 The Strassburg visit is also one of the early recorded instances of a monarch employing "Lăutari" for musical entertainment, with a repertoire of "patrium carmen" ("songs of the country").In 1664, following an especially bloody civil war between the Cantacuzino and Băleanu boyars, the throne of Wallachia was taken by a Radu Leon.This relatively unknown figure claimed to be Prince Leon's son, but was more likely a Greek commoner; his political rise is attributable to him being a favorite of Ahmed Köprülü, the Grand Vizier.
