By 1648, in the close proximity of today's Nikopol, Mykytyn Sich was built, renowned for the fact that it was here that Bohdan Khmelnytsky was elected as the Hetman of Ukraine, and it was here that the rebellion against the Polish–Lithuanian Commonwealth started. Until 1775, the time of the Sich sacking, it was called "Mykytyn Rih", "Mykytyn Pereviz", or simply "Mykytyne". The name "rih" (Ukrainian for horn) was given because the locality rose at a place reminiscing a peninsula, as it was almost surrounded by the Dnieper river (see Kryvyi Rih). Mykytyne was a town of the Kodak Palanka, an administrative division of the Zaporizhian Sich. Later it was renamed into Slovianske and then Nikopol.
