„The scientific work of Nicolae Iorga who for almost half a century was the outstanding representative of Romanian historical science, is marked by vast proportions and by the variety of the objects of his researches. Possessing a many-sided spirit which blossomed by a thorough training acquired in the French and German universities, Nicolae Iorga concentrated from the very first his enormous capacity for work on the vast domain of world history ranging from ancient to modern and contemporary history which he handled with a modern and original scientific method and with innovating insight. But of all the fields of research he tackled during his long and fruitful activity, he granted special importance to the problems of mediaeval history to which he brought new and original contributions enriching it with publications of sources, special studies and vast syntheses.”
