The Ashcan School emerged in early 20th century New York City, challenging idealized art with gritty urban realism. Artists like Robert Henri and George Bellows depicted working-class life, using bold brushstrokes and dark palettes to capture the energy of the city. This movement coincided with the Progressive Era, reflecting social changes and urbanization. The Ashcan artists focused on everyday scenes, exploring themes of poverty, immigration, and social inequality. Their work paved the way for later American realist movements and socially engaged art.
