Disraeli in 1873Although a major figure in the protectionist wing of the Conservative Party after 1844, Disraeli's relations with the other leading figures in the party, particularly Lord Derby, the overall leader, were often strained. Not until the 1860s would Derby and Disraeli be on easy terms, and the latter's succession of the former assured. From 1852 onwards, Disraeli's career would also be marked by his often intense rivalry with William Gladstone, who eventually rose to become leader of the Liberal Party. In this feud, Disraeli was aided by his warm friendship with Queen Victoria, who came to detest Gladstone during the latter's first premiership in the 1870s. In 1876 Disraeli was raised to the peerage as the Earl of Beaconsfield, capping nearly four decades in the House of Commons.
Before and during his political career, Disraeli was well-known as a literary and social figure, although his novels are not generally regarded as a part of the Victorian literary canon. He mainly wrote romances, of which Sybil and Vivian Grey are perhaps the best-known today. He is exceptional among British Prime Ministers for having gained equal social and political renown. He was twice successful as the Glasgow University Conservative Association's candidate for Rector of the University, holding the post for two full terms between 1871 and 1877.
Disraeli's biographers believe he was descended from Italian Sephardic Jews. He is related to the Italian-British family Rietti. He was baptized by his Jewish father when his father received a fine from the local Synagogue. He claimed Spanish ancestry, possibly referring to the ultimate origin of his family heritage in Spain prior to the expulsion of Jews in 1492, after which many Jews emigrated temporarily to northern Italy before moving to the Netherlands and then England.[5] He was the second child and eldest son of Isaac D'Israeli, a literary critic and historian, and Maria Basevi. Benjamin changed the spelling in the 1820s by dropping the apostrophe.[6] His siblings included Sarah (1802–1859), Naphtali (1807), Ralph (1809–1898), and James (1813–1868).[7] Benjamin at first attended a small school, the Reverend John Potticary's school at Blackheath.[8] His father had Benjamin baptised in 1817 following a dispute with their synagogue. The elder D'Israeli was content to remain outside organized religion. From 1817, Benjamin attended Higham Hall, in Walthamstow. His younger brothers, in contrast, attended the superior Winchester College.
