The plot which has been already mentioned as one of the unpropitious events that marked the opening of George the Fourth's reign was the famous Cato Street conspiracy. The conspiracy was nothing less than a plot for the assassination, all at once, of the whole of his Majesty's ministers. The principal conspirator was a man named Thistlewood, a compound of half-crazy fanaticism and desperate villany—a creature who believed that he had private vengeance to satisfy, and who had, at the same time, persuaded himself that no good could come to the people of England until an example had been made of the King's official advisers by the avenging hand of the lover of liberty. The novelty as well as the audacity of the plot created a perfect consternation all through England, and it became, for a while, the sincere conviction of a vast number of reasonable Englishmen that the whole political and social system of the kingdom was undermined by such plots, and that only the most strenuous exertions made by the champions of law and order could protect the realm from an outbreak of horrors far transcending any of those that had convulsed France during the worst days of the Revolution. It was soon made clear enough that Thistlewood's plot was a conspiracy which included only a very small number of men, and it has never been quite certain whether it was not originally put in motion by the machination of some of the paid spies and informers whom it was believed, at that time, to be the duty of the Ministry to keep in its service for the detection and the frustration of revolutionary conspiracy. It was the common practice of spies and informers, in those days, to go {16} about secretly in quarters where revolutionary conspiracy was believed to be in existence, to represent themselves to some of the suspected plotters as fellow-revolutionists and brother-conspirators, and thus to get into their confidence, and even to suggest to them some new form of conspiracy, in order that their willingness to accept the suggestion might mark them out as proper subjects for a Government prosecution and obtain for the informers the credit of the detection.
[Sidenote: 1820—Origin of the conspiracy]
Thistlewood had been engaged in popular agitation for some sort of reconstitution of political society, and he had been once put on his trial for some alleged offence arising out of such an agitation. More lucky than many other of his contemporaries under similar conditions, he was brought before a jury who found him not guilty of the charge made against him. Now, if Thistlewood had been a sane member of even an Anarchist organization, he might have been softened in his feelings towards the existing order of things by finding that a jury had actually recognized the possibility of his being formally charged with an offence against the Crown and yet not being guilty. But Thistlewood regarded the bare fact that a charge had been made against him as a crime calling out for vengeance, and in his frenzy he got the idea into his head that Lord Sidmouth, the Home Secretary, was the person on whom he was bound to take revenge. Accordingly, the unfortunate creature actually sent a challenge to Lord Sidmouth, inviting and defying him to mortal combat. Perhaps Lord Sidmouth would have acted wisely if he had taken no notice whatever of this preposterous challenge, but, at the same time, it is only fair to remember that Lord Sidmouth might think it dangerous to the public peace to allow a person to go unrebuked who had sent a challenge to a Minister of the Crown. Criminal proceedings were, therefore, taken against Thistlewood, and, instead of being committed to the protection of a lunatic asylum, the author of the challenge was sentenced to a year's imprisonment. When his prison time was over, Thistlewood came out a man inflamed with a desire for vengeance on all the ruling classes {17} in general, and on Ministers of the Crown in particular. Like the murderer in "Macbeth," he thought himself one whom the vile blows and buffets of the world had so incensed that he was reckless what he did to spite the world. He soon got around him a small gang of agitators as ignorant and almost as crazy as himself, and he initiated them into a grand scheme for dealing a death-blow to all the ministers at once, and then seizing on the Bank, Mansion House, and Tower of London, and from these strongholds proclaiming the existence of a provisional government.
Now the whole notion of such a plot as this, and any possible success coming out of it, may seem, at first sight, too crazy to be accepted by any set of men, however ignorant or however wicked, who were not downright lunatics. But it is certain that Thistlewood did find a small number of men who were not actually lunatics, and who yet were ready to join with him and to risk their lives in his enterprise. The first act in the plot was to be the assassination of the King's ministers. One of the professional spies in the employment of the authorities, a man named Edwards, was already in communication with Thistlewood and his friends. The plot had been for a considerable time in preparation, and it was put off for a while because of the death of George the Third, and the hopes entertained by the conspirators that the new King might go back to the political principles of his earlier years, discard Lord Liverpool, Lord Sidmouth, and his other Tory advisers, and thus render it unnecessary for patriotic men to put them to death in order to save the country.
