I want to know the answer to the following question:
Why did English Freemasonry almost come to a halt in 1799?
All the background I'm provided with is that "The Grand Masters of both the Moderns and the Antients Grand Lodges called on Prime Minister William Pitt (who was not a Freemason) and explained to him that Freemasonry was a supporter of the law and lawfully constituted authority and was much involved in charitable work.". Is that enough to answer the question?
