In medieval times, Tuʻi Tonga invaders waged war against the islanders and took control. They installed their first chief and called him the Uveas which became ruling dynasty of the two islands; they are based at Mata-Utu even today. The fortifications which were built by the Tongans at that time have been unearthed at nearby Talierumu and Malama Tagata, during recent archaeological excavations of the area.
