The Amphictyony of Delphi was an ancient Greek religious association of tribes that came together to protect and manage the sacred site of Delphi. This group was responsible for overseeing the Delphic Oracle, a significant religious institution where people sought guidance from the god Apollo. Members of the amphictyony participated in meetings to discuss matters related to the sanctuary and its festivals, such as the Pythian Games. The organization also played a role in maintaining peace among its member tribes, promoting cooperation and mutual support in times of conflict.
