No. Spain attempted but failed to establish a permanent colony in present-day South Carolina in 1526.
Lucas Vázquez de Ayllón, a wealthy Hispaniola official, secured a royal charter and led 600 colonists (including enslaved Africans, women, children) to Winyah Bay near modern Georgetown, SC. They founded San Miguel de Gualdape — the first European settlement in the continental US (predating St. Augustine by 39 years).
By November 1526, 150 survivors abandoned the settlement, sailing to Hispaniola. The exact site remains archaeologically unconfirmed.
• First European colony in US territory
• First enslaved Africans in present-day US
• First slave rebellion in North America
• Demonstrated Spanish interest in the region — later contested by France (Charlesfort, 1562) and England (Charlestowne, 1670)
Spain's 1526 effort failed, but it wrote the first European chapter in South Carolina's history.
