Impeachment of Andrew Johnson in the context of "George Boutwell"

Andrew Johnson (December 29, 1808 – July 31, 1875) was the 17th president of the United States, serving from 1865 to 1869. The 16th vice president, he assumed the presidency following the assassination of Abraham Lincoln. Johnson was a War Democrat who ran with Lincoln on the National Union Party ticket in the 1864 presidential election, coming to office as the American Civil War concluded. Johnson favored quick restoration of the seceded states to the Union without protection for the newly freed people who were formerly enslaved, as well as pardoning ex-Confederates. This led to conflict with the Republican Party-dominated U.S. Congress, culminating in his impeachment by the House of Representatives in 1868. He was acquitted in the Senate by one vote.

Johnson was born into poverty and never attended school. He was apprenticed as a tailor and worked in several frontier towns before settling in Greeneville, Tennessee, serving as an alderman and mayor before being elected to the Tennessee House of Representatives in 1835. After briefly serving in the Tennessee Senate, Johnson was elected to the U.S. House of Representatives in 1843, where he served five two-year terms. He was the governor of Tennessee for four years, and was elected by the legislature to the U.S. Senate in 1857. During his congressional service, he sought passage of the Homestead Bill, which was enacted soon after he left his Senate seat in 1862. Slave states in the Southern U.S., including Tennessee, seceded to form the Confederate States of America, but Johnson remained firmly with the Union. He was the only sitting senator from a Confederate state who did not promptly resign his seat upon learning of his state's secession. In 1862, Lincoln appointed him as Military Governor of Tennessee after most of it had been retaken. Johnson was a logical choice as Lincoln's running mate in 1864 because Lincoln wanted to send a message of national unity in his re-election campaign. Following their victory, Johnson became vice president.

The impeachment trial of Andrew Johnson, 17th president of the United States, was held in the United States Senate and concluded with acquittal on three of eleven charges before adjourning sine die without a verdict on the remaining charges. It was the first impeachment trial of a U.S. president and was the sixth federal impeachment trial in U.S. history. The trial began March 5, 1868, and adjourned on May 26.

The trial was held after the United States House of Representatives impeached Johnson on February 24, 1868. In the eleven articles of impeachment adopted in early March 1868, the House had chiefly charged Johnson with violating the 1867 Tenure of Office Act by attempting to remove Secretary of War Edwin Stanton from office and name Lorenzo Thomas secretary of war ad interim.

Benjamin Franklin Butler (November 5, 1818 – January 11, 1893) was an American major general of the Union Army, politician, lawyer, and businessman from Massachusetts. Born in New Hampshire and raised in Lowell, Massachusetts, Butler was a political major general of the Union Army during the American Civil War and had a leadership role in the impeachment of U.S. president Andrew Johnson. He was a colorful and often controversial figure on the national stage and on the Massachusetts political scene, serving five terms in the U.S. House of Representatives and running several campaigns for governor before his election to that office in 1882.

Butler, a successful trial lawyer, served in the Massachusetts legislature as an antiwar Democrat and as an officer in the state militia. Early in the Civil War he joined the Union Army, where he first gained renown when he refused to return escaped slaves, designating them as contraband of war, an idea that the Lincoln administration endorsed and that played a role in making emancipation an official war goal. Later in the war, he was noted for his questionable military skills and his controversial command of New Orleans, which made him widely disliked in the South and earned him the "Beast" epithet. His commands were marred by financial and logistical dealings across enemy lines, some of which may have taken place with his knowledge and to his financial benefit.

Presidential elections were held in the United States on November 3, 1868. In the first election of the Reconstruction Era, Republican nominee Ulysses S. Grant defeated Horatio Seymour of the Democratic Party. It was the first presidential election to take place after the conclusion of the American Civil War and the abolition of slavery. It was the first election in which African Americans could vote in the reconstructed Southern states, in accordance with the First Reconstruction Act.

Incumbent president Andrew Johnson had succeeded to the presidency in 1865 following the assassination of Abraham Lincoln, a Republican. Johnson, a War Democrat from Tennessee, had served as Lincoln's running mate in 1864 on the National Union ticket, which was designed to attract Republicans and War Democrats. Upon accession to office, Johnson clashed with the Republican Congress over Reconstruction policies and was impeached and nearly removed from office. Johnson received some support for another term at the 1868 Democratic National Convention, but, after several ballots, the convention nominated Seymour, who had formerly served as Governor of New York. The 1868 Republican National Convention unanimously nominated Grant, who had been the highest-ranking Union general at the end of the Civil War. The Democrats criticized the Republican Reconstruction policies, and "campaigned explicitly on an anti-black, pro-white platform," while Republicans campaigned on Grant's popularity and the Union victory in the Civil War.
