After the fall of Constantinople to the Crusaders, Greek nationalism accentuated. Niketas Choniates insisted on using the name "Hellenes", stressing the outrages of the "Latins" against the "Hellenes" in the Peloponnese and how the Alfeios River might carry the news to the barbarians in Sicily, the Normans. Nikephoros Blemmydes referred to the Byzantine emperors as Hellenes, and Theodore Alanias wrote in a letter to his brother that "the homeland may have been captured, but Hellas still exists within every wise man". The second Emperor of Nicaea, John III Doukas Vatatzes, wrote in a letter to Pope Gregory IX about the wisdom that "rains upon the Hellenic nation". He maintained that the transfer of the imperial authority from Rome to Constantinople was national and not geographic, and therefore did not belong to the Latins occupying Constantinople: Constantine's heritage was passed on to the Hellenes, so he argued, and they alone were its inheritors and successors. His son, Theodore II Laskaris, was eager to project the name of the Greeks with true nationalistic zeal. He made it a point that "the Hellenic race looms over all other languages" and that "every kind of philosophy and form of knowledge is a discovery of Hellenes […]. What do you, O Italian, have to display?"
