Overview
Mapun, officially the Municipality of Mapun, is an island municipality in the Philippine province of Tawi-Tawi. It occupies Mapun Island and surrounding islets in the Sulu Sea, near Sabah, Malaysia, and southwest of the main Philippine island groups. The municipality is home to the Jama Mapun, or “people of Mapun,” whose local language is Pullun Mapun. Although the supplied subject is not a commercial brand, Mapun functions as a geographic and cultural identity associated with the municipality, its people, language, traditions, local economy, and political history. The island was historically known as Cagayan de Sulu and later as Cagayan de Tawi-Tawi. The present name, Mapun, reflects the community’s own cultural and linguistic identity. The municipality consists of 15 barangays, including Liyubud, which contains the poblacion, as well as Boki, Duhul Batu, Guppah, Iruk-Iruk, Kompang, Lubbak Parang, Lupa Pula, Mahalu, Pawan, Sapah, Sikub, Tabulian, Tanduan, and Umus Mataha. Several smaller islands and islets surround the main island, including Manda, Boan, Kinapusan, Pamilikan, Lapun-Lapun, Bintuut, and Muligi. Mapun’s history is closely connected with maritime movement and trade in the Sulu Archipelago. Sama-Bajau communities occupied the island during the late eighteenth and early nineteenth centuries, while Tausug communities also maintained a presence. The island was known as a source of rice and sago and participated in regional exchange networks. In the late eighteenth century, foreign trading vessels visited Cagayan de Sulu, while local prahus continued to travel between the island, southern Palawan, Sulu, Labuan, and other ports despite Spanish efforts to restrict Tausug maritime commerce. Mapun’s unusual colonial history was shaped by a boundary error associated with the 1898 Treaty of Paris. Unlike most of the Philippine archipelago, Cagayan de Sulu and Sibutu remained under Spanish sovereignty until a subsequent agreement transferred them to the United States in 1901. During the American period, the island was administered through a distinctive local arrangement rather than being organized immediately as a regular municipality. Guy Stratton, an American resident governor, helped consolidate local districts under a common administrative authority and established an administrative center at Lupa Pula. Datu Amilhanja served as mayor from 1911 to 1914 under the colonial system. During the Japanese occupation, Salip Hatari of Awang became the island’s de facto ruler from 1943 to 1945 with Japanese support. After Philippine independence in 1946, the island remained part of the Philippines. In 1959, national legislation converted Cagayan de Sulu from a municipal district into a municipality. It later became part of the newly established province of Tawi-Tawi. The name changed to Cagayan de Tawi-Tawi in 1984 and to Mapun in 1988. The contemporary municipality has a predominantly maritime and agricultural economy. Fishing, farming, coconut cultivation, and copra production are important sources of livelihood. Coconut trees occupy a substantial portion of the island’s cultivated land, and copra is traded for processing in larger commercial centers such as Palawan and Zamboanga City. Because irrigation is limited, rice is generally brought in from elsewhere, including Palawan, Zamboanga, and Malaysia, while cassava is an important local staple. The municipality’s location also gives it significance as a stopping and trading point for maritime traffic connected with northern Borneo, Sabah, and Labuan. Mapun has a small but culturally active population. The 2024 Philippine census recorded 29,218 residents. Education is provided through elementary and secondary schools, including Notre Dame of Cagayan, Tawi-Tawi Academy, Mapun Senior High School, and institutions associated with Mindanao State University. Many students pursue further education outside the municipality, particularly in Bongao, Zamboanga City, and Palawan. Mapun Day, or Mapun Foundation Day, is celebrated annually beginning September 1 and culminating on September 5. Activities include parades, music and dance competitions, religious and literary performances, traditional dances such as pangalay and lunsay, and the Budjang Mapun beauty contest. These events reinforce Mapun’s identity as a distinct Jama Mapun community within Tawi-Tawi.
History
Mapun’s recorded history reflects the overlapping influence of Sama-Bajau, Tausug, Spanish, American, Japanese, and independent Philippine authorities. In the late eighteenth and early nineteenth centuries, the island was occupied primarily by Sama-Bajau communities and also had a smaller Tausug population. It participated in the Sulu Archipelago’s maritime economy, supplying rice and sago and exchanging agricultural goods, coconuts, and other products with neighboring islands and ports. An East India Company vessel, the Antelope, spent time trading around Cagayan de Sulu and the Tapian Tana islands in 1783. During the nineteenth century, the island remained connected to commercial routes linking southern Palawan, Sulu, Labuan, and British settlements in northern Borneo. Spanish military efforts to suppress Tausug shipping after the conquest of Jolo disrupted these networks. Nevertheless, trading boats continued to operate, and the island remained important to regional food and maritime exchange. Mapun’s legal status was complicated by the 1898 Treaty of Paris. The treaty did not initially transfer Cagayan de Sulu and Sibutu to the United States with the rest of the Philippines. A later agreement, ratified in 1901, formally included the islands in the territory administered by the United States. American records described Cagayan Sulu as a sparsely populated island group with favorable conditions for crops, but with residents relying heavily on fishing and imported rice. The island was not initially organized as a standard municipality of the Moro Province’s Sulu District. Instead, it operated through a tribal ward-style arrangement. Guy Stratton became the first American resident governor and remained on the island for almost two decades. He consolidated several districts and villages under one local authority and established an administrative center at Lupa Pula. Datu Amilhanja served as mayor from 1911 to 1914. During the Japanese occupation, Salip Hatari of Awang acted as the island’s de facto ruler from 1943 to 1945 with Japanese assistance. Philippine independence in 1946 placed Mapun within the independent Republic of the Philippines. Executive Order No. 355 converted Cagayan de Sulu from a municipal district into a municipality, with the change taking effect in 1958 and the first municipal election held in 1959. Lim Eng, who had previously been appointed in 1954, became the first elected mayor and served until 1967. The island was transferred into the province of Tawi-Tawi after that province was separated from Sulu. Its official name changed first to Cagayan de Tawi-Tawi in 1984 and then to Mapun in 1988 through national legislation. Modern Mapun remains shaped by its position near the Philippine-Malaysian maritime boundary. Fishing and farming are central economic activities, with coconut cultivation and copra trade especially important. The island’s waters lie within the Sandakan Basin, an area associated with hydrocarbon exploration, and Philippine-side exploration has taken place since the early twenty-first century. Mapun also serves as a point of interest for traders and vessels traveling toward Sabah and Labuan. Cultural life centers on the Jama Mapun community, the Pullun Mapun language, Islamic practice, traditional dances, and the annual Mapun Day celebration.

Products and positioning
A geographically remote Philippine island municipality positioned around Jama Mapun cultural identity, maritime connections, fishing, coconut agriculture, and trade across the Sulu Sea.
Agricultural commodities
Coconut and copra
Coconut cultivation is one of Mapun’s principal economic activities. Coconuts are harvested periodically and processed or traded as copra, with shipments moving to larger commercial and refining centers outside the municipality, including Palawan and Zamboanga City.
Fishing
Fish and marine products
Fishing is a major source of food, employment, and household income. Mapun’s island setting and location in the Sulu Sea support local fishing and connect the municipality with wider maritime trading routes.
Agricultural products
Cassava and local crops
Cassava is an important local staple because rice production is constrained by limited irrigation. Other crops and garden produce are cultivated for local consumption and exchange, while much of the municipality’s rice supply is imported from nearby Philippine regions or Malaysia.
