United Kingdom of Hyperborea (Videri Quam Esse)

Early Colonization
After Hyperborea was discovered in 1410 by Scottish Explorer Jonathan Aitcheson, Scotland was the first nation to colonize the area. After landing in "Nova Scotia" (OTL Labrador), their colony grew fast and quick. After receiving news of this, the Brythionic King (OTL London and surrounding areas) sent his own explorers to scout out a location in the area. They landed in OTL New Jersey in 1439, and quickly began exploring the surrounding areas. Once the nations in Spain heard, they all began to colonize different regions of both Hyperborea and Hisperica. Aragon landed in Louisiana, Castile landed in Hispaniola, and Portugal landed in Venezuela, becoming the first explorers of Hisperica. Brythonia bought out the Aragonese colonies of Louisiana and the Castilian colonies of Florida, and began to expand even further to the west.

Renaissance Colonization
Castile united with Aragon under Ferdinand and Isabella, and Hispania began colonizing Mexico. They quickly removed the Aztec peoples in the late 1400's, and colonized up the coast and into OTL Texas.
