The early European presence in California and in the American Southwest in general is identified with missions. Although missions were equally important in Spanish Florida and at an earlier date, the average American does not associate missions with Florida or Georgia. Indeed, as David Hurst Thomas observed in a recent monograph on the archaeological exploration of a site of the Franciscan mission of Santa Catalina de Guale on Georgia's St. Catherines Island, the numerous missions of Spanish Florida have remained little known even in scholarly circles. And as Charles Hudson has noted, this ignorance or amnesia has extended to awareness of the native peoples who inhabited those Southeastern missions or were in contact with them, even though these aboriginal inhabitants of the Southeast “possessed the richest culture of any of the native people north of Mexico … by almost any measure.” Fortunately, as Thomas remarked in the above-mentioned monograph, “a new wave of interest in mission archaeology is sweeping the American Southeast.” This recent and ongoing work holds the promise of having a more lasting impact than its historical counterpart of a half-century or so ago in the work of Herbert E. Bolton, Fr. Maynard Geiger, OFM, Mary Ross, and John Tate Lanning. Over the fifty odd years since Lanning's Spanish Missions of Georgia appeared, historians and archaeologists have made significant contributions to knowledge about sites in Spanish Florida where missions or mission outstations and forts or European settlements were established. But to date no one has compiled a comprehensive listing from a historian's perspective of the mission sites among them to which one may turn for the total number of such establishments, their general location, time of foundation, length of occupation, moving, circumstances of their demise and the tribal affiliation of the natives whom they served. This catalog and its sketches attempt to meet that need.
