country and continued to send in his reports to the newspaper. He subsequently published his despatches in two works, London to Ladysmith via Pretoria and Ian Hamilton's March (both 1900). He returned to Britain in 1900 and was elected as the Member of parliament for the Oldham constituency at that year's general election. As a serving MP he began publishing pamphlets containing his speeches or answers to key parliamentary questions. Beginning with Mr Winston Churchill on the Education Bill (1902), over 135 such tracts were published over his career. Many of these were subsequently compiled into collections, several of which were edited by his son, Randolph and others of which were edited by Charles Eade, the editor of the Sunday Dispatch. In addition to his parliamentary duties, Churchill wrote a two-volume biography of his father, Lord Randolph Churchill, published in 1906, in which he "presented his father as a tory with increasingly radical sympathies", according to the historian Paul Addison. In the 1923 general election Churchill lost his parliamentary seat and moved to the south of France where he wrote The World Crisis, a six-volume history of the First World War, published between 1923 and 1931. The book was well-received, although the former Prime Minister Arthur Balfour dismissed the work as "Winston's brilliant autobiography, disguised as world history". At the 1924 general election Churchill returned to the Commons. In 1930 he wrote his first autobiography, My Early Life, after which he began his researches for Marlborough: His Life and Times (1933–1938), a four-volume biography of his ancestor, John Churchill, 1st Duke of Marlborough. Before the final volume was published, Churchill wrote a series of biographical profiles for newspapers, which were later collected together and published as Great Contemporaries (1937). In May 1940, eight months after the outbreak of the Second World War, Churchill became Prime Minister. He wrote no histories during his tenure, although several collections of his speeches were published. At the end of the war he was voted out of office at the 1945 election; he returned to writing and, with a research team headed by the historian William Deakin, produced a six-volume history, The Second World War (1948–1953). The books became a best-seller in both the UK and US. Churchill served as Prime Minister for a second time between October 1951 and April 1955 before resigning the premiership; he continued to serve as an MP until 1964.
