Imperialism occurs when a strong nation takes over a weaker nation or region and dominates its economic, political, or cultural life.
A particularly pernicious example of intra-European imperialism was the Nazi aggression during World War II, which gave the German business cartels and the Nazi state an opportunity to plunder the resources and exploit the labor of occupied Europe, including the slave labor of concentration camps.
The earliest victims of Western European imperialism were other Europeans. Some 800 years ago, Ireland became the first colony of what later became known as the British empire. A part of Ireland still remains under British occupation. Other early Caucasian victims included the Eastern Europeans. The people Charlemagne worked to death in his mines in the early part of the ninth century were Slavs. So frequent and prolonged was the enslavement of Eastern Europeans that "Slav" became synonymous with servitude. Indeed, the word "slave" derives from "Slav." Eastern Europe was an early source of capital accumulation, having become wholly dependent upon Western manufactures by the seventeenth century.
The preponderant thrust of the European, North American, and Japanese imperial powers has been directed against Africa, Asia, and Latin America. By the nineteenth century, they saw the Third World as not only a source of raw materials and slaves but a market for manufactured goods. By the twentieth century, the industrial nations were exporting not only goods but capital, in the form of machinery, technology, investments, and loans. To say that we have entered the stage of capital export and investment is not to imply that the plunder of natural resources has ceased. If anything, the despoliation has accelerated.
Of the various notions about imperialism circulating today in the United States, the dominant view is that it does not exist. Imperialism is not recognized as a legitimate concept, certainly not in regard to the United States. One may speak of "Soviet imperialism" or "nineteenth-century British imperialism" but not of U.S. imperialism. A graduate student in political science at most universities in this country would not be granted the opportunity to research U.S. imperialism, on the grounds that such an undertaking would not be scholarly. While many people throughout the world charge the United States with being an imperialist power, in this country persons who talk of U.S. imperialism are usually judged to be mouthing ideological blather.
