Menéndez Reaches Florida and Names San Agustín

August 28, 1565 — A name that would endure for centuries

On August 28, 1565, Spanish admiral Pedro Menéndez de Avilés reached the Florida coast during an expedition that would permanently change the history of the peninsula.

The date mattered. August 28 was the feast day of Saint Augustine of Hippo. Menéndez associated the place with the saint, and the name San Agustín — St. Augustine — would soon be given to the Spanish settlement established there.

Florida Memory records that Menéndez entered the harbor he called San Agustín on August 28. National Park Service histories likewise connect the name St. Augustine with Menéndez sighting Florida on Saint Augustine's feast day.

But the city itself was not founded on August 28. That occurred eleven days later.

Spain and France Compete for Florida

Menéndez had not crossed the Atlantic simply to explore.

France had established Fort Caroline near the St. Johns River in 1564. Spain considered the French settlement a threat to its claim to Florida and, importantly, to the sea routes used by Spanish treasure fleets traveling between the Americas and Europe.

King Philip II commissioned Menéndez to remove the French presence and establish a permanent Spanish foothold in Florida.

Menéndez arrived with settlers, soldiers, sailors, supplies, and the authority to establish a colony. The expedition therefore represented something different from many earlier voyages to Florida.

The Spanish intended to stay.

September 8: The Settlement Begins

On September 8, 1565, Menéndez and his settlers formally established St. Augustine.

They settled near the Native community of Seloy, associated with the Timucua people. Florida Memory records that the Spanish initially made use of a large Native structure at the site while constructing defenses around their new settlement.

A Mass accompanied the Spanish landing and establishment of the community.

From this precarious beginning grew the settlement that would become the oldest continuously occupied European-established city in what is now the continental United States.

Florida Before Jamestown and Plymouth

The date provides an important reminder about the chronology of American history.

St. Augustine was established in 1565. Jamestown followed in 1607. The Plymouth Colony was established in 1620.

By the time the Mayflower reached New England, Europeans had maintained a permanent community in Florida for more than half a century.

And long before any of them arrived, Native peoples had already lived throughout Florida for thousands of years.

Why August 28 Matters

August 28 did not mark the formal founding of St. Augustine. It marked the moment when the name San Agustín entered Florida's story.

Within days, Menéndez and his followers would establish a settlement. The struggle between Spain and France would turn violent. Fort Caroline would fall, and Spain would begin a colonial presence in Florida that—with an interruption during the British period—would influence the peninsula for centuries.

Today, more than 460 years later, the name chosen in connection with that August day remains on the map: St. Augustine, Florida.
