  1. Treason

    In law, treason is the crime that covers some of the more extreme acts against one's sovereign or nation. Historically, treason also covered the murder of specific social superiors, such as the murder of a husband by his wife or that of a master by his servant or slave. Treason against the king was known as high treason and treason against a lesser superior was petty treason. A person who commits treason is known in law as a traitor. Oran's Dictionary of the Law defines treason as "...[a]...citizen's actions to help a foreign government overthrow, make war against, or seriously injure the [parent nation]." In many nations, it is also often considered treason to attempt or conspire to overthrow the government, even if no foreign country is aiding or involved by such an endeavor. Outside legal spheres, the word "traitor" may also be used to describe a person who betrays their own political party, nation, family, friends, ethnic group, team, religion, social class, or other group to which they may belong. Often, such accusations are controversial and disputed, as the person may not identify with the group of which they are a member, or may otherwise disagree with the group members making the charge. See, for example, race traitor, often used by White supremacists and of people in inter-racial relationships.
