This thesis explores the complexity of the identification processes of the people of Vis, observed through the concepts of islandness, diffraction and relationism. The purpose of the research was to find out which of the relations occur and how they influence creation of the Vis island identity. Through conducted ethnographic research a variety of data was collected, analyzed and methodologically enriched by sporadic observations, photographic documentation and analysis of Facebook posts. The material was further suplemented with semi-structured interviews which were conducted at different locations. The research demonstrated that understanding the complex island relationships, which go beyond spatial determinism, requires considering diverse relations that shape the intricate identities of the people of Vis. By moving beyond the island as a locality, they disperse across aquapelagic spaces, and through various socio-cultural practices, they construct beliefs about the "true" people of Vis, as well as other islanders, which function as cultural facts.
