He returned to Wallachia in 1858, after the Crimean War had led to a drastic decrease in Russian influence (allowing for radicals to regin their country), and took an archaeological study trip. He included the results of his investigations in "Buciumul" and its successor "Trompeta Carpaţilor" (he began editing the latter in 1865). During the period, Bolliac also engaged in activism in favor of Wallachia's union with Moldavia, a goal reached under Alexandru Ioan Cuza. He later became a notorious antisemite, rejected the idea of naturalization for the Jews, and engaged in a polemic over this issue (and that of his version of Romanticism in general) with "Junimea"'s Titu Maiorescu.
