Relatively few MPs were Dissenters. However the Dissenters were major voting bloc in many areas, such as East Midlands. They were very well organized and highly motivated and largely won over the Whigs and Liberals to their cause. Gladstone brought the majority of dissenters around to support for Home Rule for Ireland, putting the dissenting Protestants in league with the Irish Roman Catholics in an otherwise unlikely alliance. The dissenters gave significant support to moralistic issues, such as temperance and sabbath enforcement. The nonconformist conscience, as it was called, was repeatedly called upon by Gladstone for support for his moralistic foreign policy. In election after election, Protestant ministers rallied their congregations to the Liberal ticket. In Scotland, the Presbyterians played a similar role to the Nonconformist Methodists, Baptists and other groups in England and Wales The political strength of Dissent faded sharply after 1920 with the secularization of British society in the 20th century. The rise of the Labour Party reduced the Liberal Party strongholds into the nonconformist and remote "Celtic Fringe", where it survived by an emphasis on localism and historic religious identity, thereby neutralizing much of the class pressure on behalf of the Labour movement. Meanwhile, the Anglican church was a bastion of strength for the Conservative Party. On the Irish issue, the Anglicans strongly supported unionism. Increasingly after 1850, the Roman Catholic element in England and Scotland consisted of recent immigrants from Ireland. They voted largely for the Irish Parliamentary Party, until its collapse in 1918.
