Thousands of black people in America were murdered between the end of the Civil War in 1865 and the Civil Rights Act of 1964. Some were hanged or shot. Others were beaten to death or burned alive. The attacks were called lynchings. Most of the murders took place in the American South. More than six million African-Americans fled north as a result. Very few of the killers were officially charged with the lynchings. Those who were charged were rarely punished. Now, a memorial has opened in Montgomery, Alabama, to remember that dark time in American history. The National Memorial for Peace and Justice is a project of the nonprofit Equal Justice Initiative. The organization says the site is the nation’s first to document racial inequality in America from slavery to the issues of today.
