Sjafruddin Prawiranegara established the Emergency Government of the Republic of Indonesia (Pemerintah Darurat Republik Indonesia, PDRI) in West Sumatra.

Sjafruddin Prawiranegara was an Indonesian statesman and economist. He served in various roles during his career, including as head of government in the Emergency Government of the Republic of Indonesia, as Minister of Finance in several cabinets, and as the first Governor of Bank Indonesia. Sjafruddin later became the prime minister of the Revolutionary Government of the Republic of Indonesia, a shadow government set up in opposition to the country's central government.

The Emergency Government of the Republic of Indonesia was established by Indonesian Republicans after the Netherlands occupied the at the time capital city of Yogyakarta in Central Java, the location of the temporary Republican capital during the Indonesian National Revolution. It was established in the city of Bukittinggi and led by Sjafruddin Prawiranegara.

West Sumatra is a province of Indonesia. It is on the west coast of the island of Sumatra and includes the Mentawai Islands off that coast. West Sumatra borders the Indian Ocean to the west, as well as the provinces of North Sumatra to the north, Riau to the northeast, Jambi to the southeast, and Bengkulu to the south. The province has an area of 42,119.54 km² (16,262.45 sq mi), or about the same size as Switzerland or Penza Oblast, with a population of 5,534,472 at the 2020 census. The official estimate at mid 2023 was 5,757,210. The province is subdivided into twelve regencies and seven cities. It has relatively more cities than other provinces outside Java, although several of them are relatively low in population compared with cities elsewhere in Indonesia. Padang is the province's capital and largest city.
