The Republic of Zamboanga's declared sovereignty lasted from May 18, 1899 until November 16, 1899, wherein its revolutionary government and chosen President, Vicente Álvarez, who led the liberation of the Zamboangueños from the tenuous grip of the retreating Spanish military, along with his victorious troops, exercised de facto sovereignty over administrative functions and military control within their new country territory and was not subordinate or subject to any other government or authority in the Philippines. Álvarez proclaimed his new Republic of Zamboanga had rule over the entire islands of Mindanao, Basilan, and Sulu - effectively the entire southern Philippines. His claim was grandiose. In reality, the republic's sovereignty extended only over the existing premises of ancient Zamboanga, which can be estimated to be about the same size as present-day Zamboanga City is.
In March 1903, Arquiza's government ended and was replaced by a new U.S. governor, also effectively ending the Republic of Zamboanga. Zamboanga is made capital of consolidated Mindanao, Basilan,& Sulu Archipelago, after abolition of the Republic. The Moro Province had 5 districts: Sulu, Zamboanga, Lanao, Cotabato, and Davao.

Pershing, the Legislative Council of the Moro Province passed on September 15, 1911, Act No. 272, converting the municipality of Zamboanga into a city with a commission form of government. Its municipal board consisted of a mayor and two commissioners. On February 26, 1937, the City Charter of Zamboanga became effective and the new city government was inaugurated headed by a mayor appointed by the President of the Philippine Commonwealth. With the passage of Republic Act No. 1210 on April 29, 1955, the position of mayor became elective and the post of vice-mayor was created.
