There are several theories as to the origin of the Scottish Rite, but as it evolved in France in dates from about 1754 when a Chapter (or College) of Claremont was founded in Paris with seven degrees. By 1758 the system had become a Rite of twenty-five degrees known as the Rite of Perfection, whose Grand Regulations were issued in 1762.
In 1761 Stephen Morin was designated to introduce the Rite into the New World. He first established the Rite in Kingston, Jamaica and in San Domingo. On the mainland, Bodies were set up at New Orleans, LA in 1763, at Albany, NY in 1767, at Philadelphia, PA in 1782, and at Charleston, SC in 1783.
In 1786 "Grand Constitutions" were enacted in an attempt to bring order out of the chaotic condition of the degrees in Europe. It was these Constitutions which brought "The Ancient and Accepted Scottish Rite" into formal existence, enlarging the number of degrees to thirty-three, with the 33rd degree as a governing Supreme Council.
The Grand Constitutions of 1786 were issued in the name of Frederick the Great of Prussia as titular head of the Rite, but, he was suffering from terminal illness at the date they were promulgated, and died soon afterwards.
No degree of the Scottish Rite seems to have had its actual origin in Scotland. The term "Scottish" is translation of the French "Ecossais" in the French titles of some of the degrees of the Rite of Perfection. There may well be a traditional connection here. One or two of the degrees were long supposed to have been devised by the Chevalier Andrew Michael Ramsay, a learned Scotsman, tutor to Prince Charles Edward, the Young Pretender. These degrees seem to have afforded a meeting place for those in exile in France, who were adherents of the Stuarts and who were plotting for the restoration of James II and his son to the throne of England.
In 1801 a Supreme Council was opened in Charleston, SC under the above constitutions, absorbing the previously existing Rite of Perfection. This Supreme Council subsequently issued warrants for other Supreme Councils. All other regular Supreme Councils of today are descended, directly or indirectly, from this the Supreme Council of the Southern Jurisdiction, United States of America.
In 1813 the Southern Jurisdiction established the Supreme Council 33° for the Northern Masonic Jurisdiction of the United States. In 1845 the Northern Masonic Jurisdiction warranted a Supreme Council in England and Wales which, in 1874, authorized the formation of the Supreme Council of Canada.
At the time our Supreme Council was chartered, Scottish Rite Bodies were already operative in Hamilton, ON, (1868); London, ON, (1868); St. John, NB, (1868); Halifax, NS, (1870): Toronto, ON, (1873); and Montreal, QC, (1873). Our Supreme Council is in amity with more than 40 other Supreme Councils throughout the world, and 4 National Grand Lodges in the Scandinavian countries.
