1895 was also the year when Iorga began his collaboration with the Iași-based academic and political agitator A. C. Cuza, making his earliest steps in antisemitic politics, founding with him a group known as the Universal ()and Romanian Antisemitic Alliance. In 1897, the year when he was elected a corresponding member of the Academy, Iorga traveled back to Italy and spent time researching more documents in the Austro-Hungarian Kingdom of Croatia-Slavonia, at Dubrovnik. He also oversaw the publication of the 10th Hurmuzachi volume, grouping diplomatic reports authored by Kingdom of Prussia diplomats in the two Danubian Principalities (covering the interval between 1703 and 1844). After spending most of 1898 on researching various subjects and presenting the results as reports for the Academy, Iorga was in Transylvania, the largely Romanian-inhabited subregion of Austria-Hungary. Concentrating his efforts on the city archives of Bistrița, Brașov and Sibiu, he made a major breakthrough by establishing that "Stolnic" Cantacuzino, a 17th-century man of letters and political intriguer, was the real author of an unsigned Wallachian chronicle that had for long been used as a historical source. He published several new books in 1899: "Manuscrise din biblioteci străine" ("Manuscripts from Foreign Libraries", 2 vols.), "Documente românești din arhivele Bistriței" ("Romanian Documents from the Bistrița Archives") and a French-language book on the Crusades, titled "Notes et extraits pour servir à l'histoire des croisades" ("Notes and Excerpts Covering the History of the Crusades", 2 vols.). Xenopol proposed his pupil for a Romanian Academy membership, to replace the suicidal Odobescu, but his proposition could not gather support.
