What is the difference between treason and sedition?
Treason is the crime of betraying one's own country, especially by aiding its enemies or trying to overthrow its government, while sedition refers to inciting rebellion or resistance against authority without necessarily reaching the level of betrayal treason implies. Treason is generally considered the more severe charge because it involves active betrayal rather than mere incitement.
What is the difference between treason and espionage?
Treason specifically requires betraying one's own country, often by a citizen owing allegiance to it, whereas espionage refers more broadly to spying or secretly gathering information, which can be committed by anyone regardless of nationality. Espionage can be one method by which treason is carried out, but the two terms are not interchangeable.
