## History

On 5 February 1963, the administrative centre of Pontianak Regency was moved from Pontianak to Mempawah based on Minister of General Government and Regional Autonomy Decree No. Des.52/1/9-11 (Surat Keputusan Menteri Pemerintahan Umum Otonomi Daerah Nomor Des.52/1/9-11).
Based on Government Regulation No. 58 of 2014 (Peraturan Pemerintah Nomor 58 Tahun 2014), Pontianak Regency was formally renamed Mempawah Regency after the name of its administrative centre.

On 1 April 1961, a new district named Sungai Ambawang was established from the northern part of Sungai Raya district. On 17 June 1996, Meranti district was established by split off from the northeastern part of Menyuke district. On 25 March 1999, three new districts were established (Kuala Mandor B was cut out from the northern part of Sungai Ambawang district, Kuala Behe and Sebangki districts were cut out from the southern parts of Air Besar and Sengah Temila districts, respectively). When Landak Regency was established in the same year, the north-eastern districts (including Kuala Behe and Sebangki, which were established few months earlier) were became part of the newly-created regency.
In 2001, a new district named Rasau Jaya was established from the eastern part of Sungai Kakap district.

The following year, another two districts were created (Sadaniang district was cut out from the western part Toho and Mempawah Timur was cut out from the eastern part of Mempawah Hilir).
