On Good Friday, April 14, 1865, just five days after the end of the Civil War, President Abraham Lincoln was assassinated by a bitter Confederate sympathizer named John Wilkes Booth. Lincoln became an instant martyr, immortalized as the "The Great Emancipator." After Lincoln's assassination, the commonest of men tried to fill the gigantic void. Andrew Johnson, a self-educated tailor from Tennessee, became the 17th President of the United States, and the first to enter office after the murder of his predecessor. Rising above an impoverished childhood, Johnson was truly a self-made man, learning a useful trade and developing his own successful business. At the same time, he rapidly ascended the poltical ladder--Alderman, Mayor, State Legislator, Congressman, Governor of Tennessee, United States Senator, Military Governor of Union-occupied Tennessee, Vice-President, and President of the United States. As the only lawmaker from the South to remain in Congress after the outbreak of the Civil War, Andrew Johnson was the ultimate "Loyalist." In recognition for his dedication to the Union, Johnson was nominated as Abraham Lincoln's running mate in the 1864 presidential election. Barely a month into his vice-presidency, Johnson was thrust on the center stage of America politics. After Lincoln was murdered, the tailor from Tennessee ascended into the unenviable position of succeeding a legend. Johnson's obstinancy and rigid interpretaion of the Constitution soon placed him at odds with the Republican congression leadership and the national press. The bitter chasm widened as the Johnson presidency lurched forward, and ultimately led to his being the first President in American history to be impeached by the House of Representatives. By a single vote, Johnson avoided conviction by the Senate, and forfeiture of of office. After narrowly surving this constitutional crisis, Johnson's historical legacy was irrevocably damaged, and his hopes for an elected term as President were dashed. Returning to Tennessee after his presidency, Johnson was determined to return to political office. In remarkable fashion, he was elected to the United States Senate, marking the first and only time that a former President has returned to serve in that legislative body. Ambitous, lacking humility, and largely humorless, Johnson was unable to tolerate criticism. He angrily attacked his foes, once likening himself to Christ on the Crucifix. His combative personality and intemperate remarks readily allowed his enemies to portray him as vindictive and unstable. "The Loyalist: The Life and Times of Andrew Johnson" is a concise biography of the 17th President of the United States, focusing upon the tumultuous years surrounding the American Civil War. Sustained by courage and ambition, Johnson was inevitably doomed by petulance, leading to a remarkable rise, dramatic fall, and partial vindication.
