Davao City: History
=== Precolonial era ===
The area of what is now Davao City was once a lush forest inhabited by Lumadic peoples such as the Bagobos and Matigsalugs, alongside other ethnic groups such as the Aeta, Maguindanaon and the Kagan. Davao River was then called Tagloc River by the Bagobos, Maguindanaons and Tausugs who then inhabited a settlement near the mouth of the river to the sea around what is now Bolton Riverside due immediately southwest of the city plaza. In 1543, Spanish explorers led by Ruy Lopez de Villalobos sailing around Mindanao deliberately avoided the area around Davao Gulf, then called Gulf of Tagloc, due to the danger posed by fleets of Moro warships operating in the area while surveying the southeastern coast of Mindanao for possible colonization, and as a result the Davao Gulf area remained virtually untouched by European explorers for the next three centuries.
A Maguindanaon Datu under the name Datu Bago was rewarded the territory of the surroundings of Davao Gulf by the Sultan of Maguindanao Sultanate for joining the campaign against the Spanish in the late 1700s. From his ancestral home in Maguindanao, he moved to the area in 1800 and, having convinced Bagobos and other native groups in the area to his side, conquered the entire Davao Gulf area. Having consolidated his position, he founded the fortress of Pinagurasan in what is now the site of Bangkerohan Public Market in 1830 which served as his capital. From being a fortification and base of operations from which Datu Bago could gather and rally his forces, the settlement of Pinagurasan eventually grew into a small city extending from present-day Generoso Bridge in Bangkerohan to Quezon Boulevard more than a kilometer down south, as Maguindanaons and Bagobos alike among other nearby tribes in the area flocked into the settlement, eventually becoming the main trade entrepot in the Davao Gulf area. With his immense overlordship of Davao Gulf, Datu Bago was eventually crowned Sultan by his subjects at his capital Pinagurasan in 1843, effectively making his realm virtually independent from the Sultanate of Maguindanao, becoming a Sultanate with sovereignty over Davao Gulf in equal standing with the Muslim kingdoms of Maguindanao and Sulu. …
