Marriage of State

A marriage of state is a diplomatic marriage or union arranged between members of different nation-states, or, within a single state, between rival power blocs, historically most common in authoritarian and monarchical societies. The practice dates back to antiquity, appearing as far back as early Grecian culture in the western tradition and to similarly ancient periods in other civilizations. The Greek legend of Helen of Troy is often cited as the best-known classical story of a ruling line surrendering a female member in marriage to secure peace or shore up an alliance between rival states or oligarchies.
