## History

The Bulungan Regency was originally co-extensive with what subsequently became the province of North Kalimantan. On 8 October 1997 the town of Tarakan was cut out of the regency to become an independent city. Two years later, on 4 October 1999, the remaining territory of the regency was split to create two additional regencies - Malinau Regency and Nunukan Regency. On 17 July 2007, three more districts (kecamatan) was split from Bulungan Regency to form a new regency, Tana Tidung Regency.
Bulangan Regency had originally been part of the East Kalimantan province, but in 2012 it - together with the areas carved out of it in 1997, 1999 and 2007 - became part of the newly created North Kalimantan province. Tanjung Selor in Bulungan Regency was designated as the province's capital.
