Five Ideas that shaped the World: Nationalism, Industrialism, Colonialism, Imperialism and communism

Nationalism is a political philosophy holding that the welfare of the nation-state is paramount, and attitude often strengthened when people share a common history, religion, language, or ethnic background.

Industrialism is an economic and social system based on the development of large-scale industries and marked by the production of large quantities of inexpensive manufactured goods and the concentration of employment in urban factories.

Also they started controlling the water for better irrigation and using tools for faster harvesting. These changes had to occur to produce enough food for the people freed from farming going to the factories. Power is the next step that pushed the revolution into the next century. The full industrial revolution developed from steam power and has gone through electric and oil power to the fateful nuclear power of our own day. With all this
