The paper delves into the intricate history of Fijian identity, proposing that external migrations, particularly from Tonga and Melanesia, played a crucial role in shaping contemporary Fijian culture. It critiques the traditional view of a singular Polynesian lineage, offering instead a polygenetic model that acknowledges diverse cultural influences. The paper examines key events such as Tongan migrations to Lau, which introduced significant social and political changes, and the mid-sequence ceramic transition in Viti Levu, indicating external cultural impacts. The narrative of the Kaunitoni migration further underscores the complexity of Fijian origins, integrating secret societies and rituals into local traditions. The conclusion calls for a more nuanced understanding of Fijian history, emphasizing both internal developments and external interactions over millennia. Methodological improvements are suggested for future research, advocating for scientific analyses to clarify migration patterns and cultural shifts in Fiji. Interdisciplinary approaches are encouraged to deepen the exploration of Fijian identity.
