ostrogorsky repaid in more than one way the hospitality he met with in his new country; he created a new generation of yugoslav byzantinists, broadened the horizons of yugoslav historians by the example of his personal research, and provided for them closer contacts with the world scholarly community. under his guidance the belgrade institute became, along with munich, paris, and dumbarton oaks, a leading center of research in the field of byzantinology. ostrogorsky remained faithful to belgrade to the very end, although over the years suggestions were made that he take up residence in an american or soviet center of byzantine studies.
