Modernizing Illinois, 1870-1917
Following the Civil War Illinois continued to grow in population, diversity, and complexity. Large-scale heavy manufacturing and a growing commercial sector joined agriculture as major employers of a rapidly growing population. Immigration continued, with African Americans from the South and southern and eastern Europeans joining more established groups. Conflicting interests sometimes led to unrest, strikes, and even violence. During this period Illinois also became a center of exciting new movements in art, architecture, and literature.
