The movement is rooted in racism and anti-Semitism, though most sovereigns, many of whom are African American, are unaware of their beliefs' origins. In the early 1980s, the sovereign citizens movement mostly attracted white supremacists and anti-Semites, mainly because sovereign theories originated in groups that saw Jews as working behind the scenes to manipulate financial institutions and control the government. Most early sovereigns, and some of those who are still on the scene, believed that being white was a prerequisite to becoming a sovereign citizen. They argued that the 14th Amendment to the Constitution, which guaranteed citizenship to African Americans and everyone else born on U.S. soil, also made black Americans permanently subject to federal and state governments, unlike themselves.

Recruits
In the late 2000s and early 2010s, most new recruits to the sovereign citizens movement are people who have found themselves in a desperate situation, often due to the economy or foreclosures, and are searching for a quick fix. Others are intrigued by the notions of easy money and living a lawless life, free from unpleasant consequences. Many self-identified sovereigns today are black and apparently completely unaware of the racist origins of their ideology. When they experience some small success at using redemption techniques to battle minor traffic offenses or local licensing issues, they're hooked. For many, it's a political issue. They don't like taxes, traffic laws, child support obligations or banking practices, but they are too impatient to try to change what they dislike through traditional, political means.
