Corinth is a city in and the county seat of Alcorn County, Mississippi, United States. The population was 14,573 at the 2010 census. Its ZIP codes are 38834 and 38835.HistoryCorinth was founded in 1853 as Cross City, so-called because it served as a junction for the Mobile & Ohio and Memphis & Charleston railroads. It was the town's early newspaper editor, W. E. Gibson, who suggested the name of Corinth, named for the city in Greece that also served as a crossroads.Corinth's location at the junction of two railroads made it strategically important to the Confederacy during the American Civil War. Confederate General P. G. T. Beauregard retreated to Corinth after the Battle of Shiloh, pursued by Union Major General Henry W. Halleck. General Beauregard abandoned the town when General Halleck approached, letting it fall into the Union's hands. Since Halleck approached so cautiously, digging entrenchments at every stop for over a month, this action has been known as the Siege of Corinth.
