Disraeli was born in Bloomsbury, then a part of Middlesex. His father left Judaism after a dispute at his synagogue; young Benjamin became an Anglican at the age of 12. After several unsuccessful attempts, Disraeli entered the House of Commons in 1837. In 1846 the prime minister at the time, Sir Robert Peel, split the party over his proposal to repeal the Corn Laws, which involved ending the tariff on imported grain. Disraeli clashed with Peel in the House of Commons. Disraeli became a major figure in the party. When Lord Derby, the party leader, thrice formed governments in the 1850s and 1860s, Disraeli served as Chancellor of the Exchequer and Leader of the House of Commons.
