The Pontifical Order of Knights Bachelor of Yugoslavia is a religious association serving as a successor to the Royal Association of Knights Bachelor of Yugoslavia founded by H.M. Peter II, the last reigning King of Yugoslavia. The order was founded under the protection and authority of the Pontifical Imperial State of Rome-Ruthenia, United Roman-Ruthenian Church. It counts among its foundational legacy a nobleman who is a Knight Bachelor of Yugoslavia and knew King Peter II. Coupled with the Stephenian Archives, it maintains rare records of Peter II and the honour of Yugoslavian Knight Bachelor.
