Florida is a village in Monroe County, Missouri, United States. It is located at the intersection of Missouri Route 107 and County Road U on the shores of Mark Twain Lake. The population was nine residents according to the 2000 United States Census. Following the 2010 Census the village was reported as uninhabited. The Mark Twain Birthplace State Historic Site is located in Florida, with Mark Twain State Park nearby.
Mark Twain, born Samuel Langhorne Clemens in Florida on November 30, 1835, said of his birthplace it was '"a nearly invisible village"  and
"The village contained a hundred people and I increased the population by 1 per cent. It is more than many of the best men in history could have done for a town."
At the time of Twain's birth, the village of Florida was hardly much older than he, having been laid out in the winter of 1831. The founders were Robert Donaldson, Joseph Grigsby, Hugh A. Hickman, a Doctor Keenan, John Witt, and Major W.N. Penn. Hickman owned and operated a mill approximately one half-mile south of Florida, while Penn had a dry goods store near there as well. Penn soon moved his store into Florida proper, becoming the towns first business. In the early years there was some hope of the town becoming a regional point of commerce and shipping. Located at the confluence of the North, South, and Middle forks of the Salt River. Located 48 miles upstream from its mouth emptying into the Mississippi River at Louisiana, Missouri, this strategic location of Florida was felt to be a potential "growth center" in the settlement of northeast Missouri. For example, John Clemens, father of Mark Twain, along with other investors, had formed the Salt River Navigation Company in 1836 in hopes of developing this water commerce. Several boatloads of flour were shipped from Hickman's mill to the Mississippi and returned with sugar, coffee and manufactured goods. However fickle river levels on the Salt made consistent shipping via barge or riverboat impractical. Having no railroad and with river shipping no longer an option, Florida was destined to remain a small village attending to the commerce needs of area farmers. The Clemens family, seeking better opportunities, left Florida for Hannibal, Missouri when young Samuel was around five years old. He would continue to visit Florida for extended summer vacations at his uncle John Quarles farm. Such summer memories and social interactions with Quarles house servants formed many of the sketches and perspectives that Clemens placed in his novels. The Quarles farmhouse remains as an active archeological project available to the public near Florida.
As part of the area known as Little Dixie, Monroe County's residents largely sided with the Confederacy during the American Civil War. The area around Florida was the scene of two small battles during the conflict. The first happened in July, 1861. Brigadier General Thomas A. Harris of the pro-Confederate Missouri State Guard had established his headquarters at Florida in June, and by early July he had nearly five hundred troops in the immediate vicinity under his command. When informed of this growing threat by Union sympathizers and Federal spies, Union commander Nathaniel Lyon in St. Louis ordered action be taken. On July 8, 1861 Federal forces consisting of six companies of regular infantry plus a company of Hannibal Home Guards—around six hundred men total—and a cannon with crew set out from Palmyra, Missouri toward Florida.
Learning of their approach, General Harris sent a unit of approximately fifty men to reconnoiter and harass the Federals. The opposing forces clashed at a place called Hagar's Hill four miles north of Florida. Hidden by thick timber and brush, the State Guardsmen ambushed the Federals, opening fire at very close range. The Federal troops quickly regrouped and returned heavy fire with their superior numbers, causing the State Guard force to flee. Casualties were surprisingly light with one State Guardsman killed and a few others slightly wounded. The Federals had none killed but three seriously wounded. Meanwhile the bulk of State Guard and various Confederate bushwhackers had outflanked the Federals and attacked Monroe City, Missouri and its vital railroad line. This forced the Federals to turn back from the march on Florida.
The second Civil War action to happen near Florida occurred about one year later. On July 22, 1862 a Confederate force (numbers vary between 300 and 400 men) under Colonel Joseph C. Porter were traveling south through Monroe County after a raid on Memphis, Missouri and the Battle of Vassar Hill in Scotland County. At Florida they were surprised by a detachment of Federal cavalry, approximately fifty men, under Major Henry Clay Caldwell. Despite being vastly outnumbered the Federals engaged Porter's force and a battle ensued for approximately an hour. After suffering six killed, twenty-two wounded, and two captured, Caldwell and his cavalry retreated to Paris, Missouri. Porter, having only one killed and three wounded, also left the area, continuing on toward Callaway County, clashing with Federal forces again on July 24 near Santa Fe and at the Battle of Moore's Mill on July 28.
Florida continued a pattern of slow growth after the Civil War, reaching its peak population of 280 residents in 1880. The 20th century was not nearly so kind to the community however, especially after World War II as businesses closed and families moved away to find better opportunities in cities. The construction of Mark Twain Lake in the mid-1960s permanently flooded some of the valuable farmland around Florida, although it opened more opportunities for recreation and tourism. In 1960 the state of Missouri created the Mark Twain Birthplace State Historic Site. Twain's birthplace was moved into a climate-controlled museum setting, which also contains exhibits and displays such as rare first edition books, a hand-written manuscript of The Adventures of Tom Sawyer, and furnishings from his home. A red granite monument elsewhere in Florida marks the original site of Twain's birth home.
