Wao, Lanao del Sur

Wao officially the Municipality of Wao (Maranao/Iranun: Inged a Wao; Lungsod sa Wao; Bayan ng Wao), is a 2nd class municipality in the province of Lanao del Sur, Philippines. According to the 2020 census, it has a population of 50,366 people. Wao is the only Christian-majority municipality of its province.

Etymology
There are three possible etymology for the name of the municipality Wao. One is a local folklore which involved Bai Sa Raya, a Moro princess from a monarchy in Cotawato visited the area which is now known as "Wao" coincidentally during a serious drought. This led to the place to being called Wao from the word kawaw or uhaw in the local language which roughly translates to "I am thirsty". Another theory is that the place was named after a former creek in Eastern Wao which was extant prior to the arrival of Christian settlers in the 1950s. A third theory is that the name of the town was derived from the Maranao word liawao which means "high place", this is a reference to a Moro settlement existing in the current-day poblacion during the pre-1950 settlement era. Other nearby settlements are situated at a lower elevation that Liawao.

History
The LASEDECO resettlement program of then-President Ramon Magsaysay made possible the foundation of Wao as a municipality in Lanao del Sur province on February 22, 1961. The first settlers in the area were sixty families of various ethnicity from the then-undivided Cotabato province. Only one person, Elvino B. Balicao Sr. among the 1st batch of settlers became one of the Municipal Mayors of Wao. Balicao, along with members of the 1st batch of 60 settlers that included the late couple Aludio and Sofia Emborgo, were welcomed by the native Muslim inhabitants of Wao led by Sultan Mamaco Saripada, the municipality's first appointed and elected mayor, Datu Tao Pagul and Datu Maki Saripada. They were treated to a sit-down meal in the house of Sultan Mamaco Saripada.

In the late 1970s, the town experienced intercommunal violence between its native Moro community and the Christian settlers. Tensions arose after Bumbaran (now known as Amai Manabilang) was created from Wao by President Ferdinand Marcos through Presidential Decree No. 1243 in November 17, 1977.

In 2024, a new municipality named Pilintangan or Saripada was proposed to be carved from Wao in the Bangsamoro Parliament, which would entail the loss of 11 barangays. This proposal was met with protests and opposition, fearing that this might cause a repeat of the violence the town experienced in the 1970s. Wao's mayor, Elvino Balicao Jr., also warned that the division would reduce the town into a third-class municipality due to reduced revenues and with most of its government buildings being located in the barangays to be separated.
