United Republic of North America

The United Republic of North America (abbreviated URNA) is a regional political union on the continent of North America on Earth. It is a loose association between the nations of Canada, Mexico, and the political remnants of the United States.

As the location of the UNSC Defense Force's Supreme Headquarters, the United Republic features many military and other colonial facilities across the continent. This is due largely in part to the historical importance of North America, particularly New York City, to the United Nations.

At least one engagement of the Human-Covenant War, the Battle of Cleveland, was fought in North America; during the battle, many citizens of the metropolitan city attempted to flee north in boats from the invading Covenant forces to Ontario, Canada. While the city suffered minimal damage from hostile and friendly fire, the city's population was significantly decreased by the genocidal Covenant Army.

Speculation
The URNA may be derived from the theoretical North American Union.

Advertisements for Fueder Construction suggest that the national entities of the URNA have somewhat dissolved into a "continent state", as they mention "Salem, Oregon, URNA". In this political entity, all the political subdivisions would likely have been stripped of their duties to their respective nations. The following list details the general political subdivisions that would presumably exist under this system.
 * Canada — Ten provinces and three territories.
 * Mexico — Thirty-one states and one federal district.
 * United States — Fifty states, sixteen territories, and one federal district.
