This paper aims to analyse the impact of social media on the spread of radical terrorism. This impact is first explored as a general concept and then in Kosovo. An important issue is an impact that imams have had on the radicalisation of the people of Kosovo, especially regarding the content of videos, where imams indirectly persuade young people to revolt. Six categories are used to describe the process of radicalisation, such as propaganda, which includes recruiting, radicalising, inciting terrorism, then financing, planning, covert communications, open-source information, execution, and finally, cyberattacks. Finally, conclusions are given, both on what should be done now and the impact of radicalisation on Kosovar society.
