Archibald Philip Primrose, 5th Earl of Rosebery, succeeded his grandfather as earl at the age of 21. A Liberal albeit with imperialist views often at odds with prime minister Gladstone, he held the posts of undersecretary for home affairs, lord privy seal, and foreign secretary. Upon Gladstone's retirement in 1894, Queen Victoria personally called on Rosebery to become prime minister, which however occasioned a party crisis resulting in his resignation just one year later to lead a more imperialist division of the Liberal Party. He retired from politics in 1905. His historical monographs include William Pitt (1891) and Napoleon: The Last Phase (1900). He died in 1929.
