Juan de Salinas was the governor of Spanish Florida from August 2, 1618 - October 28, 1624. Salinas arrived at Saint Augustine in 1618 to replace Juan Treviño de Guillamas as governor of the Spanish territory of La Florida. Under his administration, living conditions for Christianized Native Americans living in the Spanish missions of the territory deteriorated. They retreated to the forests of Guale and San Pedro (now Cumberland, Georgia) to escape near slavery.
