William Blake's poem "The Chimney Sweeper" depicts the tragic life of young boys in 18th century England who were forced into child labor as chimney sweeps. The poem tells the story of a young boy, Tom Dacre, who has his head shaved in order to fit into chimneys to clean. Tom dreams of being freed from his life of misery and rising into the sky. The poem highlights the injustice and lack of innocence faced by chimney sweep boys, whose short lives consisted of difficult, dangerous work.
