The fact that there is a specific age marking the emergence of adulthood in the United States has been well documented. The starting point for the studies included in this special issue is the assumption that the same can be said for European countries. Thus, a comparison of characteristics of emerging adulthood between different European countries was performed. In this special issue, contributions of scholars from five different European countries are taken as representative of different regions: Spain, Italy, Finland, Germany, and the Czech Republic. The efforts of the research are twofold. The first is to look at how the traditional markers of adulthood have changed and how the concept of adulthood is seen in the different countries. The second is to highlight the influence that the entrance into the working world and romantic partnership have on emerging adults and to detect the impact of the timing of entering adulthood on identity achievement. The results are presented here as different pathways that emerging adults follow to reach the same goal of mature adulthood.
