何谓治崩三法?
The American victory in the Revolutionary War united 13 of the English-speaking settlements into the largest and most powerful political unit in the territory , even though those first 13 states hugging the eastern coast seem small compared with the country' s eventual size. As a result of the Revolution ,approximately 71 , 500 people out of a population of some 2. 5 million fled the new United States. Some were Loyalists - political or economic refugees whose loyalties to Great Britain remained strong; others were blacks seeking refuge from slavery. Immigration and the commercial slave trade after the war quickly restored the population to its former level. The Revolution also opened up the area west of the Appalachian Mountains to settlement , as fur traders and farmers were no longer confined by British settlement restrictions. Pioneering citizens , immigrants , and slaves moved west , displacing Native Americans who had hoped to preserve their cultures undisturbed by the expanding United States.The 17th and 18th centuries saw a growing importation of Africans into North America. After 1808 U. S. law forbade the importation of slaves from abroad , although some smuggling of slaves continued. Few people from Africa chose to come to the United States voluntarily (the free African population was small) because they were considered second-class citizens , and confined largely to the northern states. Large numbers of Europeans migrated to the United States in the early national period , drawn by the promise of freedom , cheap land in the West , and jobs in the first factories of the emerging industrial age. The influx of Europeans , the end of the slave trade , and the ongoing wars removing Native Americans meant that some of the racial diversity of the population was diminishing. By the early decades of the 19th century , a greater proportion of Americans were of western European and Protestant heritage than at the time of the Revolution.Over the course of the 19th century , the United States gradually absorbed the French colonists in the upper Midwest and in New Orleans , Louisiana; the Spanish and Russian colonists in the South , West ,and Northwest; and the territories of the Hawaiian people and other indigenous groups. Sometimes these territories were added by diplomacy , sometimes by brute force. European visitors were surprised at the diversity in nationalities and in religious and secular beliefs in early America , as well as the number of intermarriages between people of differing European heritages. There were also cross-racial births , sometimes voluntary and sometimes by force , but rarely within legal marriages. The population continued to grow through migration as well , driven in part by English , Irish , and German settlers who came in large numbers around 1848 to escape political repression and food shortages in Europe.31.
