Treason
Crime of attacking a state authority to which one owes allegiance.
Treason is the crime of attacking a state authority to which one owes allegiance. It typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying for a hostile foreign power, or attempting to kill its head of state. Historically, in common law countries, treason also covered the murder of specific social superiors, such as a husband by his wife or a master by his servant, with high treason against the monarch distinguished from petty treason against a lesser superior. As petty treason was abolished in various jurisdictions, the term treason came to refer solely to what was once known as high treason.
The word treason itself derives from the Latin *tradere*, meaning "to deliver or hand over," and is linked to the term "traditors," which described Christians who betrayed their fellow believers or surrendered sacred texts during the Diocletianic Persecution. In medieval times, the crime was conceived as a breach of loyalty to the monarch, and most cases involved internal political conflicts, though aiding a foreign sovereign was also considered treasonous. The Treason Act 1351, later called "the pole star of English jurisprudence," was the first statutory definition of the crime. By the Elizabethan era, courts expanded the definition through constructive treason, using it as a tool of political control; for instance, mere speech that "disabled the title" of the monarch could be deemed treasonous, departing from the earlier view that words alone could not constitute treason without an overt act.
The English and French Revolutions introduced a radical shift, placing sovereignty in "The Nation" or "The People," meaning that even a monarch could be accused of treason for failing in their duty of loyalty. Monarchs such as Charles I of England and Louis XVI of France were executed on such charges, though later restorations often reframed their accusers as the true traitors. In modern times, the term is most frequently applied to those who aid an enemy during war. A notable case from the American Revolution involved a slave named Billy, sentenced to death for joining the British against Virginia; he was pardoned after it was argued that, lacking citizenship and its benefits, he owed no allegiance and thus committed no treason—a ground-breaking departure from earlier precedents where slaves were e

Lore & Background
During the 12th century, the rights of the king were gradually set apart from other nobles, and by Edward I's reign the Crown asserted authority to recognize rebellions as treasonous. By the Elizabethan age, courts applied constructive treason as a form of political control, and Edward Coke decided in *R v Owen* that mere speech about the monarch could be treason if it 'disabled his title'. Historically, the crime was conceived as a subject’s failure of loyalty to the sovereign, with queens Anne Boleyn and Catherine Howard executed for adultery against Henry VIII on treason grounds, though evidence in Boleyn’s case is widely regarded as dubious. In Denmark, a man having sexual relations with a queen could be guilty of treason against her husband the king. The English and French Revolutions shifted sovereignty to "The Nation" or "The People," allowing monarchs like Charles I and Louis XVI to be tried and executed for treason against them. After the Restoration, Charles II considered the revolutionaries who sentenced his father as traitors in the traditional sense. In medieval times, most treason cases involved internal kingdom politics, while modern usage focuses on helping an enemy in war. A groundbreaking case during the American Revolution saw a slave named Billy pardoned after arguing he owed no loyalty to Virginia, as he was not a citizen and enjoyed none of its benefits. The term "traitor" derives from Latin *tradere*, "to deliver or hand over," and originally referred to Christians who betrayed fellow believers or sacred scriptures during the Diocletianic Persecution.
Reader's Guide
The concept of treason has evolved significantly over centuries. Originally conceived as a crime against the monarch, the English and French Revolutions introduced the idea that sovereignty resides with 'The Nation' or 'The People', making even monarchs liable for treason. In modern times, 'traitor' and 'treason' are mainly used regarding a person helping an enemy in time of war or conflict. The term has also been used as a political epithet regardless of verifiable treasonable action, as seen in the Dolchstoßlegende (stab-in-the-back myth). Notable cases, such as that of Billy the slave during the American Revolution and William Joyce (Lord Haw-Haw), illustrate debates over allegiance and citizenship.
