“There was some crossover between QAnon and the sovereign citizen movement before, but I’ve seen sovereign citizen ideas about the United States being a ‘corporation’ become more popular within QAnon and beyond in January,” Travis View, a conspiracy theory researcher, told VICE News.

“It’s concerning because it means QAnon is borrowing ideas from more-established extremism movements.”

Sovereign citizens believe that a law enacted in 1871 secretly turned the U.S. into a corporation and did away with the American government of the founding fathers. The group also believes that President Franklin D. Roosevelt sold U.S. citizens out in 1933 when he ended the gold standard and replaced it by offering citizens as collateral to a group of shadowy foreign investors.

Sovereigns use indecipherable legal filings based on arcane texts to separate themselves from the legal entities the government has supposedly created in their name in order to sell to investors.
