Rhymes with TREASON


noun    (Concise Encyclopedia)

Offense of attempting to overthrow the government of one's country or of assisting its enemies in war. In the U.S., the framers of the Constitution defined treason narrowly—as the levying of war against the U.S. or the giving of aid and comfort to its enemies—in order to lessen the possibility that those in power might falsely or loosely charge their political opponents with treason. See also sedition.
