Racial discrimination in the United States has a long history, starting from the declaration of independence 1776. 1776 The independence declared by the United States is only the independence of whites, excluding blacks, which is also a big stain of the 1787 American Constitution. During the civil war, in order to reverse the situation, the federal government announced the abolition of black slavery, which made blacks gain equal legal status, but it did not change the weak position of black groups. Racial discrimination is still widespread in the United States. In the 20th century, blacks felt that their status was not truly equal, and racial discrimination and oppression still deeply troubled them. After a series of campaigns against racial discrimination (such as Martin Luther King), the status of African-Americans has risen, but racial discrimination still exists in the United States today, and African-Americans and Asians are still discriminated against in the United States, which can be seen from the abuse and death of young soldiers in China by white soldiers in Afghanistan this year. The United States still has a long way to go to eliminate racial discrimination.
