Hilaire Belloc was an Anglo-French writer and historian. He was one of the most prolific writers in England during the early twentieth century. He was known as a writer, orator, poet, sailor, satirist, man of letters, soldier and political activist. His Catholic faith had a strong impact on his works. He was President of the Oxford Union and later MP for Salford from 1906 to 1910. He was a noted disputant, with a number of long-running feuds, but also widely regarded as a humane and sympathetic man. Belloc became a naturalised British subject in 1902, while retaining his French citizenship. Belloc wrote on myriad subjects, from warfare to poetry to the many current topics of his day. He has been called one of the Big Four of Edwardian Letters, along with H.G.Wells, George Bernard Shaw, and G. K. Chesterton, all of whom debated with each other into the 1930s.