When, however, it became apparent that George the Fourth was to keep around him the ministers who had served him when he was Prince Regent, it was determined that the work must go on. Edwards, the spy, was able to make it known to Thistlewood that there was to be a dinner of the members of the Cabinet on February 23, 1820, and the opportunity was thought to be placed by a kindly fate in the hands of the conspirators. Meanwhile the minister at whose house the dinner was to take place, Lord {18} Harrowby, was kept fully informed of all that was going on, and he wisely resolved to take no public notice of the scheme until the day for the dinner should arrive, when the instruments of the wholesale murder-plot could be suddenly arrested at the moment of their attempt to carry out their design. Thistlewood and most of his companions had their headquarters in the garrets of a house in Cato Street, Edgware Road, and there it was arranged among them that they should remain until one or two of their accomplices, who were kept at watch for the purpose, should come to them and report that the doomed dinner-guests had assembled. Then the conspirators were to repair to the neighborhood of Lord Harrowby's house in Grosvenor Square. One of the outpost men was to knock at Lord Harrowby's door, and the moment the door was opened all the gang were to rush in and put the ministers to death. Lord Harrowby took good care not to have any guests that evening, but the outpost men of the conspiracy were deceived by the fact that a dinner-party was actually going on at the house of the Archbishop of York next door, and when they saw carriages arriving there they felt sure this was the dinner-party for which they were waiting. They waited there until the last of the guests appeared to have arrived, and then set out to give notice to Thistlewood and his companions. Before the outpost men had got back to Cato Street the police were already there, and an attempt was made to arrest the whole of the conspirators. A scuffle took place, in which Thistlewood stabbed one of the policemen to the heart. The constituted authorities had contrived to make almost as much of a bungle as the conspirators had done; the military force did not arrive in time, and Thistlewood and some of his accomplices succeeded, for the moment, in making their escape. It was only for the moment. Thistlewood was arrested next day. There was nothing heroic or dramatic about the manner of his capture. He had sought refuge at the house of a friend in Moorfields, and he was comfortably asleep in bed when the house was surrounded and he was made prisoner. He was put on trial soon after, and, {19} with four of his accomplices, was sentenced to death, and on May 1 the five were executed.

The evidence at the trial made it clear to any reasonable mind that the plot was confined altogether to the small knot of ignorant desperadoes who held their councils in Cato Street, and to the informer Edwards, who had been in communication with them. The public were never allowed to know what had become of this man Edwards. Had he been pensioned by the Government and been allowed to pass into honorable and comfortable retirement, or was he to be arrested and put on his trial like other conspirators? Several attempts were made to get at the truth by means of questions to the ministers in the House of Commons, but no satisfactory reply could be extracted or extorted. Indeed, it seemed quite probable that the general feeling among the ruling classes at the time would have been that the Government had done a very good thing by employing a man to help in working up murderous conspiracies in order that such conspiracies should be frightened out of existence, and that it was quite right to protect and reward the emissaries who had rendered such faithful service. For a time there was a widespread and sincere belief that the Cato Street conspiracy was only one in a vast network of conspiracies from which nothing but the severest measures of repression could save England. The King himself in his royal message to Parliament was careful to make use of the Cato Street conspiracy as another and a crowning evidence of the necessity which existed for the wholesale application of the criminal law in order to save the State from the triumph of anarchy. A season of absolute panic set in and the most trivial political disturbance arising in any part of the country was magnified into another attempt of the emissaries of revolution to upset the Throne, pull down the Church, and turn the State into the republic of a rabble.
It is quite clear now to all readers of history that such attempts as those planned by the Cato Street conspirators can only exist at a time when stern and savage restrictions are set upon all efforts to obtain a free public hearing for {20} the discussion of political and social grievances. Where political wrongs can be arraigned in the open day, there is no occasion for the work of the midnight conspirator. Already in England public men were coming forward who were filled with the noble and patriotic desire to give the philosophy of history some share in the guidance of political life. Popular education had been totally neglected in England, and, indeed, the too common impression among the ruling classes was that the lower orders of the people could never be kept in due obedience to their superiors if they were permitted to make themselves unfit for their station by learning how to read and write. Even the criminal laws themselves bore terrible testimony to the prevailing ideas, by the fact that property was proclaimed as sacred a possession as life itself.
[Sidenote: 1820—Offences that entailed the death penalty]
In the early days of George the Fourth's reign Sir James Mackintosh, the famous historian, philosopher, and philanthropist, brought into the House of Commons a measure for abolishing the punishment of death in cases of the stealing of property to the value of five shillings, and he succeeded in carrying his measure through Parliament. Up to that time men and women had been executed, year after year, for stealing from a shop any goods of the value of five shillings, were the goods but a few loaves of high-priced bread carried off for the purpose of relieving the sufferings of a hungry family. Sir James Mackintosh's measure aimed at the abolition of the death penalty in a large number of other minor offences, but he only succeeded in robbing the gallows of its victims in two other classes of small offences as well as that which has just been mentioned.
