The coming of the French Huguenots to Florida in 1564 and their establishment of an outpost known as Fort Caroline proved to be a remarkable event both for Spanish imperialism and the student of Indian customs and law. When the King of Spain learned that the French had invaded land which he considered to be his own and that renegade groups had raided nearby islands, he ordered Pedro Menendez de Aviles to organize a force and expel the invaders. Part of the contract signed by Menendez included the founding of two towns in Florida. Thus, when Menendez landed in Florida he established St. Augustine, the first permanent town to be founded within the bounds of the present United States by the Europeans.
