One of the most important inventions in the Industrial Revolution for all countries

The Factory System Built close to and powered by water at first Used unskilled labor Bad working conditions/long hours Goal: PROFIT

Overall Changes & Effects Mass production of goods Unskilled labor used Urbanization – growth of cities Movement of people
