Social cohesion is an academic field of study, which has gained importance especially in recent years. At the same time, it has also became a high politics issue for states too. The concept of Social Cohesion, which aims at balanced development with various arguments for the prosperity of individuals and society, has different approaches from many different perspectives. Therefore, there is no single definition accepted by everyone about the Social Cohesion. So, this concept, which attracts the attention of international institutions and national governments, has also become a goal of importance for the European Union with its supranational structure. The European Union's vision of founding is to bring together European and European states that have become impoverished due to years of wars under a common umbrella, to ensure peace and prosperity. Hereby, the eventual aim is to make peace and fair sharing dominate the continent. Primarily, the “Citizens' Europe” process, which was intended to be created by ensuring the fusion among Europeans, could not be brought to the desired level due to various crises and cultural differences. Subsequently the winds of globalization, which has prevailed in recent years, is making social cohesion more and more difficult. Based on this point, this study while examining the concept of social cohesion in various aspects, also analyzes the efforts, goals and current level of the European Union in the field.
