One of the great British politicians of the nineteenth century, Disraeli served twice as Tory Prime Minister (1868 and 1874 - 1880) and was also a prominent figure in opposition. He is most famous today for the bitter hatred between himself and his political rival William Gladstone. He enjoyed the favour of Queen Victoria, who shared his dislike of Gladstone. His most significant political achievements are the 1867 Reform Act, in which he was instrumental, and the creation of the modern Conservative Party, with which he is credited. His literary career was greatly overshadowed by his parliamentary ambitions ('climbing the greasy pole'), but includes both romances and political novels.
