Examples from the Web for amphictyony
This later class of festivals agreed with the Amphictyony in being of a special and exclusive character, not open to all Greeks.
Thus there was an Amphictyony of seven cities at the holy island of Caluria, close to the harbor of Troezen.
Sometimes this tendency to religious fraternity took a form called an Amphictyony, different from the common festival.
It did not even prevent members of the Amphictyony fighting one another.History Of Ancient Civilization|Charles Seignobos
