Reconstruction began from 1865 until 1900. The 13th Amendment made slavery illegal, the 14th Amendment talked about rights as a citizen, and the 15th Amendment talked about equal rights. The Fifteenth Amendment banned voting discrimination based on race, color, or former slavery, allowing more Americans to engage in democracy. These measures didn't reduce tensions or resolve problems between liberated slaves and former slaveowners. The end of the war destroyed slaveowners' authority over freed slaves.
