The modern constitutional militia movement, the constitutionalist wing of the "militia movement" in the United States, became active in the mid 1990s in a response of outrage about the violent confrontation at Ruby Ridge, the Waco Siege and gun control legislation. The movement is composed largely of veterans, libertarians, and Second Amendment advocates who share a common dislike of federal government decisions and actions, and a set of ideals associated with the values of the militia they see embodied in the Constitution.
