John Slidell (1793 – July 26, 1871) was an American politician, lawyer and businessman. Originally a native of New York, Slidell moved to Louisiana as a young man and became a staunch defender of southern rights as a U.S. Representative and Senator.

Early life

He was born to the merchant John Slidell and the former Margery Mackenzie, a Scot. He graduated from Columbia University (then "College") in 1810. In 1835, Slidell married the former Mathilde Deslonde, and they had three children, Alfred Slidell, Marie Rosine (later comtess de St. Roman), and Matilda (later baronness d'Erlanger).

Merchant, lawyer, politician

Slidell was in the mercantile business in New York before he relocated to New Orleans. He practiced law in New Orleans from 1819-1843. He was the district attorney in New Orleans from 1829-1833. He also served in the state's House of Representatives. Though he lost an election to the United States House in 1828, he was elected in 1842 and served a term and a half from 1843-1845, as a Democrat. [The Historical Atlas of Political Parties in the United States Congress, p. 97] He served as minister plenipotentiary to Mexico from 1845-1846.

Prior to the Mexican-American War, Slidell was sent to Mexico, by President James Knox Polk, to negotiate an agreement whereby the Rio Grande River would be the southern border of Texas. He also was instructed to offer, among other alternatives, a maximum of $30 million for California by Polk and his administration. With the guidance of General Zachary Taylor, U.S. troops were stationed at the U.S./Mexico border, ready defend against Mexican attack. The Mexican government rejected Slidell's mission. After Mexican forces attacked at Matamoras the United States declared war on Mexico on May 13, 1846.

At the Democratic Convention in Charleston, South Carolina, in April 1860, Slidell plotted with "fire-eaters" such as William Lowndes Yancey of Alabama to stymie the nomination of the popular Northern Democrat Senator Stephen A. Douglas of Illinois.

Civil War

During the American Civil War John Slidell was one of the two CSA diplomats involved in the "Trent Affair" in November, 1861. After having been appointed the Confederate States of America's commissioner to France in September, 1861, he ran the blockade from Charleston, South Carolina, with James Murray Mason of Virginia. They then set sail from Havana on the British mail boat steamer RMS "Trent", but were intercepted by the U.S. Navy while en route and taken into captivity at Fort Warren in Boston. After the resolution of the "Trent" Affair, the two diplomats set sail for Europe on January 1, 1862.

John Slidell was a brother of Alexander Slidell Mackenzie, a naval officer who commanded the USS "Somers" on which a unique event occurred in 1842 off the coast of Africa during the Blockade of Africa. In that incident, three crewmen were hanged after being convicted of mutiny at sea. Mackenzie reversed the order of his middle and last names to honor a maternal uncle.

Another brother, Thomas Slidell, was chief justice of the Louisiana Supreme Court. He was also the brother-in-law of the American naval Commodore Matthew C. Perry, who was married to Slidell's sister, Jane. Perry is remembered for opening United States trade with Japan in 1853.

Later life

Slidell moved to Paris, France, after the Civil War. He died in Cowes, Isle of Wight, England. He is interred in the Saint-Roman family private cemetery near Paris. He, Judah P. Benjamin and A. Dudley Mann were among the high-ranking Confederate officials buried abroad.
