The Industrial Revolution transformed society, economy, and technology from the late 18th to early 20th centuries. Starting in Britain, it spread across Europe and North America, revolutionizing manufacturing, transportation, and communication through innovations like the steam engine and assembly line. This period saw dramatic shifts in work and society. Factories replaced cottage industries, leading to urbanization and the rise of capitalism. New social classes emerged, while workers faced harsh conditions, spurring labor movements and reforms that shaped modern labor laws and unions.
