Items Q249748 to Q250919 widen that list with an interesting overlap of 111 names with the members of the Strict Observance. It was the largest and most widespread Freemasonic umbrella organization in Europe, that imploded with a massive impact on the world of Freemasonry in 1782, the same year when the Illuminati began their three years of rapid growth before they imploded in turn from 1786-87 and ceased to exist altogether by August 1788.
The Strict Observance had, in hindsight a longer life, beginning in either 1751 or 1764, depending on how we define their beginning. In a way the Order has not disappeared altogether. It lives on in an augmented form within Sweden’s branch of national Freemasonry, the Swedish Rite. Swedish Masons affiliated with the Strict Observance only in 1778 at the convention of Wolfenbüttel with the election of Duke Carl of Södermanland (later King Carl XIII of Sweden) as Grandmaster, after the death of their founder Baron von Hund in 1776. The Swedish Masons then withdrew in 1780 and created their own IXth Province of the Order, having constructed their own distinct form of Freemasonry on top of the superstructure of the Strict Observance rituals.
