 Bălcescu's most important work is "Românii supt Mihai-Voievod Viteazul" ("Romanians under the Rule of Michael the Brave"), which he wrote in exile in 1849 - first published posthumously by Alexandru Odobescu in 1860.The volume is history of Michael's campaigns, as the first moment when Wallachia, Transylvania, and Moldavia, came under a single, albeit brief rule.They show Bălcescu's commitment to both radicalism and nationalism, his view oscillating between praise of Michael's gestures and criticism of his stance as a supporter of serfdom and privilege.
