On March 16, 1964 in conjuction with the Turkish government revoking The Convention of Residence, Commerce and Navigation (1930) Greek individuals who live and trade in Turkey, build a national identity even called “infidel”, are subjected to forced migration from the lands they consider as their homeland. Where they migrated, they are marginalized as "Turkish seed" and thus, their national identity is damaged. However, the place they call “home” still remains Istanbul. The revoked convention and the events that followed led to the re-examination of the concepts of Turkish and Greek national identity, language, religion and otherness and it also constitute the database of this study. Documentary Kayıp Vatan (Lost Homeland) was chosen for the sample of the study and was examined in the context of nationalism theories. As an approach, intertextuality was used and descriptive method was preferred. Fundemental concepts such as national identity, language, religion, homeland and otherness in nationalism literature were evaluated through the data in the documentary.
