who came up with the idea of imperialism
Imperialism The word imperialism originated from the Latin word imperium,[2] which means supreme power. It first became common with its current sense in Great Britain, during the 1870s and was used with a negative connotation.[3] Previously the word imperialism had been used to describe to what was perceived as Napoleon III's attempts of obtaining political support through foreign military interventions.[3] The term was and is mainly applied to Western (and Japanese) political and economic dominance, especially in Asia and Africa, in the 19th and 20th centuries. Its precise meaning continues to be debated by scholars. Some writers, such as Edward Said, use the term more broadly to describe any system of domination and subordination organised with an imperial center and a periphery.[4] This definition encompasses both nominal empires and neocolonialism.
