Benjamin Disraeli had a successful political career in Britain, serving twice as Prime Minister from 1868 to 1880. He rose from an early opposition to Prime Minister Robert Peel in the 1840s to holding the highest office. As Prime Minister, he implemented several reforms related to workers' rights, education, and British territories abroad. Disraeli developed a philosophy of "One Nation" Toryism and wrote novels that explored political and social issues of the time. He left a significant mark on the Conservative Party by establishing it as a national party focused on rhetoric rather than strict opposition to the Whigs.
