The House of Lords was extremely conservative, quite stupid, immensely powerful and a determined enemy of the Liberal Party

By 1910, the Liberals had reached a point where they could no longer advance; before them stood a barrier of Capital which they dared not attack. Behind them stood the House of Lords. In its political aspect, the House of Lords was extremely conservative, quite stupid, immensely powerful and a determined enemy of the Liberal Party.

In 1700 it was a little assembly of great nobles, jealous, stubborn, and perverse; in 1801, through a lavish creation of peerages, it had come to represent the opulent and landed classes. In this way the bribery of George III and the vision of William Pitt had worked to a common end. The Crown was well rid of an obstinate and capricious enemy; the Constitution had gained its first distinctly conservative element. For the Lords never again demonstrated any desire for change. They fought the Whig Reform Bill in 1832; they killed the Liberal Home Rule Bill in 1884.
