born March 7, 1842, London, Eng.
died Nov. 22, 1921, London
British Marxist political leader.
Educated at the University of Cambridge, he worked as a journalist before founding the socialist Democratic Federation, and in England for All (1881), the first English socialist book in almost 50 years, he expounded the ideas of Karl Marx . He steered many British socialists toward Marxism, but Friedrich Engels , who disliked Hyndman, encouraged many to break away and form the Socialist League. During World War I Hyndman took a patriotic and pro-French line, causing his ouster from the Socialist Party, whereupon he formed the National Socialist Party (1916), later renamed the Social Democratic Federation.
