"Petro Konashevych-Sahaidachny (Ukrainian: Петро Конашевич-Сагайдачний; Polish: Piotr Konaszewicz-Sahajdaczny; born about 1582 in Kulchytsi, today Sambir Raion – 20 April 1622 in Kyiv) was a Ukrainian Cossack political and civic leader, Hetman of Zaporozhian Cossacks from 1616 to 1622, a military leader of Polish–Lithuanian Commonwealth both on land and sea. While being a hetman, he transformed the Cossack Host from an irregular military formation into a regular army. Under his tenure a greater common identity developed the Cossacks, the Orthodox clergy and peasants of Ukraine, which would ultimately be inherited as a modern national consciousness. His troops played a significant role in the Battle of Khotyn against the Turks in 1621 and Polish Prince Władysław's attempt to gain the throne of Russia in 1618." - (en.wikipedia.org 19.10.2023)
