Beginning in the second half of the 16th century, the Kingdom of Spain established a number of missions throughout la Florida in order to convert the Indians to Christianity, to facilitate control of the area, and to prevent its colonization by other countries, in particular, England and France. Spanish Florida originally included much of what is now the Southeastern United States, although Spain never exercised long-term effective control over more than the northern part of what is now the State of Florida from present-day St. Augustine to the area around Tallahassee, southeastern Georgia, and some coastal settlements, such as Pensacola, Florida. A few short-lived missions were established in other locations, including Mission Santa Elena in present-day South Carolina, around the Florida peninsula, and in the interior of Georgia and Alabama.
