Not much. About the only link between the Revolutionary War and the Civil War is that the Civil War resulted from the decision made during the Revolutionary to keep slavery in a country (and slave holder President Thomas Jefferson) that said; "All Men are Created Equal". In 1776, the double standard of the USA regarding slavery was known far and wide. In England it took William Wilberforce and the Captain John Newton song, "Amazing Grace" to bring an end to slavery. In the USA, it took a Civil War, Frederick Douglas and President Abraham Lincoln to bring an end to slavery. Apart from the slavery issue, I can't think of any other link between the Revolutionary War and the Civil War.
