The history of this place is very long. Long ago, Hindu and Buddhist kingdoms ruled the region. Later, these kingdoms changed into Muslim sultanates. The Malay people established the Sambas Sultanate in 1609. The Mempawah Sultanate was also formed in 1740. Chinese workers came to work in gold mines around 1750. A group called the Lanfang Republic was also founded by Chinese miners. This was an independent state that worked with local sultanates.

West Kalimantan is a major province located in the western part of Borneo. It is one of five Indonesian provinces that make up the Indonesian portion of the island. The province covers an area of 147,018 km2. This makes it the third largest province in Indonesia, following Papua and Central Kalimantan. To visualize its size, it is about 1.13 times the size of the island of Java. The province is bounded by the Malaysian state of Sarawak to the north. It shares land borders with East Kalimantan and Central Kalimantan to the east. To the west lie the Bangka Belitung Islands, and the Java Sea sits to the south.

The geography of the region is defined by its low-lying landscape and massive water systems. It is famously nicknamed "The Province of a Thousand Rivers." This name describes the hundreds of rivers that crisscross the land. Most of these rivers are navigable, meaning boats can travel through them. The Kapuas River is the most significant, serving as the longest river in Indonesia at 1,086 km. A huge portion of this river, 942 km, is navigable. Other major rivers include the Melawi, the Pawan, and the Sambas. These waterways act as the lifeblood for the region. They remain essential routes for transporting freight to the hinterland, even though roads now reach most districts.

Water also forms large, unique ecosystems in the province. There are two significant lakes located in the Kapuas Hulu area. Lake Sentarum is a massive wetland covering 117,500 hectares. During the dry season, this lake can become almost entirely dry.

The second major lake is Lake Luar I, which covers about 5,400 hectares. Beyond the mainland, the province includes dozens of islands. These are spread along the Karimata Strait and the Natuna Sea. Most of these islands are uninhabited. The province's terrain is mostly low and slightly hilly. It is flanked by the Kalingkang Mountains in the north and the Schwaner Mountains in the south. The highest point is Mount Baturaya, which reaches 2,278 metres above sea level.

The climate in West Kalimantan is tropical. This means the weather is often very hot and has high humidity. A unique feature of the province is the Equator. This imaginary line that divides the Earth into northern and southern hemispheres passes directly through the capital city, Pontianak.

The province is also notable for its land connectivity. It is the only Indonesian province with an official access road to a neighboring country. A 400 km road connects Pontianak to Kuching in Sarawak, Malaysia. This journey typically takes between six and eight hours.

History in the region began with Hindu and Buddhist kingdoms. Later, these kingdoms converted into Muslim sultanates. The Malays are the native Muslims of the area. They established the Sambas Sultanate in 1609. The Mempawah Sultanate was established in 1740 between Pontianak and Sambas. In the 1700s, these sultanates brought in workers from China. Some came to work in gold mines. This led to the creation of the Lanfang Republic. This was an autonomous state founded by Chinese miners. It functioned as a sub-state of the Qing dynasty and allied with local sultanates. The Dutch invasion in 1884 eventually ended the Lanfang government.

The 20th century brought significant changes and hardships. West Kalimantan was under Japanese occupation from 1942 to 1945. During this time, the "Pontianak incidents" occurred. Japanese troops kidnapped and killed more than 21,000 people in Pontianak. This included sultans and many local elites. Many victims were buried in large wells in Mandor. After the war, West Kalimantan transitioned through various political stages. It was part of a federal system before joining the Republic of Indonesia in 1950. The region also experienced periods of domestic conflict and ethnic violence in the late 20th century. These events involved different groups, including the Dayak, Malay, Chinese, Javanese, Bugis, and Madurese.

Today, the province is a diverse and growing region. The population has grown steadily over the years. In the 2010 Census, there were 4,395,983 people. By the 2020 Census, this rose to 5,414,390. Official estimates for mid-2025 placed the population at 5,766,030. The province is divided into twelve regencies and two cities. Pontianak serves as the capital and largest city. About 29 percent of the total population lives in the Greater Pontianak area. The province continues to be a vital part of the Indonesian archipelago.
