A political volte face is always likely to compel attention, especially when performed by a leading politician who thereby seems to reverse his lifelong attitude. So it was in the case of Lord John Russell's hostility to the restoration of the Roman Catholic hierarchy in England and Wales and his adoption of legislation against it. His actions brought him no profit but rather helped to weaken his position. For the Ecclesiastical Titles bill, while it may have been intended as a hopeful introduction to a firmer political existence, appears instead as the culmination of a long decline. Russell never succeeded in recapturing the fulfilment of the years 1828–32, when he played a central part in carrying great constitutional changes which vindicated his principles of religious and civil liberty. After this he witnessed the great reforms being carried by others; as his latest biographer states, ‘Peel had run off with the credit for the free trade policy, Palmerston for the conduct of foreign affairs, Disraeli for the second Reform Act, and Gladstone for the policy of justice to Ireland…’. Moreover, he removed some of the glory of his liberal attainments by writing the Durham Letter and adopting the Ecclesiastical Titles bill—though Russell disagreed with such an opinion, since he denied that it was illiberal to resist ‘papal aggression’. Behaviour so intriguing as Russell's in 1850–1 has naturally been the subject of a good deal of inquiry and comment, but further examination may help to show the comparative importance of factors which contributed to the Prime Minister's motives.
