The correct answer is:
Industrial Revolution.
Before the Industrial Revolution, which started in Britain in the last years of the 18th century, manufacturing was usually performed in people’s homes, ordinarily using hand tools. Industrialization signified a turn to powered, special-purpose machinery, factories, and mass production.
For example, textile making used to be a cottage business that used mostly flax and wool in a handloom. Industrial Revolution moved the cloth production away from the cottage and into manufactories. By the 1820s, all cotton, and wool were produced in mills.
