The Dayak Desa War or Majang Desa War was an armed uprising by the Dayak Desa tribe, and later Indonesian nationalists, in West Kalimantan against the Japanese Empire and the Dutch East Indies during World War II. The war was initially caused by the local population's opposition against the rōmusha system and disappointment with Japanese occupation. In the initial phase of Japanese occupation, several Japanese companies entered the region to gain natural resources in order to support the Japanese war effort in the Pacific. Occupying Japanese forced locals to work for free for these companies, mainly in coal mining and timber production. After that, a Japanese foreman working in a company wanted to marry the daughter of Pang Linggan, a respected Dayak chief in the region, which caused more tension between locals and the Japanese. Dayak tribes in the region initiated mangkuk merah ritual, as a sign to mobilise men from villages and prepare for war. The Japanese were driven out of the Borneo interior in June 1945, but returned on 17 July and continued until 31 August 1945 when Japanese forces there surrendered and left the region, replaced by Allied forces including the Dutch, who would later be opposed again until recognition of Indonesian independence in 1949.
