Sedition is any conduct that tends toward insurrection but does not amount to treason. Sedition is directed against a government, but without an overt act. Sedition includes subversion of a Constitution and incitement of discontent (or of resistance) to lawful authority.
Seditious acts include causing insurrection or disturbances in a state or a revolt against the legitimate authority. Sedition includes any commotion, though not aimed at direct and open violence against the laws.
The difference between sedition and treason consists primarily in the ultimate object of the violation to the public peace. Sedition does not consist of levying war against a government nor of adhering to its enemies, giving enemies aid, and giving enemies comfort.
