United States of Indonesia in the context of "Dutch–Indonesian Round Table Conference"

The Indonesian National Revolution (Indonesian: Revolusi Nasional Indonesia), also known as the Indonesian War of Independence (Indonesian: Perang Kemerdekaan Indonesia, Dutch: Indonesische Onafhankelijkheidsoorlog), 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) 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 State of East Indonesia (Indonesian: Negara Indonesia Timur, old spelling: Negara Indonesia Timoer, Dutch: Oost-Indonesië) was a post–World War II state formed in the eastern half of Dutch East Indies. Established in December 1946 by the Dutch, it was a puppet state formed during the Indonesian National Revolution that eventually became a part of the United States of Indonesia (USI) in 1949 at the end of the conflict and was dissolved in 1950 with the end of the USI. It comprised all the islands to the east of Borneo (Celebes and the Moluccas, with their offshore islands) and of Java (Bali and the Lesser Sunda Islands).

The Federal Consultative Assembly, (or Dutch: Bijeenkomst voor Federaal Overleg, BFO) was a committee established on 8 July 1948 to discuss the form of the planned federal United States of Indonesia. Its membership comprised the leaders of the various federal states established by the Dutch in the areas they occupied following their attack on the areas of Indonesia controlled by republican forces during the Indonesian National Revolution (1945–1949). It took part in negotiations with the Dutch in August and September 1948, and participated in the Dutch–Indonesian Round Table Conference at which the Dutch agreed to hand over sovereignty to the United States of Indonesia.

Banjar Region (Indonesian: Daerah Banjar, old spelling Bandjar) was an autonomous area formed in the southeastern part of Indonesian island of Borneo by the Netherlands in 1948 as part of an attempt to re-establish the colony of the Dutch East Indies during the Indonesian National Revolution. Banjar became a constituent part of the United States of Indonesia in 1949. The chairman of the Banjar Council was Mohammed Hanafiah. The region was dissolved on 4 April 1950 and combined with Great Dayak and the Southeast Borneo Federation to form Kalimantan Province. Today, the territory of the former region comprises around two thirds of South Kalimantan Province.
