As early as the British colonization of the Americas, in order to massacre the Indians, a reward system for the scalps of Indians was established, and it was promulgated in the name of the Queen of England.
After the founding of the United States, Jefferson, the founding father of the United States, denounced in the Declaration of Independence that the British were too good to the Indians.
The basic task of the First Army Corps was to suppress the Indians.
From 1803 to 1892, regular U.S. troops and militias massacred Indians for nearly 100 years.
When there were few Indians left, the United States included Indians in its population, but racial discrimination continued to flourish.
For a long time, the number of American massacres of Indians was controversial.
In the 1980s and 1990s, some honest and rigorous scholars in the United States recalculated based on historical data. They found that when Columbus discovered the New World in 1492, the native American Population was between 30 million and 100 million, but by the 1970s, there were fewer than 800,000 Native American Indians left.
