George IV. had, as you know, no child living at the time of his death. His next brother, Frederick Duke of York, died before him, likewise without children, so the crown went to William, Duke of Clarence, third son of George III. He had been a sailor in his younger days, but was an elderly man when he came to the throne. He was a dull and not a very wise man, but good-natured and kind, and had an open, friendly, sailor manner; and his wife, Queen Adelaide, of Saxe- Meiningen, was an excellent woman, whom everyone respected. They never had any children but two daughters who died in infancy: and everyone knew that the next heir must be the Princess Victoria, daughter to the next brother, Edward, Duke of Kent, who had died the year after she was born. King William IV. had always been friendly with the Whigs, who wanted power for the people. Those who went furthest among them were called Radicals, because they wanted a radical reform--that is, going to the root. In fact, it was time to alter the way of sending members to the House of Commons, for some of the towns that had once been big enough to choose one were now deserted and grown very small, while on the other hand, others which used to be little villages, like Birmingham and Brighton, had now become very large, and full of people. The Duke of Wellington and his friends wanted to consider the best way of setting these things to rights, but the Radicals wanted to do much more and much faster than he was willing to grant. The poor fancied that the new rights proposed would make them better off all at once, and that every man would get a fat pig in his sty and as much bread as he wanted; and they were so angry at any delay, that they went about in bands burning the hay-ricks and stacks of corn, to frighten their landlords. And the Duke of Wellington's great deeds were forgotten in the anger of the mob, who gathered round him, ready to abuse and pelt him as he rode along; and yet, as they saw his quiet, calm way of going on, taking no heed to them, and quite fearless, no one raised a hand. They broke the windows of his house in London, though, and he had iron blinds put up to protect them. He went out of office, and the Whigs came in, and then the Act of Parliament was passed which was called the Reform bill--because it set to rights what had gone wrong as to which towns should have members of their own, and, besides, allowed everyone in a borough town, who rented a house at ten pounds a year, to vote for the member of Parliament. A borough is a town that has a member of Parliament, and a city is one that is large enough to have a mayor and an alderman to manage its affairs at home.
