The describing phrase 'one-nation Tory' originated with Benjamin Disraeli (1804–1881), who served as the chief Conservative spokesman and became Prime Minister in February 1868. He devised it to appeal to working-class people, who he hoped would see it as a way to improve their lives via factory and health acts as well as greater protection for workers. The ideology featured heavily during Disraeli's terms in government, during which considerable social reforms were passed by the British parliament. Towards the end of the 19th century, the Conservative Party moved away from paternalism in favour of free-market capitalism. In the first half of the 20th century, fears of extremism saw a revival of one-nation conservatism. The Conservative Party continued to espouse the philosophy throughout the post-war consensus from 1945. One-nation thinking influenced their tolerance of the Labour government's Keynesian intervention in the economy, formation of a welfare state and the National Health Service. Thanks to Iain Macleod, Edward Heath and Enoch Powell, special attention after 1950 was paid to one-nation conservatism that promised support for the poorer and working class elements in the Party coalition.
