During the early 19th century, the primary industry that developed in the United States was manufacturing, bolstered by the Industrial Revolution. This period saw the rise of factories and mechanization, particularly in textiles and agriculture. The introduction of steam power and advancements in technology allowed for large-scale production and efficiency. The factory system shifted labor practices, moving work from homes and small workshops into centralized facilities. This industrial growth contributed significantly to urbanization, as people migrated to cities for jobs, and laid the groundwork for America’s economic development. It also sparked significant social changes and labor movements that sought better conditions for workers.
