The province of Central Java was formalised on 15 August 1950, excluding Yogyakarta but including Surakarta. There have been no significant changes in the administrative division of the province ever since. In the aftermath of the 30 September Movement in 1965, an anti-communist purge took place in Central Java, in which the army and community vigilante groups killed Communists and leftists, both actual and alleged. Others were interned in concentration camps, the most infamous of which was on the isle of Buru in Maluku, first used as a place of political exile by the Dutch. Some were executed years later, but most were released in 1979 In 1998, near the downfall of longtime president Suharto, anti-Chinese violence broke out in Surakarta (Solo) and surrounding areas, in which Chinese property and other buildings were burnt down. The following year, public buildings in Surakarta were burnt by supporters of Megawati Sukarnoputri after Indonesia's parliament chose Abdurrahman Wahid instead of Megawati for the presidency.
