Friedrich Engels was the Che Guevara of his day. Like Che, he also came from a privileged background, but rejected middle-class privilege to devote himself to the struggle for the liberation of working people, for justice and socialism. As a young man he fought in the hills of southern Germany with a small band of like-minded guerrillas. After defeat, he fled Prussian persecution to settle in Britain, where he spent the rest of his life. Instead of continuing his adventurous life as a full-time activist, he took on a double life in order to support his friend, Karl Marx. In the middle-class citadels of Manchester, he was known as a staid, honest and respectable businessman, but clandestinely he devoted himself to the struggle fo socialism. His and Marx’s ideas and his vision helped transform the 20th century world and still resonate today. In this fascinating new biography, the icon Engels is given flesh and blood, bringing his life and times vibrantly alive.
