The New California Republic (NCR) is a democratic federation based in California, but with holdings in Nevada, Oregon, Mexico and along the Colorado River. The Republic is dedicated to old world values such as democracy, liberty and the rule of law, as well as restoring order and progress in the Wasteland, though in recent years, it has faced difficulty living up to those standards.
The New California Republic was born from the remnants of the survivors of Vault 15 and the small walled community they founded known as Shady Sands. Under the leadership of Aradesh, and with the assistance of the Vault Dweller (who saved Tandi, Aradesh's daughter and a future president of the NCR), the community prospered. Trade routes with other settlements allowed cultural exchange, and a movement to form a national entity gradually took root and won popular acceptance. In 2186, the town of Shady Sands changed its name to the "New California Republic" and formed a trial council government to draft a constitution. Four more settlements joined the council, and in 2189 the NCR was voted into existence as a sprawling federation of five provinces: Shady Sands, Los Angeles, Maxson, Hub, and Dayglow.
