A country founded by immigrants

The earliest one was Britain, 1607- 1733, whose immigrants successively established Virginia and other 13 colonies along the Atlantic coast. Then there are Irish, Germans, French, Dutch, Swedes, Poles and Jews scattered in European countries. Subsequently, African blacks were also sold here in large numbers as slaves, and their population gradually accounted for one tenth. These are the early immigrants from America. After the founding of the United States, immigrants from various countries continued to enter the United States, mainly Europeans, but Asians also began to appear. It is worth mentioning that after the Opium War, many poor people along the coast of China were "sold pigs" and sent to the United States as "coolies". They are the earliest overseas Chinese and Chinese in America.
