The Industrial Revolution saw a shift from an economy based on farming and handicrafts to one based on manufacturing in factories. Before industrialization, much work was done in people's homes as part of the cottage industry. The Industrial Revolution began in Britain in the 1750s and spread to other parts of the world at different speeds through industrialization and mechanization. While industrialization increased production and living standards for some, it also led to poor working conditions, urbanization, and negative environmental and health impacts that sparked reforms and ideological debates over economic and political systems.
