Before the end of that year, the Iorgas were in the Austro-Hungarian city of Budapest. While there, the historian set up tight contacts with Romanian intellectuals who originated from Transylvania and who, in the wake of the "Transylvanian Memorandum" affair, supported ethnic nationalism while objecting to the intermediary Cisleithanian (Hungarian Crown) rule and the threat of Magyarization. Interested in recovering the Romanian contributions to Transylvanian history, in particular Michael the Brave's precursory role in Romanian unionism, Iorga spent his time reviewing, copying and translating Hungarian-language historical texts with much assistance from his wife. During the 300th commemoration of Prince Michael's death, which ethnic Romanian students transformed into a rally against Austro-Hungarian educational restrictions, Iorga addressed the crowds and was openly greeted by the protest's leaders, poet Octavian Goga and Orthodox priest Ioan Lupaș. In 1902, he published new tracts on Transylvanian or Wallachian topics: "Legăturile Principatelor române cu Ardealul" ("The Romanian Principalities' Links with Transylvania"), "Sate și preoți din Ardeal" ("Priests and Villages of Transylvania"), "Despre Cantacuzini" ("On the Cantacuzinos"), "Istoriile domnilor Țării Românești" ("The Histories of Wallachian Princes").
