Phi Delta Phi

Phi Delta Phi (ΦΔΦ; commonly known as Phid or PDP) is a law-student honor society and professional fraternity founded in 1869 at the University of Michigan.

Phi Delta Phi is organized by two branches: legal honor societies and pre-law societies. The legal honor societies, called Inns, are located at law schools. The pre-law societies, called Halls, are for undergraduate membership at U.S. colleges and universities.

With a total membership of over 200,000 people, members of Phi Delta Phi include five U.S. presidents, two U.S. vice presidents, 14 Supreme Court justices, and numerous members of Congress, Cabinet members, and ambassadors.
