At the beginning of the Indonesian independence in 1945, the West Sumatra region was incorporated in the Sumatra province based in Bukittinggi. Four years later, Sumatra Province was divided into three provinces, namely North Sumatra, Central Sumatra, and South Sumatra. West Sumatra, Riau and Jambi were part of the residency within the Province of Central Sumatra. During the PRRI period, based on emergency law number 19 of 1957, Central Sumatra Province was further divided into three provinces namely West Sumatra Province, Riau Province, and Jambi Province. The Kerinci region which was previously incorporated in the South Sumatra Regency of Kerinci, was incorporated into Jambi Province as a separate regency. Likewise, the Kampar, Rokan Hulu and Kuantan Singingi areas are designated as part of Riau Province.
