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 Age of Imperialism is in most Western terms, defined as the late nineteenth and early twentieth centuries when the US (and Western allies) expanded their economic and political control over other countries. And, in many cases established or continued the rule of colonies. This imperialist group also contained Imperial Japan as a member.
