The Socialist Party of Indonesia was a political party in Indonesia from 1948 until 1960, when it was banned by President Sukarno.
Guided Democracy, also called the Old Order, was the political system in place in Indonesia from 1959 until the New Order began in 1966. This period followed the dissolution of the liberal democracy period in Indonesia by President Sukarno, who centralized control in the name of political stability. He claimed to have based the system based on the traditional village system of discussion and consensus, which occurred under the guidance of village elders. On the national level, however, this meant centralized rule under Sukarno: martial law, a massive reduction in civil liberties and democratic norms, and the Indonesian National Armed Forces and Communist Party of Indonesia acting as major power blocs.
An exclusive mandate is a government's assertion of its legitimate authority over a certain territory, part of which another government controls with stable, de facto sovereignty.

The period began on 17 August 1950 following the dissolution of the federal United States of Indonesia, less than a year after its formation, and ended with the imposition of martial law and President Sukarno's decree, which resulted in the introduction of the Guided Democracy period on 5 July 1959.
Annexation, in international law, is the forcible acquisition and assertion of legal title over one state's territory by another state, usually following military occupation of the territory.
