Great article from CNN on why this year's Black History Month is pivotal. 

(CNN) 2019 marks the 400th anniversary of the arrival of 19 enslaved Africans, brought to mainland English North America for the first time. The Africans who disembarked in Jamestown were captives stolen first by Portuguese slave traders and then by English pirates who sold them into bondage in what would become the United States of America. This scene ultimately set the stage for more aggressive entrees into a global slave market by England and, over time, America.
