In 1939, as the Guard's campaign of retribution had degenerated into terrorism, Iorga used the Senate tribune to address the issue and demand measures to curb the violence. He was absent for part of the year, again lecturing in Paris. Steadily publishing new volumes of "Istoria românilor", he also completed work on several other books: in 1938, "Întru apărarea graniței de Apus" ("For the Defense of the Western Frontier"), "Cugetare și faptă germană" ("German Thought and Action"), "Hotare și spații naționale" ("National Borders and Spaces"); in 1939 "Istoria Bucureștilor" ("History of Bucharest"), "Discursuri parlamentare" ("Parliamentary Addresses"), "Istoria universală văzută prin literatură" ("World History as Seen through Literature"), "Naționaliști și frontiere" ("Nationalists and Frontiers"), "Stări sufletești și războaie" ("Spiritual States and Wars"), "Toate poeziile lui N. Iorga" ("N. Iorga's Complete Poetry") and two new volumes of "Memorii". Also in 1938, Iorga inaugurated the open-air theater of Vălenii de Munte with one of his own dramatic texts, "Răzbunarea pământului" ("The Earth's Revenge"). The total number of titles he presented for publishing in 1939 is 45, including a play about Christina of Sweden ("Regele Cristina", "King Cname="ivliv">Iova, p. liv</ref> and an anti-war cycle of poems. Some of his Anglophile essays were printed by Mihail Fărcășanu in "Rumanian Quarterly", which sought to preserve Anglo–Romanian cooperation.
