Ion Heliade Rădulescu made extensive use of the Romantic nationalist focus on history, which he initially applied to his poetry. In this instance as well, the goal was to educate his public; he wrote: "Nothing is worthy of derision as much as someone taking pride in his parents and ancestors and nothing more worthy of praise than when the ancestors' great deeds serve as a model and an impulse for competition among descendants". The main historical figure in his poetry is the late 16th century Wallachian Prince Michael the Brave, the first one to rally Wallachia, Moldavia and Transylvania under a single rule: celebrated in Heliade's poem "O noapte pe ruinele Târgoviştii" ("A Night on the Ruins of Târgovişte"), he was to be the main character of a lengthy epic poem, "Mihaiada", of which only two sections, written in very different styles, were ever completed (in 1845 and 1859 respectively). Other historical poems also expanded on the ideal of a single Romanian state, while presenting the 1848 generation as a model for future Romanian politicians.
