3rd Continental Congress -- Shared Members

Provisional Government of the Republic of Texas

The Republic of Texas (RoT) is a group of people who believe that the United States never legally annexed the state of Texas and that Texas is therefore an independent nation. In 1995, the RoT declared the state of Texas to be an independent Republic, and RoT "citizens" have been behaving as if that were the case ever since.  RoT members believe that they are not legally bound to obey the federal government or the state government of Texas, and they resent both for taking away their freedoms.  The RoT is part of the common law movement. (The common law movement declares that its members are exempt from the laws of the United States, and cite pseudo-legal theories that justify their illegal activities, which typically involve issuing phony legal documents such as liens and money orders.)  RoT also teaches its members to practice redemption (a complicated set of bank fraud techniques, morally justified in the eyes of its practitioners by elaborate conspiracy theories) and paper terrorism (using fraudulent legal documents and filings to harass the government).  They do not consider the money orders or comptroller's warrants they issue to be fraudulent, because they believe the United States government has no legal authority to print money, let alone the legal authority to forbid the Republic of Texas from printing its own money.

Resistance, Liberation and Independence Organization (AAA)

Resistance, Liberation and Independence (AAA) operated for a brief period in Greece in 1972.  All five of their claimed attacks were against U.S interests, both military and diplomatic.  Like other Greek terrorist organizations of the era, such as the Revolutionary Organization 17 November (RO-N17), the AAA was opposed to U.S. influence in the region, most likely due to American support for the military junta ruling Greece at the time.  It is unknown whether the AAA was truly an independent terrorist group, or simply an alias of one of the myriad groups operating in Greece in the 1970's.
