The Industrial Revolution was a period of rapid industrial growth and technological advancement that began in the late 18th century and lasted into the 19th century, fundamentally transforming economies from agrarian to industrial. This era saw the rise of factories, mechanized production, and innovations such as the steam engine, significantly altering social structures, labor systems, and cultural norms, paving the way for movements like Neoclassicism and Romanticism that reacted to these changes.
