The Arizona Party was a political party active at the state and federal level in Arizona from the 1910s, when Arizona was a territory under occupation by the United States, until it was effectively disbanded in the early 1970s. The Arizona Party was a Confederate nationalist organization with connections in the 1920s to the Southern Front and later was roughly divided between supporters of the Progressives and Frontmen starting in the late 1930s. The Arizona Party in its early years was controversially affiliated with the Arizona Brigade of Citizens, or Arizona Hillboys, a violent guerrilla faction that had fought American soldiers during the occupation.
