"Manslaughter" as a general term for homicide was in use in medieval England by the late 1200s, during which time a distinction was forming between homicide committed in necessary self-defence (pardoned without culpability) and homicide committed by accident (pardoned but with moral blame). From 1390, homicide in necessary self-defence or by misadventure became "pardons of course", meaning that the Chancery would issue them by default. Homicide in necessary self-defence would later be acquitted, rather than pardoned. The use of "manslaughter" to cover homicides other than murder emerged by 1547, in a statute. Edward Coke confirms this distinction in "The Third Part of the Institutes of the Laws of England," which remains "the authoritative starting point for any examination of the law of homicide" in the United Kingdom and other common law countries"."
