This event is known in Indonesia as the 4 January 1946 Incident (Indonesian: Peristiwa 4 Januari 1946) because the entire cabinet of Indonesia had fully arrived in Yogyakarta on 4 January 1946 after the President and Vice President of Indonesia had arrived the previous day. Situated during the Indonesian National Revolution, it was the first time the Indonesian government relocated the national capital from Jakarta to another city.
