The Samarahan Division was formed on July 24, 1986 through the merging of three districts; Simunjan; Serian; and Samarahan. Before the official date of formation, all the three districts were under the administration of Kuching Division. Historically, the Simunjan district has been in existence since 1901 while the Serian district was formed back in 1955. Additionally, Samarahan was a small district known locally as Muara Tuang while it was under the administration of Kuching Division. In accordance with fast development in the area, the small district of what was known as Muara Tuang eventually was upgraded to a full-status district on August 19, 1983 which saw its name being changed to Samarahan District situated in Kota Samarahan.
As time passes by and the area sees more development, the name Muara Tuang of what it was known was changed to Kota Samarahan. Several years later on January 1st, 2002, the small district of Asajaya (Nonok) and Sadong Jaya (Pendam) which were under the administration of Simunjan District were merged and its status was also changed from a small district to a full-status district known as Asajaya District. Thus, since January 1st, 2002, the Samarahan Division covers four full-status districts of Simunjan, Serian, Samarahan, and Asajaya and two small districts of Sebuyau and Tebedu.
With the establishment of Samarahan Division, the small district of Sebuyau which was once under the administration of Sri Aman (Second Division), experienced its changed of governance as it was placed under the administration of Simunjan District. One of the factors that contribute to this is ease of access in terms of communication and road network between Sebuyau and Simunjan. Additionally, all major towns in the districts are connected with networks of paved roads which has made travelling to the Samarahan Resident Office a lot easier.
Furthermore, the networks of paved roads have also created abundance of economic activities for the people such as in the plantation industries as well as the influx of merchant items coming in and out of Samarahan Division.
Samarahan devision covers an area of 4,967.85 KM² wide with a diverse population of 219,300 during a population census on 2006. Each district in the division has a different area size and population diversity. The Samarahan district covers an area of 407.08 KM² with a population of 48,000 while Serian district covers an area of 2,039.89 KM² with the highest population of 82,000. Simunjan is the largest district in the division with an area of 2,217.67 KM² but less populated with only 38,000 population. The smallest district is Asajaya that covers an area of 302.82 KM² with a population of 29,000.
Early in the years of its establishment, the Samarahan Division was considered an outskirt town with few basic infrastructures catering the needs of its people. However, 21 years later in present time, Samarahan Division has seen a lot of improvements and developments of its infrastructures and surrounding areas. Furthermore, Kota Samarahan has been made the administration centre of Samarahan Division which is also called the City of Knowledge. Kota Samarahan as it is known as The City of Knowledge, where one can find various higher learning institutions such as Universiti Malaysia Sarawak (UNIMAS), Universiti Teknologi Mara (UiTM), Institute of Teacher Education (IPG) Tun Abdul Razak Campus, Kota Samarahan, and Industrial Training Institute Kota Samarahan (Institut Latihan Perindustrian Kota Samarahan).
The year 2002 is a historic year when the administration of Sebuyau district was taken over by Administrative Division of Samarahan after it was recognised as a division. Before the change of administration, the Sebuyau district was under the administration of Sri Aman Division.
The small district of Sebuyau is unique as it is strategically located between Sri Aman Division and Simunjan district while it is only 80.5 kilometres away from the capital city of Sarawak, Kuching city.
