The aim of article is to analyze the importance of migration in EU cooperation with the Kingdom of Morocco. Although population flows in the Mediterranean region are a constant phenomenon, their nature and intensity have changed. The specific nature of this region as an area of many disparities makes it a ‘problematic space’ of enormous importance for the entire planet. The complexity of changes in the region may in future lead to mass migration, which no country or organization will be able to cope with on its own. Two hypotheses were verified in order to achieve the research objective. The first assumes that the European model of migration management in the Mediterranean region is causing a change in the functioning of Arab societies, as exemplified by Morocco. The second hypothesis assumes that the intensification of EU cooperation with the Kingdom in the field of migration is a manifestation of external Europeanisation, which is undergoing gradual institutionalization. In the study, both the traditional theoretical perspective of subject analysis (E. Lee’s push-pull theory) and the new generation of migration theories (I. Wallerstein’s center-periphery system theory) proved helpful. Theoretical triangulation was supported by the process of combining methods (quantitative and qualitative). The quantitative strategy is manifested in the use of statistical techniques, while the qualitative strategy is evident in numerous references to the statements of people involved in decision-making regarding the matter. However, factor analysis was crucial for identifying the main variables determining the parties to change the way of cooperation in the field of migration. The study provided the basis for three conclusions. Firstly, in view of the growing threats affecting the Mediterranean, EU cooperation with Morocco on migration management is taking on new importance for the security and stability of the entire area. Secondly, the process of Europeanisation that has been taking place in Morocco since decolonization has led to the evolution and a high degree of convergence with the Western model of migration policy implementation in that country. Thirdly, we are witnessing the development of a 'Euro-Mediterranean migration policy,' whose central country ensuring its effectiveness will be Morocco.
