Question: Did the trade affect the Aleut people negatively? Passage:The maritime fur trade brought the Pacific Northwest coast into a vast, new international trade network, centered on the north Pacific Ocean, global in scope, and based on capitalism, but not, for the most part, on colonialism. A triangular trade network emerged linking the Pacific Northwest coast, China, the Hawaiian Islands (only recently discovered by the Western world), Britain, and the United States (especially New England). The trade had a major effect on the indigenous people of the Pacific Northwest coast, especially the Aleut, Sugpiaq, Tlingit, Haida, Nuu-chah-nulth, and Chinook peoples. A rapid increase of wealth occurred among the Northwest Coast natives, along with increased warfare, potlatching, slaving, and depopulation due to epidemic disease. However, the indigenous culture was not overwhelmed by rapid change, but actually flourished. For instance, the importance of totems and traditional nobility crests increased, and the Chinook Jargon, which remains a distinctive aspect of Pacific Northwest culture, was developed during this era. Native Hawaiian society was similarly affected by the sudden influx of Western wealth and technology, as well as epidemic diseases. The trade's effect on China and Europe was minimal, but for New England, the maritime fur trade and the significant profits it made helped revitalize the region, contributing to its transformation from an agrarian to an industrial society. The wealth generated by the maritime fur trade was invested in industrial development, especially textile manufacturing.
