Elihu Benjamin Washburne (September 23, 1816 – October 22, 1887) was an American politician. A member of the Washburn family, which played a prominent role in the early formation of the United States Republican Party, he served as a congressman from Illinois before, during and after the American Civil War. He was a political ally of President Abraham Lincoln and General (later President) Ulysses S. Grant. During Grant's administration, Washburne was the 25th United States Secretary of State briefly in 1869, and was the United States Minister to France from 1869 to 1877.

In his youth, when his family became destitute, Washburne left home in Maine at the age of 14, to support himself and further his education. After working for newspapers in Maine and studying law, Washburne passed the bar and moved to Galena, Illinois, where he became a partner in a successful law firm. Washburne was elected to the U.S. House of Representatives in 1852 and served from 1853 to 1869, which included the American Civil War and the first part of Reconstruction. While advocating Lincoln's war policy, Washburne sponsored an up-and-coming Grant; they were acquainted because Grant had moved to Galena shortly before the war to work in his father's leather goods business. Washburne advocated for Grant's promotions in the Union Army, and protected him from critics in Washington and in the field. Washburne was Grant's advocate in Congress throughout the war, and their friendship and association lasted through Grant's two terms as president.

As a leader of the Radical Republicans, Washburne opposed the Reconstruction policies of President Andrew Johnson and supported African American suffrage and civil rights. Washburne was appointed United States Secretary of State in 1869 by President Grant, out of respect for his championship of Grant's career during the Civil War, and to give Washburne diplomatic clout after being appointed minister to France. Washburne's tenure as Secretary of State lasted for only eleven days, but he served in France for eight years, where he became known for diplomatic integrity and his humanitarian support of Americans, other neutrals, and Germans in France during the Franco-Prussian War. For his efforts, he received formal praise from governments in both France and Germany. Washburne's friendship with Grant ended after the contentious 1880 Republican convention, when Washburne was a candidate for president. He did not garner wide support, but Grant had been the front runner for an unprecedented third term, and was disappointed when the party eventually turned to dark horse James A. Garfield. In retirement, Washburne published a biography of anti-slavery politician Edward Coles, and a memoir of his own diplomatic career in France.

Early life, education, and legal career Elihu Washburne was born on September 23, 1816, in Livermore, when Maine was part of Massachusetts. He was the third oldest of eleven children born to Israel and Martha (née Benjamin) Washburn. Washburne was the grandson of Captain Israel and Abiah (King) Washburne. His grandfather served as an officer in the Continental Army during the American Revolution and was a descendant of John Washburne, who served as Secretary of the Plymouth Colony while in England. John Washburne was a Puritan colonist who emigrated to America in 1631 and settled in Duxbury, Massachusetts.

Washburne's father settled in Maine in 1806 and set up a shipbuilding trade at Whites Landing on the Kennebec River in 1808. Following Puritan heritage, Israel was a strict disciplinarian and Washburne and his siblings were instructed in the Bible and put to work daily in the fields and on other chores, with no time for leisure. During the winter months Washburne attended district schools that used "birch rod" corporal punishment. Washburne's family fell on financial hard times in 1829, and his father, who was then in the mercantile business, was forced to sell his general store. The family was destitute and forced to rely on farming for subsistence, while Washburne and several of his brothers had to fend for themselves. At the age of 14, Washburne added the letter "e" to his name, as was the original ancestral spelling, and left home in search of education and a career.

After attending public schools, Washburne worked as a printer on the Christian Intelligencer in Gardiner, Maine, from 1833 to 1834. From 1834 to 1835 Washburne taught school and from 1835 to 1836 he worked for the Kennebec Journal in Augusta, Maine. Washburne attended Maine Wesleyan Seminary, studied law with Judge John Otis, and completed his legal studies with a year at Harvard Law School from 1839 to 1840.Carroll (1883), Twelve Americans Their Lives And Times, pp. 402–404 In 1840 he passed the bar exam, and moved west to Galena, Illinois. In Galena, Washburne entered into law partnership with Charles S. Hempstead.

Marriage and family On July 31, 1845, Washburne married Adele Gratiot, the niece of his law partner and the daughter of Colonel Henry Gratiot and Susan Hempstead Gratiot, members of one of Galena's most prominent families. Washburne had met Adele shortly after arriving in Galena; she was 10 years younger than Washburne, and known to be attractive, well-educated, and charming. The Washburnes had seven children including sons Gratiot, Hempstead, William P., and Elihu B. Jr., and daughters Susan and Marie L. The Washburnes were married for 42 years, which ended with Adele Washburne's death, 7 months before Elihu’s passing.

U.S. Congressman (1853–1869)

Washburne became active in politics as a Whig, and served as a delegate to the Whig National Convention in 1844 and again in 1852. In 1848 he was an unsuccessful candidate for Congress.

