Imperialism is the practice, theory or attitude of maintaining or extending power over foreign nations, particularly through expansionism, employing not only hard power (economic and military power), but also soft power (cultural and diplomatic power). Imperialism focuses on establishing or maintaining hegemony and a more or less formal empire.
While related to the concepts of colonialism, imperialism is a distinct concept that can apply to other forms of expansion and many forms of government.
Etymology and usage
The word imperialism originated from the Latin word imperium, which means supreme power, "sovereignty", or simply "rule". The word “imperialism” was originally coined in the 19th century to decry Napoleon’s despotic militarism and became common in the current sense in Great Britain during the 1870s, when it was used with a negative connotation. By the end of the 19th century it was being used to describe the behavior of empires at all times and places. Hann
