Today, the international community faces terrorist threats of a level and magnitude unknown in the past. Continuing terrorist attacks are causing significant changes in global security. Terrorists are not afraid to commit the most cruel and most inhumane acts. Recent global events have clearly demonstrated the fact that no country can solve security problems alone, let alone resolve such issues in the long term. All this actualizes the need for international solidarity in the fight against terrorism, for which it is necessary to study the national legislation of individual states in order to develop universal measures of influence, as well as to improve domestic anti-terrorism legislation. The presented article analyzes the current anti-terrorism legislation of the Slovak Republic, the interest in which is due to the fact that this country has common criminal legal views, doctrines, and very similar criminal legislation with the Russian Federation, which over the past decade has been significantly transformed under the influence of rec-ommendations of the European Union, and as well as the new challenges and threats it faced.
