Atamanshchina

Atamanshchina (Russian: атаманщина), otamanshchyna (Ukrainian: Отаманщина), or atamanism is a political situation during the Russian Civil War in Ukraine and in some parts of Russia with absent or weak central power, some areas were ruled by warlords, typically Cossack atamans. In Ukraine, these atamans showed lack of subordination towards the Second Hetmanate and later towards the Directorate of Ukraine.

Over time the term acquired the generic meaning of the decentralized rule of warlords.