In 1852, Washburne was elected to the United States House of Representatives. He was reelected eight times, and represented northwestern Illinois from 1853 to 1869. While in Congress, Washburne was chairman of the Committee on Commerce (34th Congress, and 36th through 40th Congresses), and the Committee on Appropriations (40th Congress).

In 1854 Washburne supported Abraham Lincoln's unsuccessful candidacy for the United States Senate. In the mid-1850s the Whig Party dissolved, and the Republican Party was founded as the major anti-slavery party. Washburne joined the Republican Party, and in 1856 supported its first candidate for president, John C. Frémont.

Washburne backed Lincoln's unsuccessful candidacy for the United States Senate in 1858. In 1860, Washburne enthusiastically supported Lincoln's successful presidential campaign.

American Civil War During Lincoln's presidency Washburne supported the Union. As a trusted friend, he advised Lincoln informally, and kept him abreast of political news from Illinois.

As Lincoln made his way to Washington, D.C., in early 1861 to begin his presidential term, his supporters feared an assassination attempt. Washburne consulted Winfield Scott, the commander of the Army, who increased security in Washington and the surrounding area. Lincoln arrived in Washington incognito on February 23, 1861, and Washburne was on hand to meet him.

Sponsored Ulysses S. Grant

Washburne was one of only a few men in Washington, D.C., who had previously known Ulysses S. Grant, a fellow resident of Galena.Catton (1969), p. 3 Grant was a graduate of West Point and had served in the Army for eleven years, including the Mexican–American War. Initially, Grant and Washburne seemed like an odd political pairing; Grant was a Douglas Democrat and Washburne an ardent abolitionist and founder of the Republican Party. Despite those differences, Washburne became an early and ardent Grant supporter, and helped secure his promotions to the general officer ranks.

Though Grant had no rank or commission at the start of the war, he took the initiative to recruit a company of volunteers in Galena, and accompanied them to Springfield, the state capital. Grant discussed with Washburne his hope that his West Point education and previous military experience would lead to a field command; Washburne promised to discuss the matter with Governor Richard Yates. Yates quickly offered Grant a militia commission to serve as mustering officer and continue training the volunteer units which were being raised to rapidly expand the Army. Grant accepted, but continued his efforts to obtain a field command.

With Washburne's sponsorship, Grant was commissioned a colonel of volunteers on June 14, 1861, and appointed to command the 21st Illinois Volunteer Infantry Regiment. During his command of the regiment and through the Vicksburg Campaign, Washburne kept in close touch with Grant through his brother, Major General Cadwallader C. Washburn.Catton (1969), p. 26

Washburne continued as Grant's advocate and defender in Washington. In September 1861, Washburne sponsored Grant's promotion to brigadier general and command of a brigade, and supported his subsequent promotion to major general and assignments to district, field army, and military division command. Washburne was also an advocate for Grant's promotion to lieutenant general and command of the entire Union Army. During the war, Grant aligned himself with the Republican goals of ending slavery and incorporating African Americans into the military. His changed political outlook and success on the battlefield made him a likely contender for president as a Republican, and Washburne supported Grant's successful campaign in 1868. Grant was in Washburne's home in Galena when he heard the news of his election.

Investigation into Western War Department During the first months of the Civil War under President Lincoln, Washburne launched an investigation into corruption charges of General John C. Frémont's Western War Department. Lincoln had appointed Frémont commander of the Western War Department in July 1861. Rumors spread of a "horde of pirates" under Frémont's authority of defrauding the army and the federal government and that Frémont himself was "extravagant". Washburne's investigation revealed that Frémont had awarded his California associates with lucrative army contracts. Also Frémont had favored sellers who were given exorbitant contracts for railroad cars, horses, mules, tents, and equipment that was inferior in quality. In October, Lincoln relieved Frémont of command on corruption charges and for insubordination.

Radical Republican leader Washburne became a leader of the Radical Republicans, those most ardently opposed to slavery, and was among the original proponents of racial equality. As a congressman, he served on the Joint Committee on Reconstruction which drafted the Fourteenth Amendment to the United States Constitution. After the Civil War, Washburne advocated that large plantations be divided up to provide compensatory property for freed slaves.

Secretary of State and Minister to France (1869–1877)

When Grant became president in 1869, he appointed Washburne to succeed William H. Seward as Secretary of State, with the understanding that he would hold the post only briefly and then serve as minister to France.Bunting III (2004) Washburne had been ill and confined to his home all through February, and told Grant that his "health would prevent [him] from holding the position for any length of time." He took the position on March 5, wrote his resignation letter on March 10, and left office on March 15 after his successor, Hamilton Fish, arrived from New York to take the position. His term remains the shortest of any Secretary of State. The Department sent 22 nominations to the Senate during his tenure.
