The Duke of Kent was, as we shall have occasion to show, a strong Whig with philanthropic views. But the ablest of the princes, though also the most unpopular, was the Duke of Cumberland, who, until the birth of the Queen's first child, was heir presumptive to the Throne. He had been one of the most active members of the ultra-Tory party, who had opposed to the last the Emancipation of the Catholics and the Reform Bill. He had married a sister-in-law of the King of Prussia, and lived much in Berlin, where he was intimate with the leaders of the military party, who were the centre of reactionary influences in that country, chief among them being his brother-in-law, Prince Charles of Mecklenburg. In private life the Duke was bluff and soldier-like, of rather a bullying turn, and extraordinarily indifferent to the feelings of others. "Ernest is not a bad fellow," his brother William IV. said of him, "but if anyone has a corn, he will be sure to tread on it." He was very unpopular in England. On the death of William IV. he succeeded to the throne of Hanover, and from that time seldom visited England. His first act on reaching his kingdom was to declare invalid the Constitution which had been granted in 1833 by William IV. His justification for this was that his consent, as heir presumptive, which was necessary for its validity, had not at the time been asked. The act caused great odium to be attached to his name by all Liberals, both English and Continental, and it was disapproved of even by his old Tory associates. None the less he soon won great popularity in his own dominions by his zeal, good-humour, and energy, and in 1840 he came to terms with the Estates. A new Constitution was drawn up which preserved more of the Royal prerogatives than the instrument of 1833. Few German princes suffered so little in the revolution of 1848. The King died in 1851, at the age of eighty, and left one son, George, who had been blind from his boyhood. He was the last King of Hanover, being expelled by the Prussians in 1866. On the failure of the Ducal line of Brunswick, the grandson of Ernest Augustus became heir to their dominions, he and his sons being now the sole male representatives of all the branches of the House of Brunswick, which a few generations ago was one of the most numerous and widely-spread ruling Houses in Germany.[1] [Footnote 1: Of the daughters of George III., Princess Amelia had died in 1810, and the Queen of Würtemberg in 1828; two married daughters survived--Elizabeth, wife of the Landgrave of Hesse-Homburg, and Mary, who had married her cousin, the Duke of Gloucester, and lived in England. There were also two unmarried daughters, the Princesses Augusta and Sophia, living in England.] The Duke of Sussex was in sympathy with many Liberal movements, and supported the removal of religious disabilities, the abolition of the Corn Laws, and Parliamentary Reform.
