Mandaue became independent from being an American Commonwealth and a Japanese garrison on July 4, 1946 along with the entire nation. Mandaue became a chartered city on August 30, 1969 and decades later it was recognized as an HUC (Highly Urbanized City) on February 15, 1991. In early-April 2019, Duterte signed a law that declared Mandaue City as a lone legislative district, which means that it will be separated from the sixth district, and will have its own representative of the lone district.
