Answer:
The 14th Amendment was the result of the end of the Civil War.
Definition of the 14th Amendment
The 14th Amendment gave citizenship to all people born in America (excluding Native Americans). It states that the privileges of citizenship shall never be taken away from American citizens. Specifically, it is known for saying everyone has "equal protection under the law". The Amendment was made to ensure that African Americans could have equal legal protection.
Significance
Part of the significance was that it expanded citizenship. Now, former slaves could have citizenship and experience the liberties of citizenship. Additionally, it ensured that African Americans had access the due process and other constitutional rights. However, it should be noted that the Amendment failed to actually protect black Americans or ensure equal rights. Segregation and Jim Crow laws continued to discriminate against African Americans.
