Information: - The Confederate States, officially the Confederate States of America (CSA or C.S.), commonly referred to as the Confederacy, was an unrecognized breakaway country of 11 secessionist slave states existing from 1861 to 1865. It was originally formed by seven slave states South Carolina, Mississippi, Florida, Alabama, Georgia, Louisiana, and Texas in the Lower South region of the United States whose regional economy was mostly dependent upon agriculture, particularly cotton, and a plantation system that relied upon the labor of African-American slaves. - The Arkansas - class ironclads were a pair of casemate ironclads built for the Confederate States Navy during the American Civil War . - An ironclad is a steam-propelled warship protected by iron or steel armor plates used in the early part of the second half of the 19th century. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859. The British Admiralty had been considering armored warships since 1856 and prepared a draft design for an armored corvette in 1857; in early 1859 the Royal Navy started building two iron-hulled armored frigates, and by 1861 had made the decision to move to an all-armored battle fleet. After the first clashes of ironclads (both with wooden ships and with one another) took place in 1862 during the American Civil War, it became clear that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. This type of ship would come to be very successful in the American Civil War. - The American Civil War was a civil war in the United States fought from 1861 to 1865. The Union faced secessionists in eleven Southern states grouped together as the Confederate States of America. The Union won the war, which remains the bloodiest in U.S. history. - The casemate ironclad is a type of iron or iron-armored gunboat briefly used in the American Civil War. Compared to the turreted ironclad warships that became standard, the casemate ironclad does not have its cannons in an armored gun deck, but instead has a casemate structure (often sloped) on the main deck housing the guns. As the guns are carried on the top of the ship yet still fire through fixed gunports, the casemate ironclad is seen as an intermediate stage between the traditional broadside frigate and the modern warships. - The Navy of the Confederate States (CSN) was the naval branch of the Confederate States Armed Forces, established by an act of the Confederate Congress on February 21, 1861. It was responsible for Confederate naval operations during the American Civil War, fighting against the U.S. Navy.
