The Industrial Revolution was a period from the late 18th to early 19th century where major changes in agriculture, manufacturing, mining, transport, and technology had a profound effect on socioeconomic and cultural conditions. New inventions like the steam engine allowed factories to mechanize production, while new processes like Bessemer steel made goods cheaper. This transition shifted economies from agriculture to industry and led to the rise of new social classes. The Industrial Revolution began in Britain and spread throughout Europe and North America.
