Indonesia

Historical overview

Indonesia’s history reflects centuries of maritime trade, regional kingdoms, Islamic sultanates, European colonial expansion and a long independence struggle. The Dutch East India Company expanded Dutch influence from the seventeenth century, and the Netherlands gradually established colonial control over the Indonesian archipelago.

The early twentieth century saw the growth of modern nationalist organisations. Budi Utomo, founded in 1908, is often treated as an important marker of organised Indonesian nationalism. The Youth Pledge of 28 October 1928 articulated a shared commitment to one homeland, one nation and one language: Indonesia.

Japan occupied the Dutch East Indies during the Second World War. Following Japan’s surrender in August 1945, Sukarno and Mohammad Hatta proclaimed Indonesian independence on 17 August 1945. The Netherlands attempted to re-establish colonial authority, leading to armed conflict and diplomatic negotiations. Dutch sovereignty transfer to the United States of Indonesia took place on 27 December 1949.

Indonesia’s early republic experienced parliamentary instability and regional rebellions. President Sukarno introduced Guided Democracy in 1959. The political crisis of 1965–66 led to the destruction of the Indonesian Communist Party and mass killings. The scale, responsibility and local patterns of violence have been studied by historians and human-rights researchers; figures should always be attributed to the source used.

Suharto consolidated power and established the New Order regime, which lasted until 1998. Economic growth coexisted with political repression, restrictions on opposition and serious human-rights abuses. The Asian Financial Crisis and mass protests in 1998 led to Suharto’s resignation on 21 May. The Reformasi period that followed brought political liberalisation, constitutional amendments, decentralisation and direct presidential elections.

The National Archives of Indonesia (ANRI) is especially important for this collection. Its institutional history documents how archival collections changed hands during the independence struggle and the transfer of sovereignty. Arsip Nasional Republik Indonesia
