Through a political party, an organized group of people strives to achieve and implement their goals and ideas. To establish a political party in Croatia, it is required 100 business capable citizens. Any established political party in the Republic of Croatia is registered in the Register of Political Parties. For organized people with ideas and energy, each election is a chance to pursue their ideas and goals through its political party and to participate in decision-making. For this reason, in Croatia, where there is a very large number of political parties, the time before elections is also the time of more frequent establishment of political parties. The survival and functioning of new political parties is different. Some political parties have been established and have never achieved a more remarkable result, some newly-formed political parties succeed in one election, but at other elections disappear, and the individual becomes a constant at the political scene. The political party's success in the elections and its survival after the election is largely influenced by the political campaign and political marketing that seeks to enhance the eligibility of a candidate (political parties, programs) of the electoral potential, to bring it closer to a greater number of voters, noticeable difference in relation to other candidates or opponents and by minimal means optimize the number of votes that is important during the campaign. Although political marketing in Croatia can not be compared with developed countries, every day and with every new election, political parties and politicians are increasingly aware of the importance and impact of political marketing, both for existing parties and candidates as well as for newly established and newly emerged. This paper will analyze the success of newly founded political parties in the Republic of Croatia, and that is the theme of this final work.
