In 1921 and 1922, the Romanian scholar began lecturing abroad, most notably at the University of Paris, while setting up a Romanian School in the French capital and the "Accademia di Romania" of Rome. In 1921, when his 50th birthday was celebrated at a national level, Iorga published a large number of volumes, including a bibliographic study on the Wallachian uprising of 1821 and its leader Tudor Vladimirescu, an essay on political history ("Dezvoltarea așezămintelor politice", "The Development of Political Institutions"), "Secretul culturii franceze" ("The Secret of French Culture"), "Războiul nostru în note zilnice" ("Our War as Depicted in Daily Records") and the French-language "Les Latins de l'Orient" ("The Oriental Latins"). His interest in Vladimirescu and his historical role was also apparent in an eponymous play, published with a volume of Iorga's selected lyric poetry.
