1. The industrial revolution started in England around 1750 and soon factory production spread to France, Holland, Germany, Spain, Russia, etc. Countries like England and Germany which had large reserves of coal and other minerals took lead in developing new industries. –
2. However, as times changed, European countries began to use less and less of their own mineral resources and relied on imports from other countries.
3. The old mining towns and old factories were closed down and new factories grew in new areas.
4. Industrialization also enabled the European countries to import agricultural goods from other countries.
5. Thus they relied less on the agriculture of their countries for their food requirements and raw material requirements.
6. Hence Europe became dependent upon trade with other countries.
7. Initially, this trade was with their colonies in Asia, Africa, and America.
8. However as the colonies became independent, they had to develop new ways of trading with them.
