The United Mexican States commonly known as Mexico, was a federal constitutional republic in North America. It is bordered on the north by the United States; on the south and west by the Pacific Ocean; on the southeast by Guatemala, Belize, and the Caribbean Sea; and on the east by the Gulf of Mexico. Covering almost 2 million square kilometres (over 760,000 sq mi), Mexico is the fifth-largest country in the Americas by total area and the 14th largest independent nation in the world. With an estimated population of 111 million, it is the 11th most populous country and the most populous Hispanophone country on Earth. Mexico is a federation comprising thirty-one states and a Federal District, the capital city.
In the Stand Alone Complex series, Mexico and every other nation in Latin America collapsed following the Third World War, becoming extremely corrupt. To augment its political position, the American Empire called for the deployment of United Nations troops in Mexico and other countries to overthrow their corrupt governments.
