Kingdom of Upper Columbia

The Kingdom of Upper Columbia was an independent country in the Pacific Northwest of North America that existed between 1799 and 1862. Founded by an exiled former king of Lower Columbia, it began as an absolute monarchy under the rule of King Michael I and remained so until after his death. His son accepted the people's demands for a constitution and limited government, turning Upper Columbia into a constitutional monarchy.

Upper Columbia remained antagonistic toward Lower Columbia for most of its existence, eventually invading the latter in the war that would cause its downfall. As a result of that war, Upper Columbia was annexed by Lower Columbia in 1862, becoming a federal state of that country, as it remains to this day.

Geography
Upper Columbia was situated between the Federal Republic of Gudland to the west, Lower Columbia to the south, and the British territory of Rupert's Land to the north and east. Its territory was largely mountainous and centered on the Columbia Mountains. Most of the population lived in the valleys between the mountain ranges, along lakes and the upper reaches of the Columbia River, after which the kingdom was named.
