Camden is a city in and the county seat of Ouachita County in the south-central part of the U.S. state of Arkansas. The city is located about 100 miles south of Little Rock. Situated on bluffs overlooking the Ouachita River, the city developed because of the river. The recorded history began in 1782 when a Spanish military post was established on the site of an old French trading post called "Écore à Fabri." When Ouachita County was formed in 1842, American settlers changed the name to Camden. The city became an important port during the steamboat era when Camden became known as the “Queen City” of the Ouachita. In 1864, Camden became the unintended focus of the Red River Campaign, a major Civil War effort resulting in several significant battles.
