# Tandubas

Tandubas, officially the Municipality of Tandubas (Tagalog: Bayan ng Tandubas), is a municipality in the province of Tawi-Tawi, Philippines. According to the 2020 census, it has a population of 34,316 people.

## Etymology

The word Tandubas coined from two Malay words Tanjung Bas. Tanjung means “place”, while the word Bas means “Landing”. Therefore, Tandubas means a place of landing, referring to a group of Malaysian traders who sailed across many islands and landed on an island what is now Tandubas Island. Seeing the abundance of resources to sustain their living, this group of Malaysian traders finally decided to settle on that island and named it as Tanjung Bas.
For many years, the island had been named as Tanjung Bas. The Malaysian word Tanjung has its equivalent in Sama dialect which is Tandu. The name Tanjungbas has been changed by the natives to Tandubas, a name that was used from generation to generation.

## History

Tandubas had been a part of the Sultanate of Sulu prior to the creation of Sulu as a province under the Republic of the Philippines. When the province of Sulu was created, Tandubas was one of the Districts, an administrative sub-division of the then Department of Education under the Division of Sulu. By virtue of Executive Order No. 355, dated July 1, 1958, Tandubas was converted to a Municipality under the Province of Sulu, covering areas now under the municipality of Sapa-Sapa, the municipality of Languyan, an area in the mainland of Tawi-Tawi. When the Province of Tawi-Tawi was created by virtue of Presidential Decree No. 302, dated September 27, 1973, the Municipality of Tandubas became one of the municipalities in the Province of Tawi-Tawi.
By 2008, the municipality celebrated its Golden Anniversary. In a bid to create more local government units that comprise the Province of Tawi-Tawi, the Municipality of Sapa-Sapa was created entirely from Tandubas Municipality. Also the Municipality of Languyan was created partly out of the territorial jurisdiction of the Municipality of Tandubas, thus greatly reducing the land area of the mother municipality. This was made possible by virtue of Presidential Decree No. 1086.
