Blake's poem "London" describes the miserable conditions he observed in the city of London during the Industrial Revolution. Through the use of vivid imagery and rhetorical devices, he depicts a place defined by suffering, where poverty, child labor, and disease run rampant. Blake held those in power, like the church and wealthy landowners, responsible for failing to help the lower classes and end their endless cycle of misery. The poem expresses Blake's Romantic and political beliefs opposing the changes brought about by industrialization.
