The United States' "Westward Expansion" lasted for a century. Why did it take so long?

Because the westward expansion movement of the United States is a large-scale immigration process. The movement itself is an expansion process from east to west. It is also a cruel movement against the Indians. In the final analysis, they What people should care about is not the length of his time, but what people should care about is the consequences he brings.

This movement began at the end of the 18th century and ended from the late 19th to the early 20th century. All in all, the Westward Expansion Movement massacred a large number of Indians, and then drove the survivors to the desolate areas of the west, successfully wiping out the Indians, one of the major human races, and leaving very few in number. This is not an evocative movement, but an act of aggression by the United States to annex other people's places in order to expand its own territory. This movement wiped out many Indian cultures and turned the movement into a massacre.

In 1983, the British opened up to the United States a large area of ??Indian land from the west of the Appalachian Mountains to the west Mississippi River. Then in May 1830, the then President of the United States, Andrew Jackson, agreed to settle the Indians west of the Mississippi River. This act also enabled the colonial enterprise to develop rapidly in this area. A large number of immigrants headed west one after another, opening up the Multiple areas?. In 18-10 and 18-19, the United States obtained Florida. In 1846, it obtained the United States from the United Kingdom and extended the 49-degree north latitude boundary of the United States to the Atlantic coast. After the war between the United States and Mexico broke out from 1846 to 1853, the United States purchased a large area of ??Mexico. Until 1853, the United States expanded its territory to 7.85 million square kilometers, more than seven times the territory during the independence period.

Bandits and bandits are just that. During the colonial period, 13 million Indians were killed in Spanish territories, and about 10 million were killed in Brazil. During the United States' westward expansion, about 1 million Indians were killed. It was this method of massacre that reduced the Indian population base. Although there were many Indian resistance actions at that time, they were all bloody suppressed. A country that now claims to be civilized was merciless when it expanded its territory at that time. It even offered heavy rewards for the heads of Indians after the massacre. This was so bloody and shameless.
