August marks 400 years since the first slaves arrived in America

This month marks 400 years since the first slaves arrived in America. 

In 1619, a ship with Africans landed at the English settlement that would later become Virginia. From about 1501 to 1875, Africans taken by slave traders were taken to the United States, South America, and the Caribbean. 

It led to a legacy of Jim Crow, lynching, and systemic racism. How far have we come in 400 years?
