Northwest Commonwealth

The  was one of the thirteen commonwealths of the pre-war United States of America. Created in the early 21st century, it was comprised of the former states of Northern California, Washington, Oregon, Idaho and Alaska.

History
Alaska was one of the major sites of fighting during the war with China, notably around the Anchorage Front Line. It was very important during the War because of the Trans Alaska pipeline.

War in Alaska
In 2059, the United States establishes a significant military presence to protect its oil interests in Alaska, in light of the ever dwindling oil reserves in the world, as well as increasing tensions with China. In the winter of 2066, the Americans' fears become reality as the Chinese military invades Alaska and takes over a significant portion of the land. Alaska becomes a warzone between the United States and China, furthering fears of nuclear apocalypse around the world. On January 11, 2077, the United States finally reclaims Alaska from the Chinese. Relations between the two were still tense, ultimately leading to the The Great War on October 23rd of the same year.
