From federalism to a unitary state: Indonesia's path to central power

In short: Indonesia's journey to a unified government wasn't a straight line. It involved a brief experiment with federalism, a period of intense political instability, and a radical shift toward a centralized system that remains the backbone of the nation's governance today.

The Republic of the United States of Indonesia emerged as a federal state in 1949 after the fight against Dutch rule concluded. However, this structure was short-lived. A unanimous vote by federated authorities in 1950 saw the nation revert to a 'unitary' structure and the title Republic of Indonesia. This move shifted the nation toward a more centralized authority, a structure that has largely persisted since the reinstatement of the 1945 constitution. The provisional capital during the revolution was established in Yogyakarta. This period followed the 1945 declaration of jurisdiction over the former Dutch East Indies. The transition occurred despite the Netherlands retaining possession of large areas like Papua.

The country's governance has been marked by distinct ideological eras. The period of Liberal Democracy (1950–1959) was characterized by extreme political instability, where no cabinet lasted longer than two years. In 1959, President Sukarno introduced "Guided Democracy," rejecting Western models in favor of a system inspired by traditional village consensus. This era ended in 1966, making way for Suharto's "New Order," a 31-year presidency that followed the ousting of Sukarno. During the 1950s, the nation hosted the landmark 1955 Bandung Conference. Sukarno attempted to balance the antagonistic forces of the army and the Indonesian Communist Party. By 1965, the Communist Party had gained significant influence across all levels of government.

Today, the 1945 constitution concentrates significant power in the executive branch, specifically the president. While the People’s Consultative Assembly (MPR) serves as the legislative body, the president acts as the supreme commander of the armed forces and holds the authority to issue regulations and international agreements. Since 2004, the system has evolved to include direct presidential elections and a bicameral legislature, balancing central authority with a complex web of over 30 provinces and thousands of local subdivisions. The president is supported by a cabinet and a non-binding Supreme Advisory Council. A presidentially appointed Supreme Audit Board manages state finances. The legislative body is split into a lower house and an upper house, with the lower house holding about four-fifths of the seats.
