York Rite of Freemasonry
From Masonic Wiki
The York Rite is one of several Rites of Freemasonry. A Rite is a series of progressive degrees that are conferred by various Masonic organizations or bodies, each of which operates under the control of its own central authority. The York Rite specifically is a collection of separate Masonic Bodies and associated Degrees that would otherwise operate independently. The three primary bodies in the York Rite are the Chapter of Royal Arch Masons, Council of Royal & Select Masters or Council of Cryptic Masons, and the Knights Templar, each of which are governed independently but are all considered to be a part of the York Rite. There are also other organizations that are considered to be directly associated with the York Rite, or require York Rite membership to join such as the York Rite Sovereign College but in general the York Rite is considered to be made up of the aforementioned three. The Rite's name is derived from the city of York, where, according to a Masonic legend, the first meetings of Masons in England took place, although only the lectures of the York Rite Sovereign College make reference to that legend.
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 world wide, and outside of the York Rite 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.
