"Imperialism resembles Darwinism, in that many use the term but few can say what it really means. This imprecision is encouraged by a surfeit of synonyms. Two stand out: imperialism is taken to be interchangeable with colonialism and reducible to the word "empire." Add to these the compounding effects of elaborations such as hegemony, dependency, or globalization and the definitional space of imperialism becomes a vague, consensual gestalt. In its stricter Marxist-Leninist applications, the word "imperialism" dates from the end of the nineteenth century and minimally connotes the use of state power to secure (or, at least, to attempt to secure) economic monopolies for national companies."
