Benjamin Disraeli

Having led the revolt against Peel, Disraeli rebuilt the Conservatives as a party that could win urban working-class votes. He passed the 1867 Reform Act, which roughly doubled the electorate, set up Conservative Central Office and the National Union of local associations, and in his 1874 government passed laws on public health, artisans' housing and trade unions' right to picket peacefully. The 'One Nation' label came later, but the electoral coalition he aimed for became the party's basis for a century.
