This article from Teaching Tolerance magazine observes that the history of slavery—which ended in the United States over 150 years ago—is still shaping contemporary patterns of school segregation through its influence on our social institutions and our reliance on historical precedent and local tradition. The history itself happened long ago, but its legacy is a contemporary phenomenon because our social realities today are informed by what happened yesterday—including our less flattering moments. So, although people today are not individually responsible for slavery, we are very much responsible for how we respond to that history. As academic researchers, we use this understanding to guide the questions we ask and attempt to answer. It is what led us to investigate whether counties with stronger attachments to slavery have a higher level of school segregation today. We found out the answer is yes, but not for the reasons you might think.
