had shifted; it would be weeks before Allied Forces shipping entered Indonesia (owing in part to boycotts and strikes, in Australia, on coaling, loading and manning Dutch shipping from Australia, where the Netherlands East Indies Government in exile was based). These strikes were only fully broken in July 1946. The Japanese, on the other hand, were required by the terms of the surrender to both lay down their arms and maintain order; a contradiction that some resolved by handing weapons to Japanese-trained Indonesians.
The resulting power vacuums in Java and Sumatra in the weeks following the Japanese surrender created an atmosphere of uncertainty, but also one of opportunity for the Republicans. Many pemuda joined pro-Republic struggle groups (badan perjuangan). The most disciplined were soldiers from the Japanese-formed but disbanded Giyūgun (PETA, volunteer army) and Heiho (local soldiers employed by Japanese armed forces) groups. Many groups were undisciplined, due to both the circumstances of their formation and what they perceived as revolutionary spirit. In the first weeks, Japanese troops often withdrew from urban areas to avoid confrontations.
By September 1945, control of major infrastructure like railway stations and trams in Java's largest cities had been taken over by Republican pemuda, such as the Railway Youth Force, who encountered little Japanese resistance. To spread the revolutionary message, pemuda set up their own radio stations and newspapers, and graffiti proclaimed the nationalist sentiment. On most islands, struggle committees and militia were set up. Republican newspapers and journals were common in Jakarta, Yogyakarta, and Surakarta, which fostered a generation of writers known as angkatan 45 ('generation of 45') many of whom believed their work could be part of the revolution.
Republican leaders struggled to come to terms with popular sentiment; some wanted passionate armed struggle; others a more reasoned approach. Some leaders, such as the leftist Tan Malaka, spread the idea that this was a revolutionary struggle to be led and won by the Indonesian pemuda. Sukarno and Hatta, by contrast, were more interested in planning government and institutions to achieve independence through diplomacy. Pro-revolution demonstrations took place in large cities, including one in Jakarta on 19 September with over 200,000 people, which Sukarno and Hatta, fearing violence, successfully quelled.
By September 1945, many of the self-proclaimed pemuda, who were ready to die for '100% freedom', were getting impatient. It was common for ethnic 'out-groups' – Dutch internees, Eurasian, Ambonese, Chinese, Minahasans, well-off Natives – and anyone considered or accused to be a spy, to be subjected to intimidation, kidnapping, robbery, murder and organised massacres. Such attacks would continue throughout the course of the revolution, but were most present during the 1945–46 period, which is known as the Bersiap.
Estimates of the death toll of the Bersiap period vary from 3,500 to 30,000. NIOD concluded a Dutch casualty number of approximately 5,500 with possible higher numbers but not above 10,000. Estimates of the number of Indonesian fighters killed in the lead up to and during the Battle of Surabaya range from 6,300 to 15,000. The Japanese forces lost around 1,000 soldiers and the British forces registered 660 soldiers, mostly British Indians, as killed (with a similar number missing in action).
Formation of the Republican government
By the end of August 1945, a central Republican government had been established in Jakarta. It adopted a constitution drafted during the Japanese occupation by the Preparatory Committee for Indonesian Independence. With general elections yet to be held, a Central Indonesian National Committee (KNIP) was appointed to assist the President. Similar committees were established at provincial and regency levels.
Questions of allegiance immediately arose amongst indigenous rulers. Central Javanese principalities, for example, immediately declared themselves Republican, while many raja ('rulers') of the outer islands, who had been enriched from their support of the Dutch, were less enthusiastic. Such reluctance among many outer islands was sharpened by the radical, non-aristocratic, and sometimes Islamic nature of the Java-centric Republican leadership. Support did, however, come from South Sulawesi (including the King of Bone, who still recalled battles against the Dutch from early in the century), and from Makassarese and Bugis raja, who supported the Republican Governor of Jakarta, a Menadonese Christian. Many Balinese raja accepted Republican authority.
Fearing the Dutch would attempt to re-establish their authority over Indonesia, the new Republican Government and its leaders moved quickly to strengthen the fledgling administration. Within Indonesia, the newly formed government, although enthusiastic, was fragile and focused in Java (where focused at all). It was rarely and loosely in contact with the outer islands, which had more Japanese troops (particularly in Japanese naval areas), less sympathetic Japanese commanders, and fewer Republican leaders and activists. On 14 November 1945, a parliamentary form of government was established and Sjahrir was appointed prime minister.
In the week following the Japanese surrender, the Giyūgun (PETA) and Heiho groups were disbanded by the Japanese. Command structures and membership vital for a national army were consequently dismantled. Thus, rather than being formed from a trained, armed, and organised army, the Republican armed forces began to grow in September from usually younger, less trained groups built around charismatic leaders. Creating a rational military structure that was obedient to central authority from such disorganisation, was one of the major problems of the revolution, a problem that remains through to contemporary times. In the self-created Indonesian army, Japanese-trained Indonesian officers prevailed over those trained by the Dutch. A thirty-year-old former school teacher, Sudirman, was elected 'commander-in-chief' at the first meeting of Division Commanders in Yogyakarta on 12 November 1945.
Allied situation (1945)
The Dutch accused Sukarno and Hatta of collaborating with the Japanese, and denounced the Republic as a creation of Japanese fascism. The Dutch East Indies administration had just received a ten million dollar loan from the United States to finance its return to Indonesia.
Allied occupation
The Netherlands, however, was critically weakened from World War II in Europe and did not return as a significant military force until early 1946. The Japanese and members of the Allied forces reluctantly agreed to act as caretakers. Australian forces of I Corps under general Leslie Morshead had landed in Borneo in May 1945, to destroy the Imperial Japanese forces stationed there, as well as maintaining order on the island until the Dutch could return. As US forces were focusing on the Japanese home islands, the archipelago was put under the jurisdiction of British Admiral Earl Louis Mountbatten, the Supreme Allied Commander, South East Asia Command. Allied enclaves already existed in Kalimantan (Indonesian Borneo), Morotai (Maluku) and parts of Irian Jaya; Dutch administrators had already returned to these areas. In the Japanese navy areas, the arrival of Allied troops quickly prevented revolutionary activities where Australian troops, followed by Dutch troops and administrators, took the Japanese surrender (except for Bali and Lombok). Due to the lack of strong resistance, two Australian Army divisions succeeded in occupying eastern Indonesia.
The British were charged with restoring order and civilian government in Java. The Dutch took this to mean pre-war colonial administration and continued to claim sovereignty over Indonesia. The British and Indian troops did not, however, land on Java to accept the Japanese surrender until late September 1945. Lord Mountbatten's immediate tasks included the repatriation of some 300,000 Japanese, and freeing prisoners of war. He did not want, nor did he have the resources, to commit his troops to a long struggle to regain Indonesia for the Dutch. The first British troops reached Jakarta in late September 1945, and arrived in the cities of Medan (North Sumatra), Padang (West Sumatra), Palembang (South Sumatra), Semarang (Central Java) and Surabaya (East Java) in October. In an attempt to avoid clashes with Indonesians, the British commander Lieutenant General Sir Philip Christison diverted soldiers of the former Dutch colonial army to eastern Indonesia, where Dutch reoccupation was proceeding smoothly. Tensions mounted as Allied troops entered Java and Sumatra; clashes broke out between Republicans and their perceived enemies, namely Dutch prisoners, Dutch colonial troops (KNIL), Chinese, Indo-Europeans and Japanese.
