This document provides a history of Zamboanga City in the Philippines from pre-colonial times to the modern era. It describes how the region was originally settled by indigenous groups like the Subanon people and later saw influxes of other ethnic groups. The Spanish established Zamboanga as a colonial outpost in 1569. In 1899, rebels declared the independent Republic of Zamboanga but it was short-lived and surrendered to American forces in 1899. Zamboanga then served as the capital of the Moro Province under U.S. rule until 1920. It became a chartered city in 1936 and continued developing as a major urban and commercial center of Mindanao through the 20th century.
