The Northwest Commonwealth was one of the thirteen areas of the pre-War United States. Created in 1969,[1] it was comprised of the former states of Northern California, Washington, Oregon, Idaho and Alaska.

Former AlaskaEdit

Alaska was one of the major sites of fighting during the war with China, notably around the Anchorage Front Line.

War in AlaskaEdit

In 2059, the United States established a significant military force 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 became reality as the Chinese military invaded Alaska and took over a significant portion of the land. Alaska became a war zone between the United States and China, furthering fears of nuclear apocalypse around the world. On January 10, 2077, the United States finally reclaimed Alaska from the Chinese. The war between the two remained intense, ultimately leading to the Great War on October 23rd of the same year.

Brotherhood of SteelEdit

The Brotherhood expanded and stopped through Alaska. They thought it was a great place to settle down, and formed a military network in the area.

Former IdahoEdit

In 2281, the Great Khans could have abandoned the Mojave to try and rebuild their tribe in the wilderness of Idaho.

Former OregonEdit

Little of Oregon is seen in-game, although the southern parts of Oregon appear in Fallout 2. Oregon's cannibals roam around the region, searching for victims to attack. There are a few settlements in the area, those being Klamath and Arroyo.

Former Northern CaliforniaEdit

During the war, San Francisco was evidently hit hard by nuclear weapons. However, humanity has clung to life in and around the bay area.

The Shi have a strong presence around the San Francisco area in 2242, although there are wildly varying claims for their fate beyond that year. The New California Republic may have a foothold in the area, and this is supported by the presence of Sac-Town in 2281.
