History
As created, Jayawijaya Regency covered an area coincident with the whole of what in 2022 became Highland Papua Province. However, on 11 December 2002 three new Regencies - Bintang Mountains Regency (Kabupaten Pegunungan Bintang), Tolikara Regency, and Yahukimo Regency - were created from parts of Jayawijaya Regency. Subsequently on 4 January 2008 another four new Regencies - Lanny Jaya Regency, Central Mamberamo Regency (Kabupaten Mamberamo Tengah), Nduga Regency, and Yalimo Regency - were created from further parts of Jayawijaya Regency. All eight regencies were brought together again in 2022 in the new province of Highland Papua.
