The bulava (Polish: buława, Ukrainian and Russian: булава) was a ceremonial mace or baton carried by a hetman, an officer of the highest military rank (a Field or Grand Hetman of Poland, the Polish-Lithuanian Commonwealth, and the Chief Otaman of Ukraine) or the military head of a Cossack state. In Slavic languages, a bulava is a mace or a club, in both the military and ceremonial senses.
Hetmans typically added an image of a bulava to their coats of arms.
Today the bulava appears in the rank insignia of a Marshal of Poland.
In period of Ukrainian People's Republic the General Staff of the Ukrainian Army was called the General Bulawa.
The bulava is also an official symbol of the President of Ukraine, being housed in Ukraine's Vernadsky National Library.
