International financial institutions are most commonly founded so as to develop interstate exchanges. The most prominent organizations are International Monetary Fund and World Bank Group, both founded during World War II when many economies were destroyed and financial crisis started. They were developed to give financial help to then destroyed economies via various methods, and they even gave advice for further development. For these two organizations, we can say that they were the basis for further development of the international financial institutions. Each of them has its goas and ways of helping member countries which previously had to meet some requirements to enter the organization. Besides offering financial aid to member countries, these two organizations encourage the development of trade among members, private investments, help schooling system and other. IMF and World Bank have played an important role in Croatia, too since the first days of membership when Croatia was still shattered by the War of Independence. In the aftermath of war, these two organizations helped fiancially Croatia economy's foundation and development. With that, we can mention the period of Croatia’s entry to the European Union when their loans were also very helpful. Nowadays, the cooperation between Croatia and international financial institutions is continued by encouragement of different economy branches.
