United Republic of North America (Earth-2124)

The United Republic of North America (URNA), more commonly known as the United America or America, is a regional political union on North America, on Earth, being an association of three former states: Canada, Mexico and the remnants of the United States of America.

History
By 2541, Mexico City became the second most populous city in URNA, after New York City.

The Battle of Cleveland, one of the final battles of the First Contact War, was fought on URNA, with millions of civilians attempting to escape the massacre in boats that headed towards Ontario. The UNSC established a military base in Akron in order to plan strategies against the Covenant. After the Prophet of Truth went to the Ark via the Portal of Voi, the Covenant forces on Cleveland soon followed, leaving a sizable jiralhanae team to Arizona in order to locate possible forerunner artifacts, but they were stopped by SPARTAN-II Blue Team.

In July 24th, 2560, New Phoenix was destroyed by the forerunner Didact with the ancient device known as the Composer, killing more than 7 million people and extracting their mental patterns. John-117 was able to stop the Didact from causing even more harm with a HAVOK nuke, which destroyed the Composer and the Didact's ship, the Mantle's Approach.
