February 14, 2020 5.23pm ESIt has become common to say that the United States in 2020 is more divided politically and culturally than at any other point in our national past.
As a historian who has written and taught about the Civil War era for several decades, I know that current divisions pale in comparison to those of the mid-19th century.
Between Abraham Lincoln’s election in November 1860 and the surrender of Robert E. Lee’s Confederate army at Appomattox in April 1865, the nation literally broke apart.
More than 3 million men took up arms, and hundreds of thousands of black and white civilians in the Confederacy became refugees. Four million enslaved African Americans were freed from bondage.https://theconversation.com/think-the-us-is-more-polarized-than-ever-you-dont-know-history-131600
