The war in Ukraine has made public opinion and policy makers aware of the Russian Federation as a major threat to international security, but also to the internal security of the European Union. The military threat is only one of the instruments used by this state. For years, a different type of Russian activity in the EU has been observed, consisting in cre-ating an alternative picture of the situation in Ukraine, and interfering in political processes in selected countries. All these activities are aimed at undermining the cohesion and solidarity of the EU, which, from Moscow’s perspective, is a threat to its political interests as a result of the Union’s promotion of democratic values and principles and human rights in the international environment. The article presents selected disinformation campaigns carried out by Russia in the EU and then analyses the actions the Union has taken in response. Conclusions and recommendations were formulated in the end.
