In 1942, during the [[World War II]], [[President of the Philippines|President]] [[Manuel L. Quezon]] created the [[City of Greater Manila]] as an emergency measure, merging the cities of Manila and Quezon City, along with the municipalities of [[Caloocan]], [[Makati]], [[Mandaluyong]], [[Parañaque]], [[Pasay]], and [[San Juan, Metro Manila|San Juan]].<ref name="eo400">{{cite PH act|chamber=EO|number=400, s. 1942|title=Creating the City of Greater Manila|date=January 1, 1942|accessdate=August 24, 2022|url=https://www.officialgazette.gov.ph/1942/01/01/executive-order-no-400-s-1942/|archive-date=July 1, 2022|archive-url=https://web.archive.org/web/20220701173652/https://www.officialgazette.gov.ph/1942/01/01/executive-order-no-400-s-1942/|url-status=live}}</ref> Furthermore, Manila was divided into the districts of Bagumbuhay, Bagumpanahon, Bagumbayan, and Bagungdiwa, while Quezon City was divided into the districts of Diliman and Balintawak.<ref>{{cite map |author = |title = Map of the City of Manila |trans-title = |map = |map-url = |date = |year = 1942 |url =https://assets.isu.pub/document-structure/210327135441-504a42fce9e9c0dafe948e678988e3b0/v1/68eac8a829832842ad677a95008f9037.jpg |scale = 1:40,000 |series = |publisher = Division of Drafting and Surveys, Office of the City Engineer and Architect, City of Manila |cartography = |page = |pages = |section = |sections = |inset = |edition = |location = |language = |format = |isbn = |id = |access-date =August 24, 2022 |archive-url = |archive-date =}}</ref> [[Jorge B. Vargas]] was appointed as its first mayor. Mayors in the municipalities and heads in the city districts included in the City of Greater Manila served as district chiefs. This was to ensure that Vargas, who was Quezon's principal lieutenant for administrative matters, would have a position of authority recognized under international military law. The City of Greater Manila served as a model for the present-day Metro Manila and the administrative functions of the Governor of Metro Manila that was established during the Marcos administration. 

After World War II, in 1945, President [[Sergio Osmeña]] signed Executive Order No. 58, which dissolved the city of Greater Manila instituted by former President Quezon.<ref name="eo58">{{cite PH act|chamber=EO|number=58, s. 1945|title=Reducing the Territory of the City of Greater Manila|date=July 25, 1945|accessdate=August 24, 2022|url=https://www.officialgazette.gov.ph/1945/07/26/executive-order-no-58-s-1945/|archive-date=March 8, 2023|archive-url=https://web.archive.org/web/20230308195829/https://www.officialgazette.gov.ph/1945/07/26/executive-order-no-58-s-1945/|url-status=live}}</ref>
