The Industrial Revolution, which began roughly in the second half of the 1700s and stretched into the early 1800s, was a period of enormous change in Europe and America. The invention of new technologies, from mechanized looms for weaving cloth and the steam-powered locomotive to improvements in iron smelting, transformed what had been largely rural societies of farmers and craftsmen who made goods by hand. Many people moved from the countryside into fast-growing cities, where they worked in factories filled with machinery.
