This book is the result of more than twenty years of archaeological research conducted on the small island of Uvea (Wallis) in Western Polynesia by a team led by Daniel Frimigacci, archaeologist CNRS. The general inventory of ancient sites conducted with the ethnologist Bernard Vienne , through the three customary districts of Hihifo, Hahake and Mu'a, has identified more than 300 different sites, including ceramics sites, ancient villages, fortifications and monumental constructions, large burials, etc. The stratigraphic excavations carried out on the Utuleve site revealed traces of the earliest human occupation, linked to the arrival of Lapita populations in Uvea about 3000 years ago. They also made it possible to define the various stages of the island's ceramic chronology and to date the appearance of the traditions of monumental constructions. Other excavations, carried out in particular on the large ceremonial platform of Talietumu and on a burial of the site of Atuvalu, in connection with the data of oral traditions, made it possible to understand the emergence of the traditional dynastic organization pre-Christian and the influence of Tongan royalty about 500 years ago. The archaeological synthesis of Uve'a's past proposed in this scientific work, contributes significantly to refine our knowledge of the multi-millennial history of Western Polynesia.
