What is "acuera"

Acuera was the name of a town and a province or region in central Florida during the 16th and 17th centuries. The people of Acuera spoke a dialect of the Timucua language. The town was raided by soldiers of Hernando de Soto's expedition in 1539, and was known to the French in their brief tenure (1564-1565) in northern Florida. Acuera came under Spanish influence late in the 16th century, and two or three Spanish missions were established in the Acuera province in the 17th century.
