This paper includes an analysis of the economic and financial markets of the emerging countries of the European Union. The evolution of these markets is captured primarily in the context of the phenomena of globalization and deglobalization, but also in view of the economic, social and political conjunctures that these countries have experienced during the twenty years of transition from border markets to economies integrated with the European market. The study includes a descriptive analysis applied to the selected markets over a period of twenty years, based on the selected methodology. Analyzing on a long-term the evolution of the markets of Romania, Hungary, Poland and Greece through a comparative approach, the paper highlights similarities and differences in the developments of the Emerging European markets, as well as the degree of reaction to the major events that had an impact on the economic and financial environment of the European Union.
