John Slidell (1793 – July 9, 1871) was an American politician, lawyer and businessman. 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. He was the older brother of Alexander Slidell Mackenzie, a US naval officer.
He was born to the merchant John Slidell and the former Margery Mackenzie, a Scot. He graduated from Columbia University (then College) 1810. In 1835, Slidell married the former Mathilde Deslonde, and they had three children, Alfred Slidell, Marie Rosine (later [on 30 Sept. 1872] comtesse [Countess] de St. Roman), and Marguerite Mathilde (later [on 3 Oct. 1864] baronne [Baroness] Frederic Emile d'Erlanger).
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 from 1837-1838. 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. 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 would be the southern border of Texas. He also was instructed to offer, among other alternatives, a maximum of $25 million for California by Polk and his administration. Slidell hinted to Polk that the Mexican reluctance to negotiate might require a show of military force by the United States. Under the guidance of General Zachary Taylor, U.S. troops were stationed at the U.S./Mexico border, ready to defend against Mexican attack. The Mexican government rejected Slidell's mission. After Mexican forces attacked at Matamoros, the United States declared war on Mexico on May 13, 1846.
