Demographics of Zamboanga
The area around Zamboanga has been occupied by indigenous people for approximately 30,000 years.
During the US administration of the Philippines following its acquisition by the United States as a result of the Spanish-American War in 1899, Zamboanga hosted a number of American regional governors, including General John "Black Jack" Pershing (Pershing was Military Commander/Governor of the Moro Province from 1909 to 1914).
Prior to World War II, Zamboanga was the location of Pettit Barracks, where part of the US Army's 43rd Infantry Regiment was stationed. After the successful invasion of the Philippines, the Japanese occupying force landed at Zamboanga on 2 March 1942, and formed a defense headquarters in Zamboanga, which was taken by US forces in 1945.
In 17 October 2002, the Zamboanga bombings occurred, and in 2003, Zamboanga was used as a base for 300 United States military advisors to the Philippines army in their operations against the separatists.
The Philippines government has warned foreigners, including diplomats, to stay away from the city.
