On October 4, 1824, Mexico ratified its first-ever constitution as an independent country, a document known as the “Federal Constitution of the United Mexican States.” Ever since that day, the country’s official name has not been Mexico, but rather, the United Mexican States. Like North or South Korea—The Democratic People’s Republic of Korean, or the Republic of Korea, respectively—Mexico almost never goes by its full and proper name. CNN:
he reality is the official name is used only by Mexican officials who deal with diplomatic protocol and official documents pertaining to international relations. For the rest of Mexicans — and the world — the country is simply known as Mexico.
Apparently sick of living a double life, the Mexican (United Mexican Statesian?) President Felipe Calderon, “sent to the Mexican Congress a piece of legislation to change the country’s name officially to simply Mexico.”
President Calderon, however, is in the last leg of his term—the new President, Enrique Peña Nieto, takes over in a week. With time dwindling, says CNN, it’s not clear if Calderon’s re-naming proposal will go through.
