Bersiap
phase of the Indonesian National Revolution (1945–1947)
In Indonesian historiography, the term Bersiap ("Get ready" or "Be prepared" in English) refers to the violent and chaotic beginning of the Indonesian National Revolution following the end of World War II in Asia. In Indonesia, the term Berdaulat ("Sovereign") is also used for this transitional period. It began after Sukarno's proclamation of Indonesian Independence on 17 August 1945 and culminated during the power vacuum between the withdrawal of Japanese occupational forces and the gradual buildup of a British military presence, before the official handover to a Dutch military presence in March 1946.
Thousands of European and Indo-European people were killed by native Indonesians. Many non-Europeans accused of anti-revolutionary or pro-Dutch sentiment also fell victim to violence, such as Chinese civilians, Japanese and Korean prisoners of war, as well as native Indonesians such as the Moluccans, Ambonese, Minahasans and Timorese along with Javanese people, Bantenese people, Malays, Minangkabau people and Batak people of higher social and economic standing. The violence led to forced repatriation and the proliferation of a worldwide Indo-European diaspora.
Instances of wanton violence had decreased by the time British forces withdrew in 1946 and after the Dutch had rebuilt their military capacity in the region, though revolutionary and intercommunal killings continued into 1947. Meanwhile, the Indonesian revolutionary fighters were well into the process of forming a formal military and stemming violent excesses. The last troops of the former Imperial Japanese Armed Forces had been evacuated by July 1946.
Term
The term Bersiap is derived from the battle cry and perpetual call to arms "Siap!" ("Get ready!" or "Be prepared!"), uttered by Indonesian nationalists when potential enemies of the revolution entered pro-republican areas.
This brief starts where responsible research should: with the source description of “Bersiap” as phase of the Indonesian National Revolution (1945–1947). Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the history & society register because the source frames it as phase of the Indonesian National Revolution (1945–1947). Its deeper value depends on whether names, dates, institutions and citations support that framing.
Contemporary correspondence, administrative files and participant testimony can test how later narratives organized the event or institution. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q4894934. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1945, 1946 and 1947.
Official terminology may obscure informal participation, dissent or communities documented only indirectly. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
