The issue of peace and peace education is not new, rather it is an inexhaustible one. After World War II, the policies in field of education for peace took shape, which rather referred to the prevention and reduction of regional conflicts, to the training of citizens open to collaboration, to solving problems/ conflicts peacefully, tolerant towards other cultures and primarily other points of view and way of life. The Republic of Moldova in this sense was not an exception. But the war that was started by Russia in Ukraine totally changed the view on perception of war and the way of educating the population for peace and international collaboration. The focus is on approaching the problem from the perspective of national and international context, on identifying the psychological, physical, economic, political, social effects on the population, but also on identifying the perception of war by different social groups. At the same time, certain ways of education for peace are proposed in the context of the Republic of Moldova. Obstacles to the design and implementation of peace education are extensively analyzed, definitions of peace education are formulated, and general and peace education-specific competences are presented. The results of a study on the perception of war in Ukraine by the Moldovan society are also analyzed.
