"While Jefferson Davis was historically correct when he said that the 'people' in 1776 referred exclusively to free white men, that needed correction. African Americans, women, and diverse minorities had to be included if the promise of the revolution was to be realized. Inclusionary moves inevitably triggered reactionary responses. After the Civil War, when former slaves were granted citizenship andimmigrants flooded into the United States from southern and eastern Europe, lineage societies such as the Sons of the American Revolution and the Daughters of the American Revolution set a standard for the true American: revolution pedigree and white. In the mid-20th century, when African Americans tried to cash in on promises of equality that remained unfulfilled, they met a fierce backlash that evolved, with time, into "Make America Great Again" as proclaimed by Donald Trump."
