The final paper deals with the specificity of prisoners of war in the relevant wars of the 20th and 21st century. The initial part of the paper lays the legal foundations - those based on international law of war and a series of agreements and conventions. The central part focuses on the historical overview of the role, significance and position of prisoners of war through both world wars, as well as in the conflicts that resulted from the disintegration of Yugoslavia, where the Homeland War (1991-1995) will be in the highlight. The last part of the paper deals with the current topic - the Russian invasion of Ukraine, and clarifies the hitherto treatment of prisoners of war on both sides of the conflict. The conclusion, which is at the end of the paper, has a dual role: in addition to giving a brief summary of the entire paper, it also provides the author's reflections on the topic, as well as predictions for future joint efforts to better treat prisoners of war.
