In modern political history the expression "cave of Adullam" (hence "Adullamites") came into common use (being first employed in a speech by John Bright on the 13th of March 1866) with regard to the independent attitude of Robert Lowe (Lord Sherbrooke), Edward Horsman and their Liberal supporters in opposition to the Reform Bill of 1866.
Russell's fourth Reform Bill was introduced, was defeated by the Adullamites, and the Derby-Disraeli ministry was installed.
The bill did not create much enthusiasm among Liberals, and it was naturally opposed by the Conservatives, who were reinforced by a large section of moderate Liberals, nicknamed, in consequence of a phrase in one Of Brights speeches, Adullamites.
