The Industrial Revolution began in Britain in the late 18th century and was driven by technological innovations, new energy sources like steam power, and increases in agricultural productivity. Britain was particularly well-suited for the Industrial Revolution due to its political stability, strong merchant class, accumulation of capital, supply of natural resources like coal and iron, and emphasis on practical science. The Industrial Revolution transformed British society, creating a large middle class and urban working class that faced poor living and working conditions. It subsequently spread across Western Europe and to the United States, profoundly changing social and economic structures globally.
