The Gordon Riots were the most formidable popular rising of the eighteenth century. In 1778 a Bill, brought forward by Sir George Savile, for the relaxation of some of the harsher penal laws against Catholics, passed almost unanimously through both Houses. Protestant associations were formed in Scotland; a leader was found in Lord George Gordon, a silly young man of twenty-eight years of age, and the agitation spread to England. Mobs collected in London, and interfered with the House of Commons; as they realised their strength, they proceeded to various excesses, destroying Catholic churches and the houses of prominent Romanists. The original objects of the agitation were entirely lost sight of in the disturbances, which were merely the unreasoning ravages of a wild mob. For five days the City was terrorised by the rioters, who were at length dispersed by the military authorities. =Source.=—Boswell's _Life of Johnson_. While Johnson was thus engaged in preparing a delightful literary entertainment for the world, the tranquillity of the metropolis of Great Britain was unexpectedly disturbed by the most horrid series of outrages that ever disgraced a civilised country. A relaxation of some of the severe penal provisions against our fellow subjects of the Catholic communion had been granted by the legislature, with an opposition so inconsiderable, that the genuine mildness of Christianity, united with liberal policy, seemed to have become general in this island. But a dark and malignant spirit of persecution soon showed itself, in an unworthy petition for the repeal of the wise and humane statute. That petition was brought forward by a mob, with the evident purpose of intimidation, and was justly rejected. But the attempt was accompanied and followed by such daring violence as is unexampled in history. Of this extraordinary tumult, Dr. Johnson has given the following concise, lively, and just account in his "Letter to Mrs. Thrale."
