The Peerage of England constitutes the senior-most stratum of the British nobility, representing those titles of honor created by the English Crown between the Norman Conquest of 1066 and the formal union with Scotland in 1707. Structurally, it is organized into five distinct grades of dignity—Duke, Marquess, Earl, Viscount, and Baron—each conveying specific ceremonial rights, heraldic privileges, and, historically, a writ of summons to sit in the House of Lords. Distinct from the continental nobility, English peerage is governed by the principle of primogeniture, where only the head of the family holds the legal status of a peer, while siblings and children remain legally commoners.
From a heraldic perspective, peers of England are entitled to specific coronets of rank, supporters for their achievement of arms, and the use of the peer's robes in parliamentary and coronation ceremonies. The evolution of this system reflects the transition from feudal tenure, where nobility was tied to land ownership and knight-service, to a peerage 'by patent,' where the dignity is a personal honor conferred by the sovereign. Although the Peerage of Great Britain and the Peerage of the United Kingdom later succeeded it, holders of an English peerage retain precedence over equivalent ranks in subsequent peerages.
