The phrase Hetman of the Zaporizhian Cossacks encompasses various titles and positions of the Cossacks in the history of Ukraine.

"Hetman of His Royal Grace's Zaporizhian Host" was the formal title of the hetmans in the military service of the Polish–Lithuanian Commonwealth from 1572 to 1638, selected from the senior officers (starshyna) of the Registered Cossacks (Town Cossacks) in western, central and northern Ukraine; Hetman of the Zaporizhian Host refers to the head of state of the Cossack Hetmanate, the Ukrainian state of 1648–1764; Kish otamans of the Sich Cossacks in southern Ukraine from the 1620s to 1775, which until the late 17th century were also interchangeably called "hetmans"; Hetman of all Ukraine, a title claimed by Pavlo Skoropadsky for a few months in 1918.

With the creation of the Registered Cossacks units in 1572, their leading officers were officially referred to as "Senior of His Royal Grace's Zaporozhian Host". The Commonwealth created the Cossack Registry in competition with the formations of the unregistered Zaporizhian Cossacks (colloquially known as the "Zaporizhian Host") living in the Siches of southern Ukraine. According to the Encyclopedia of Ukraine, "The Commonwealth government officially named the registered Cossacks the Zaporozhian Army to underscore the fact that it considered the actual Zaporozhian Host a legal nonentity." For a brief period between the 1625 Treaty of Kurukove and the 1638 , the Registered Cossacks had the right to elect their own hetman, although he had to be approved by the king. After the 1637–1638 Cossack uprisings were suppressed, the post of hetman was abolished and replaced by a government commissioner. However, the Khmelnytsky Uprising of 1648 saw the combined forces of Registered (Town) and unregistered (Sich) Cossacks elect Bohdan Khmelnytsky as "Hetman of the Zaporizhian Host", without reference to "His Royal Grace"; this would become the title of the head of state of the Cossack Hetmanate ever since.

Background

The Registered Cossacks were formally established in 1572. Several Polish starostas such as Lanckoroński and Daszkiewicz, who also led their own Cossack formations in Polish service in the early 16th century, have been retroactively considered hetmans of the Registered Cossacks. According to Mykhailo Hrushevsky they were not really considered as hetmans, at least by their contemporaries. Among others such starostas were Karpo Maslo from Cherkasy, Yatsko Bilous (Pereiaslav), Andrushko (Bratslav), and many others. Even Princes Konstanty Ostrogski and Bohdan Hlinski were conducting Cossack raids on Tatar uluses (districts).

The commanders of Zaporozhian Host units (the Kish), often considered as hetmans (and sometimes named as such in primary sources), in fact served the function since the 1620s known as Kish otaman, a term which by the end of the 17th century completely replaced "hetman".

From 1572 onwards, "hetman" was the unofficial title of commanders of the Registered Cossack Army of the Polish–Lithuanian Commonwealth, which officially called them starszy ("senior" or "elder"). From 1625, Registered Cossacks were allowed to elect their own hetmans, subject to approval by the king. However, after suppressing the 1637–1638 Cossack uprisings, the Registered Cossack hetmanship in the Commonwealth was abolished and replaced by a government commissioner.

From the 1648 Khmelnytsky Uprising onwards, Hetman of the Zaporizhian Host was the title of the head of the Ukrainian Cossack state, the Cossack Hetmanate. Cossack hetmans were elected by the Cossack Rada (an early form of democracy), had limited powers in peacetime, but broad powers in wartime, and acted as supreme military commanders and executive leaders (by issuing administrative decrees).

After the split of Ukrainian territory along the Dnieper River by the Commonwealth-Tsardom Treaty of Andrusovo (1667), there was an introduction of dual leadership for each bank, or for each Ukraine of Dnieper (left and right). After 1667, there existed two different Cossack Hetmanates with two Hetmans: the Right-bank hetman was called "Nakazny Hetman of His Royal Mercy of Zaporizhian Host", and the Left-bank one titled "Hetman of His Tsarist Mercy's Zaporizhian Host".

Eventually the official state powers of the Right-Bank Hetmanate were phased out around 1712, when the Commonwealth discontinued conformations or appointments of hetmans and colonels of Registered Cossacks, integrated them in the Commonwealth army, and abolished the ten remaining Regiments on the Right Bank.

The state powers of the Left-Bank Cossack Hetmans were gradually diminished in the 18th century, and finally abolished by Catherine II of Russia in 1764. On the other hand, the powers of the hetmans of the Zaporizhian Sich increased in the 18th century at the expense of the Sich Rada democracy, until its liquidation in 1775.

Cossack leaders (until 1648)

Starosta A starosta (administrator, literally "elder") governed a starostwo, subordinate to a voivode. Przecław Lanckoroński (Predslav Lyantskoronsky; 1506–1512, died 1531), not an actual hetman, he was a starosta of Khmilnyk. Although later historians have often retroactively identified him as the first or second "hetman" or "otaman" of the Cossacks in service of Poland, the Cossack registry would not be formally established until 1572, and he has faced historiographic competition from Dashkevych and Vyshnevetsky as the "first". Ostap Dashkevych (1506–1536), not an actual hetman, he was a starosta in charge of a defense force approved by the Sejm near Cherkasy. Dashkevych offered to create a defense force on the banks of the Lower Dnieper, an important step towards the establishment of the Registered Cossacks in 1572. For similar reasons as Lanckoroński and Vyshnevetsky, he has therefore sometimes been retroactively considered the first or second hetman or otaman of the Cossacks. Dmytro Vyshnevetsky (1550–1564), not an actual hetman, he was a starosta of Cherkasy and Kaniv, who established a Cossack garrison at Khortytsia Castle in the 1550s.Hrushevsky, M. Illustrated History of Ukraine. "BAO". Donetsk, 2003. His characterisation as the "first Cossack hetman" (championed by Mykhailo Hrushevsky amongst others) has been challenged; it enjoys some, but not universal support amongst historians.
