The study will focus on how the Crimean Tatars situation from a human security perspective has changed over time. To fully understand the depth of how and why, the thesis will start by introducing some of the issues faced by the Crimean Tatars as a minority group and then providing a historical background. With help from the theoretical framework of “Human Security” (Tadjbakhsh & Chenoy, 2007) the study is comparing how secure the Crimean Tatars are perceived to be under Ukrainian rule 1991-2014 and Russian rule 2014-present day. In the thesis it will be further examined if the Tatars security has in fact been compromised. Concluding that the rules over Crimea, Ukrainian and Russian, has both comprised the security of the Crimean Tatars but in different ways and sometimes more or less within certain categories of the Human Security framework. In the later years there are especially three categories that has been more prominent threats which becomes clear in the findings chapter.
