Iorga embarked on a longer journey during 1930: again lecturing in Paris during January, he left for Genoa and, from there, traveled to the United States, visiting some 20 cities, being greeted by the Romanian-American community and meeting with President Herbert Hoover. He was also an honored guest of Case Western Reserve University, where he delivered a lecture in English. Returning to attend the London International Congress of History, Iorga was also made a "honoris causa" doctor by the University of Oxford (with a reception speech likening him to both Livy and Pliny the Elder). That year, he also set up the "Casa Romena" institute in Venice. His new works included "America și românii din America" ("Romania and the Romanians of America") and "Priveliști elvețiene" ("Swiss Landscapes"), alongside the plays "Sfântul Francisc" ("Saint Francis") and "Fiul cel pierdut" ("The Lost Son"). In 1931–1932, he was made a "honoris causa" doctor by four other universities (the University of Paris, La Sapienza, Stefan Batory, Comenius), was admitted into both "Accademia dei Lincei" and the "Accademia degli Arcadi", and published over 40 new titles per year.
