Rovenki
Rovenki lies in the steppe country of the Aidar basin. Once called Osinovy Rovenyok, it was a Cossack sloboda on the southern frontier of the Russian state; a church of Saint Nicholas was begun there in 1669. During Kondraty Bulavin's revolt in the early eighteenth century, the settlement supported the rebels and was destroyed after their defeat. A decree of 1709 ordered the resettlement of Cossacks of the Ostrogozhsk regiment toward the Aidar and Rovenki, part of the government's effort to reorganize this frontier.
