The National Education League came to prominence in the 1870s as the most militant of the pressure groups that spearheaded the so-called “Nonconformist Revolt” from the Liberal Party. The revolt began in 1870, reached its peak in 1873, and contributed to the Liberal defeat in the general election of 1874. It finally petered out in the wake of that defeat and the emergence of a revitalized liberalism during the Eastern Question agitation in the late 1870s. The National Education League was founded in 1869, and disbanded in 1877, in the midst of the Eastern Question agitation. Because its dates are coincident with the revolt, and because it did play a crucial role in that movement, the league's history has been treated as an integral part of the Nonconformist Revolt. The revolt itself has been generally interpreted as a sectionalist attack on the Liberal Party, launched by Nonconformist grievance organizations for narrow, and largely sectarian, aims. According to this view, the revolt ended when the Nonconformists finally accepted the notion of a comprehensive liberalism that transcended their particularist interests; when they recognized that, politically speaking, they were Liberals before they were Nonconformists.
This explanation is misleading because it ignores the generally radical thrust of the Nonconformist Revolt and the agitations of groups such as the United Kingdon Alliance and the Liberation Society. In particular, the rise and fall of the National Education League cannot be understood solely within the context of Nonconformist politics.
