The paper discusses the emergence of Slovenian maritime education after World War II and the importance of training Slovenian sailors in military and mercantile schools in different countries in the past. Special emphasis will be given to the presentation of the situation, time, circumstances and reasons for establishment of the Slovenian merchant maritime Academies, the predecessor of today's maritime school in Semedela near Koper, 1.3.1947. The emphasis will be on the Slovenian maritime and fishing education as well as beginning of education and employment of competent sailors, since this became crucial for the process in which Slovenian shipping was established. The need for the establishment of Maritime schools in our land was revealed shortly after Charles VI. declared freedom of navigation in the Adriatic in 1717. Bourgeoisie in Trieste and Rijeka that in the mercantilist era strove to increase import and export through our cities, demanded from the authorities that navigation is entrusted to skilled captains and officers. Thus, it became increasingly necessary to train a new generation of sailors, who would be able to sail and safely guide ships at sea. The growing specialization of trade also required schooled captains. In view of such requirements the establishment of maritime schools became necessary. Not only boys from coastal cities and surrounding areas, but also those from other regions of Slovenian ethnic territory enrolled in Maritime schools. Upon the establishment of the maritime school in 1947, the newspaper “Slovenski Jadran” wrote and summed up the essence of this paper: "So the former pupil became a student at the Slovenian maritime school. He came into the emancipated Slovenian coastal town from Kranjec’s Prekmurje, Prežih’s Carinthia, wine-growing Styria, black Trbovlje districts, sunny Bela Krajina, hospitable Lower Carniola and seemingly introverted Upper Carniola, from the land of cheerful people of karst and from all parts of Slovenia."
