Industrialization: The First Phase
Most products people in the industrialized nations use today are turned out swiftly by the process of mass production, by people (and sometimes, robots) working on assembly lines using power-driven machines. People of ancient and medieval times had no such products. They had to spend long, tedious hours of hand labor even on simple objects. The energy, or power, they employed in work came almost wholly from their own and animals' muscles. The Industrial Revolution is the name given the movement in which machines changed people's way of life as well as their methods of manufacture.
The most important of the changes that brought about the Industrial Revolution were[:]
- the invention of machines to do the work of hand tools;
- the use of steam, and later of other kinds of power, in place of the muscles of human beings and of animals; and
- the adoption of the factory system.
