The York Rite is one of the appendant bodies of Freemasonry that a Master Mason may join to further his knowledge of Freemasonry. But the York Rite is not found as a single system worldwide, and outside of the United States there are often significant differences in ritual, as well as organization. However, in most cases, provided that the Grand Body in question regards the parent "Craft" jurisdiction as regular, each distinct Order has recognised fraternal inter-relations with the respective Grand Body within the York system.
