Racism in the United States has manifested itself mostly among Anglo-Saxon Americans against people of African, Asian, Italian, Polish, Native American, Latin American, and other immigrant descent. It should be emphasized that a religion, such as Islamic, nationality, language, customs or culture does not determine a race. This is denoted by naming racism to Chinese, Israelis, Russians, Mexicans or Americans who are multiracial countries and regions, or continents like Asia, which has diversity of ethnic groups. During this time Jim Crow laws emerged that consisted of racial segregation in all public facilities. After his release during the civil war by Abraham Lincoln, the southern states, resentful of his defeat during the civil war, enacted a variety of laws to discriminate against black citizens. This phenomenon occurred during the post-civil war period of "reconstruction". With the election of Rutherford B. Hayes as the nineteenth president, discrimination spread to the northern states that initially had it more gently, to the point that at the beginning of the 20th century the severity of discrimination and racism could be seen in places like New York, Boston, Detroit, Chicago and Los Angeles. According to a study between 1830 and 1950, 4,000 blacks were lynched in the United States. That, according to the source, many times were a public and popular spectacle with sometimes thousands of witnesses. Where 25% of the accusations were abuse against white; where recognition of the victim was not required from the aggressor and that caused the emigration or ethnic purity of 6,000,000 blacks to the North and West of the country. As the states could not eliminate the rights of blacks, which are guaranteed in the constitution, "segregation" that was legal for many years under the idea of "Separated but Equal" or in Spanish "Separated but Equal" was used instead. " The idea was that as long as the opportunities that were granted were equal for both races, this was legal. The reality was that educational, employment, housing, and economic opportunities were not the same. For example, white public schools received more money and new supplies, while black schools received as little money as possible.
