Globalization is ubiquitous in the world. The word globalization is the most used word in the world, and it became relevant at the end of the 20th century. The globalization process does not affect all countries with equal force, but it is ubiquitous in all countries of the world with unequal effects on the development of individual countries. In modern conditions, globalization represents a stage in a continuous process of social change, and its processes began to be used in the 80s of the last century. Globalization represents a new trend of change in society, economy and technology. The process of globalization causes positive and negative effects. This paper deals with the positive and negative consequences of globalization and how they affect Croatia. The Republic of Croatia is a relatively young country affected by the war, which made it even more difficult for Croatia to cope with the phenomenon of globalization. It is obvious that globalization in the Republic of Croatia has been increasing over the years. One of the main goals of the foreign policy of the Republic of Croatia was to join the European Union. The paper mentions the research of the Swiss Confederation, which conducted a survey measured at the world level, where Croatia ranks 25th in the globalization index. According to this research, Croatia achieved the best result in social globalization, which takes into account indicators of the spread of ideas, information, etc., and achieved the worst result in political globalization, which takes into account indicators of political integration into international politics.
