The definition of Imperialism according to google is a policy of extending a country's power and influence through diplomacy or military force. But a more thorough definition is this: Imperialism is the domination by one country of the political, economic, or cultural life of another country or region. - it's more than just military or government. The reason I wanted to clarify that is because old and new imperialisms happened in an attempt to dominate economically. Old imperialism happened in 1500s to early 1800s. Under Old Imperialism, European powers would build a series of trading stations in their attempt at accumulating wealth.
The original meaning of imperialism was a simple one: imperial government, that is, empire in the classical sense (such as existed in ancient Rome, China, and Greece). In more recent times, imperialism has become synonymous with western hegemony in Africa and Asia from the 18th through the 20th centuries and with the spreading cultural influence of the United States.
