Before they were Joy Division, the Manchester post-punk band was called Warsaw. They changed their name to avoid confusion with another band called Warsaw Pakt. The name 'Joy Division' was taken from the 1955 novel 'The House of Dolls' by Ka-tzetnik 135633. In the book, the 'Joy Division' referred to groups of Jewish women in Nazi concentration camps who were kept for the sexual pleasure of German soldiers. The band chose the name to reflect the grim, dark themes of their music and the post-industrial desolation of Manchester, rather than as an endorsement of Nazi ideology. Despite the controversy, their debut album 'Unknown Pleasures' became a landmark of the genre. After the tragic suicide of lead singer Ian Curtis in 1980, the remaining members reformed as New Order, moving toward a more electronic, dance-oriented sound.
