Socialism in the United Kingdom
Socialism in the United Kingdom is thought to stretch back to the 19th century, with roots arising in the English Civil War. It has taken many different forms, from the communism of Robert Owen through to the reformist electoral project enshrined in the Labour Party that was founded in 1900 and nationalised a fifth of the British economy in the late 1940s.
