What was "the New Imperialism"?

The New Imperialism was when the Europeans wanted to conquer most part of the world. European Imperialism was applied in the Americas when the Spanish conquered most of south and central America, and when the Portuguese conquered also a part of South America, and England and France conquered North America, they Imperialised this territories, because they controlled the economy, the culture(including their religions) and government of the land. But the Europeans wanted more, and they also wanted to conquer Africa and Asia.

Because of the Industrial Revolution, Europe increased its technology and economy, they also had a big military strenght, they abused from their power and "expanded their empire."
Manufacturers wanted more natural resources to produce their products, and sold therm in markets,they supported an oversea expansion.

Nationalism played a big role, France moved into West Africa, its rival nations Britain and Germany seized lands to halt further French expansion.
As the Europeans wanted more territory for them, they fought each other for land. Like every other events in history, Imperialism also had Positive and Negative effects.

In fact Imperialism was like and still as an Ideology where people wanted to dominate the world because they had better armies, government, economy than the territories that they wanted to conquer.
