The Commonwealth of Cascadia, more commonly known as Cascadia is a sovereign state in North America. It is bordered by the Californian Republic and Deseret to the south, Canada , Wyoming and the Blackfoot Confederation to the east and the Pacific Ocean to the west. Its capital city is Calgary whilst its largest city is Seattle. 

Early History

The area currently occupied by Cascadia was inhabited by countless indigenous tribes with populations numbering in the hundreds of thousands for millenia until European explorers arrived in the late 15th and early 16th centuries. Early exploration was undertaken by explorers from Spain but explorers from the United Kingdom, then known as Great Britain soon took over and established colonies in the area. The primary British colony in the area was known as "British Columbia", which became associated with the Dominion of Canada on the west coast in the 19th century following the completion of the Canadian Pacific (CP) Railway. Expansion of the United States in the later part of the 19th century led to what is known today as the "Oregon Boundary Dispute", in which disputed expansion plans led to negotiations establising a boundary along the 49th parralel and giving Britain control over Vancouver island, where it remained until the establishment of Cascadia as an independent country.

Modern History

In June of 2009, following the global economic slowdown of the previous year, the Canadian province of Quebec held a referendum in an attempt to gain independence to both assert its own distinct identity and establish firmer control over its own economy. The referendum, the third attempt of its kind was successful and Quebec became an independent republic. The states and provinces of both the United States and Canada were left in shock to see this happen, which led to a number of states becoming independent of the United States including Texas and Deseret. Northern California left California but remained with the Union as a state called Jefferson. In the 2010's, increasing disputes between the west coast governments of Washington, Oregon, Jefferson, British Columbia, Alaska, Alberta, Montana and Idaho led to strengthened regionalism. The first to declare independence were British Columbia and Alberta following a ruling by a Canadian Supreme Court that a series of pipelines from resource-rich Alberta to ports at Kitimat, Prince Rupert and in the Lower Mainland were "unlawful to build". Alberta and British Columbia federated in May of 2013 to form the Pacific Federation, the second blow to what was an already-weakened Canadian federation. Seeing the actions of their neighbours to the north, Washington and Oregon bid within months to join the former Canadian provinces to form the nation-state now known as the Commonwealth of Cascadia. Jefferson and Alaska followed within a year, and by 2015, Cascadia's current borders were established through regional dialogue with locals. The pipelines from Alberta to the Pacific coast were built and a strong economic engine to drive the new country forward was up and running. 

In the present day, large fields of oil have been discovered in the Beaufort Sea and municipalities along the northern coast including Prudhoe Bay, Utqiagvik/Nome and Inuvik have become regional boom towns as staging areas for getting the resource out of the ground.

Government and Politics

Cascadia was established in its early forms as a decentralised Federal Parliamentary Republic, and it retains this form of government to this day. The Parliament of Cascadia is a unicameral assembly consisting of representatives from a number of parties from across the country. The head of state, the President, is mostly a ceremonial role with some direct power for certain situations. This position is held for ten years at a term and can be renewed. The head of government, the Prime Minister is responsible for leading a cabinet, which makes decisions for the various ministries and divisions of the government. In addition, the Prime Minister is a sitting member of the Parliament, along with the members of the cabinet.  Much power is delegated to the governments of the various Provinces of Cascadia, which are responsible for most items that affect the daily lives of citizens, such as education, healthcare and infrastructure. The federal government is primarily responsible for dealing with items on the global stage, such as trade, border security and international relations, among other things.


Detailed Map


Map of Cascadia with cities of regional importance highlighted.

Cascadia is organised as a federation of six provinces that are constitutionally equal to one another.


Flag of Alaska

Flag of Alaska

Alaska is the largest and northernmost province in Cascadia. It consists of the former US State of Alaska (for which it is named), the former Canadian territory of the Yukon and the Northwest Territory west of the Mackenzie River. Its geography is primarily tundra, mountains and forest. With recent global warming trends, small tracts of land have become suitable for agriculture in Alaska. Alaska has vast reserves of primarily ore resources, and as of recent, vast offshore oil reserves.

Most of northern Alaska's wilderness is protected as a Parks Cascadia National Park. The capital city of Alaska is Anchorage.


Flag of Alberta

Flag of Alberta

Alberta is Cascadia's second largest province and consists of the former Canadian Province of Alberta, along with small western parts of the Canadian Province of Saskatchewan, mostly surrounding the city of Lloydminster. It also plays host to the capital city of Cascadia. Alberta's geography is incredibly diverse, ranging from vast boreal forests in the north, to some of the northernmost portions of the North American Great Plains in the south, to the majestic Rocky Mountains in the west. Alberta, with its vast reserves of effectively every type of resource and industry, including natural gas, oil sands, coal and others such as tourism, technology and agriculture leaves it to function as the economic engine of Cascadia.

Flag of Columbia

Columbia is Cascadia's most populous province, with two major cities -Vancouver and Seattle- existing effectively right next door to each other, forming an almost contiguous built-up area. Columbia consists of the southern portion of the former Canadian province of British Columbia (from which the province's name is derived from), along with the former US State of Washington and portions of northern Idaho. Much of Columbia's geography consists of mountainous and hilly forested areas, though there some areas that are suitable for agricultural development, such as the Fraser River's delta, where the Vancouver metropolitan area is located. Columbia plays host to a thriving tourism industry, especially along its coast and on lakes in its interior, such as the Okanogan. There is also a decently sized resource sector in the northern and southern parts of the province.


Montana alternate

Flag of Montana

Montana is Cascadia's smallest province, both by area and population. It primarily consists of the western half of the former US state of Montana, but it also has portions of the former US State of Wyoming. It is geographically divided, with the Rocky Mountains in the west and the Great Plains in the east. Montana has strong mining and agriculture sectors, which has lead to it being known as the "second breadbasket", in its relation to Alberta.

New Caledonia

Flag of New Caledonia

New Caledonia is among the larger of Cascadia's provinces by land area, but it ranks low on the population chart, having only a handful of cities over 10,000 people, and only one over 100,000. New Caledonia consists of the northern portion of the former Canadian province of British Columbia. Its geography is split primarily between vast hilly boreal forests and mountains, both in the east and west. Some isolated areas, primarily in river valleys are suitable for agricultural development however. New Caledonia has a strong tourism sector, having large swaths of untouched wilderness which appeal to trekkers from around the world. It also posesses a vast resource economy, particularly in forestry and natural gas.

Flag of Oregon

Oregon has a vast geography, extending from the coast of the Pacific Ocean, to over 1000km inland in the western portion of the former US State of Wyoming. It consists of the former US States of Oregon, the southern portion of Idaho and the western portion of Wyoming. Oregon's geography is varied, having lush forest along its coast, a rain shadow steppe and numerous mountain ranges. This varied geography has enabled Oregon to have a varied economy, including strong tourism, particularly on the coasts and in the mountains, and a strong agriculture sector (particularly ranching).

Climate Map

Cascadia has a wildly varied climate, ranging from dry, desert-like arid areas to plains to vast boreal forests and lush coastal rainforests. The varied climate of Cascadia has provided immense benefit to the domestic economy, both in the various resource sectors and tourism.


Thanks to the vastness of Cascadia and the sheer variety of natural resources the land provides, Cascadia posesses a strong, diversified economy.
