Industrialization is the process of a society shifting from making things by hand to making them with machines in factories. Before industrialization, a shoemaker might spend days crafting a single pair of boots in a small workshop. After industrialization, a shoe factory with dozens of workers and specialized machines could produce hundreds of pairs in the same time.

This transformation began in Britain in the late 1700s and spread across the world over the next two centuries. The invention of powerful machines like the steam engine, the spinning jenny, and the power loom allowed people to manufacture goods faster and cheaper than ever before. Small workshops gave way to large factories. Farmers moved to cities to work in these new industries.

Industrialization changed almost everything about how people lived. Cities grew rapidly as workers flocked to factory jobs. New technologies like railroads and telegraphs connected distant places. Products that were once expensive luxuries, like cloth or tools, became affordable for ordinary families. The process created immense wealth and raised living standards, but it also brought challenges: crowded cities, pollution, difficult working conditions, and the loss of traditional ways of life.

When a country industrializes, it fundamentally transforms its economy and society. Japan industrialized rapidly in the late 1800s. China industrialized in the late 1900s. Today, when we talk about industrialized nations, we mean countries whose economies are built around manufacturing and advanced technology rather than agriculture.
