During the 19th century, London grew enormously as a center of trade and industry. Thousands migrated to the city seeking work, but found terrible conditions in the factories. Children often had dangerous jobs, and workers lived in poverty with low wages and poor housing. The poor were helped by workhouses, but they provided little beyond basic shelter and food. Some Victorian reforms aimed to help the poor, like orphanages and the Salvation Army, but poverty remained a major problem.
