This article examines the Turkish-Armenian relations, its development throughout the history and the situation between those two countries since Recep Tayyip Erdogan became the prime minister of Turkey in 2003 resulting in the change of the Turkish foreign policy. The main focus is on the problems between Turkey and Armenia stemming out from the different view on the happenings in 1915 and the recognition of the so called Armenian genocide. The article analyzes the decision-making of the individuals, the international organizations and the states when it comes to the question of the so called Armenian genocide and the reasons of the decisions made by individuals and states. These decisions are subjected to criticism on the basis of the reality image theory by Ibrahim Canbolat (1993) and the Thomas theorem (1928) as well as other criteria. States are the most important actors in the article because they form the foreign policy and the influence of this particular problem of the decisions of states influences the relations between Turkey and the EU as well as other world powers. Turkey's importance and image are still worsened due to these reasons and unfortunately, it seems that states have no interest in finding the truth.
