The main subject of the thesis will discuss image shaping of politicians in the Republic of Croatia, following the example of Zoran Milanović – the president of the Rublic of Croatia and Andrej Plenković – the Prime Minister of Republic of Croatia. Key terms such as social networks, political communication, public opinion, image, credibility are defined. The backbone of the work is the research of public opinion through an online survey, in which the goal was to get positive or negative feedback on the shaping of the image on social networks of the two most important politicians in Croatia. Nowadays, social networks are experiencing their peak when it comes to politicians and their construction of identity and image on the Internet. Some of the politicians use the full potential that social networks offer, but there are also those who simply do not use the capacity in full. It will be analyzed whether the President of the Republic of Croatia, Zoran Milanović, and the Prime Minister, Andrej Plenković, are successful in using social networks for political purposes in Croatia, and what is the public oppinion about two mentioned politicians.
