Explanation:
With the rapid rise in wealth of the Industrial Revolution, some Europe countries expanded their empires into Asia and Africa.
The desire for expansion was motivated by the promise of economic growth, the sting of national rivalries, and a sense of moral superiority. Europe was looking to strengthen their trade markets throughout the world.
