The World Bank was conceived in 1944 for the reconstruction of the war-torn Europe, and today it is working in more than 100 developing countries. Over the past 70 years, major changes have taken place in the world economy. During this period, the World Bank, which is the world's largest development institution, has been working to help more than 100 developing and transition countries to adapt to these changes by offering them loans, knowledge and advice, and reducing poverty and increasing common progress. Today, it is one of the world's largest sources of funding and development assistance. The World Bank is often criticized by environmental organizations and opponents of globalization policy. It is anticipated that too many projects are being financed such as dam construction or pipelines that have bad consequences for the environment and the local population. On the other hand, the World Bank is a source of financial and technical assistance to developing countries around the world, and its programs, projects and investments in all kinds of economic branches of a particular country are of great importance. The purpose of this paper is to demonstrate the benefits Croatia can have in the World Bank Group membership. We are acquainted with the goals, organizational structure, members, activities, partners and World Bank projects as well as projects and programs with the Republic of Croatia.
