This article provides an analytical discussion of the crisis of democracy and the rise of authoritarianism in the context of the Russia-Ukraine War. Some of the fundamental aspects of the post-Cold War international order are addressed in this respect, including emerging powers, anti-Westernism, authoritarianism, and new threats in international relations. It is argued that the post-Cold War period brought both stability and instability to the global world order. On the one hand, the United States' victory in the ideological conflict between the East and the West led to the dominance of the Western system and its influence in the Middle East and Central Eastern European region with the call for democracy. On the other hand, the growing intervention of the US in intra-state disputes through the deployment of NATO has become a major concern to Russia and many other nations along the eastern border. This intensified anti-Western sentiment in emerging countries, with the rise of many Authoritarian governments. Many of the conflicts that the world has witnessed since the end of the Cold War are the result of such anti-Western feelings. This resulted at the beginning of a new era of war and conflict on a global scale. Russia's war in Ukraine is one of the recent examples. Russia is attempting to maintain its sphere of influence to avoid joining NATO and the West, regardless of the cost or repercussions of the war. As a result of these conflicts between great powers, several new powers emerged, resulting in a multi-polar world order. Today, it is emphasized that the ability and willingness of great powers to cooperate in addressing these dangers will determine the course of the world.
