This thesis treats the identification between the Teucrians and the Ṯ-k-(k)-r, one of the so-called Sea Peoples. The hypothesis that the Teucrians and the Ṯ-k-(k)-r would be one and the same was proposed by the Egyptologist Lauth in 1867 and has since become the standard identification for this Sea People. The hypothesis is to-day up-hold by almost all scholars, regarding of discipline, devoted to the research of the Sea Peoples. The author has limited himself to the geographical links between these two peoples. Regarding the Teucrians, the ancient authors suggested three different areas of origin, Crete, Attica, and the Troad. Besides this, the Cypriot Salamis as well as the Cilician Olba have also been linked to this people. By studying the ancient texts relating to these five geographical areas and their respective connections to the Teucrians, the author has set out to test the historicity of the geographical connections. He has gone through the ancient texts and tried to find out the sources for their statements, the background and origin of these connections and their historical value. This has then been compared to the primary sources regarding the Ṯ-k-(k)-r, all of which originate from Egypt and the 20th Dynasty. The results of this survey is that none of the ancient accounts can be verified, with certainty, with information received from sources contemporary with the Sea Peoples. Furthermore, it is also impossible to prove that the Teucrians were an historical people and thusly their identification with the Ṯ-k-(k)-r is very problematic. Of the geographical areas, it is only Cyprus that with certainty can be linked to the Sea Peoples, but probably not with the Ṯ-k-(k)-r but with the D-n-n.
