Tennessee was the first state to rejoin the Union by the summer of 1865. For much of the war Tennessee already had a Unionist state government in place. Andrew Johnson was appointed General and military governor by Lincoln after the fall of Nashville. When Johnson became Lincoln's VP rewas replaced by the ardent Unionist Parson William Gannaway Brownlow, publisher of THE KNOXVILLE WHIG AND REBEL VENTILATOR. Tennessee had a Unionist Legislature, Supreme Court along with established local law enforcement in place in much of the state, a revised constitution, and was if I recall correctly the 1st state to adopt the 13th and 14th amendments north or south but certainly in the former CSA. Tennessee was therefore not "occupied' by federal troops nor did they suffer as dearly from carpet baggers. Read recently that from 1865 til about 1880 Knoxville Tennessee suffered the highist per captita murder rate in the nation a record not matched until LA in the 1990's. Former Rebs and former Yanks had scores to settle. One of the most famous involved the Hazen family. The story was retold by Mark Twain in LIFE ON THE MISSISSIPPI. Still another involved the shotgun death of former CS Maj Gen James Holt Clanton in broad daylight on Gay Street by the son of Andrew Johnson's defense attorney during the President's impeachment trial. That and 7 other such stories are available from this web site in my book titled BROKEN SWORDS.
