Tymofiy Khmelnytsky in the context of List of rulers of Moldavia

Yurii Khmelnytsky (Ruthenian: Юрый Хмелницкій / Юрий Хмелницкий / Юрій Хмелницкій; Ukrainian: Юрій Хмельницький, Polish: Jerzy Chmielnicki, Russian: Юрий Хмельницкий), monastic name Hedeon (1641 – 1685(?)), younger son of the famous Ukrainian Hetman Bohdan Khmelnytsky and brother of Tymofiy Khmelnytsky, was a Zaporozhian Cossack political and military leader. Although he spent half of his adult life as a monk and archimandrite, he also was Hetman of Ukraine on several occasions — in 1659-1660 and 1678–1681 and starost of Hadiach, becoming one of the most well-known Ukrainian politicians of the "Ruin" period for the Cossack Hetmanate.

The Battle of Batih (Ukrainian: Битва під Батогом, Polish: Bitwa pod Batohem; 1–2 June 1652) was fought between the Cossack Hetmanate and Crimean Khanate against the Polish–Lithuanian Commonwealth as a part of the Khmelnytskyi Uprising. Near the village of Batih in the Bratslav Regiment, a forces of the Zaporozhian Cossacks and Crimean Tatars under the command of Bohdan Khmelnytsky, Tymofiy Khmelnytsky, Ivan Zolotarenko, Ivan Sirko and Ivan Bohun attacked and completely defeated the Polish–Lithuanian forces under the command of Marcin Kalinowski, Zygmunt Przyjemski, Marek Sobieski, Marcin Czarniecki and Samuel Kalinowski, all of them were killed in action or taken captive. After the battle, the captured Polish–Lithuanian troops were brutally slain and beheaded by the Zaporozhian Cossacks and Crimean Tatars, as a revenge for the Battle of Berestechko.

During the battle, the forces of Cossack Hetmanate and Crimean Khanate destroyed many and one of the best Polish–Lithuanian military units. Although the Polish–Lithuanian Commonwealth managed to rebuild their army soon after the battle, the losses of the most experienced troops resulted in its temporary weakness. Defeat of the Crown Army contributed to the wars to come with the Tsardom of Muscovy and Swedish Empire, which in turn resulted into the Deluge.

The Battle of Berestechko (Ukrainian: Битва під Берестечком, Polish: Bitwa pod Beresteczkiem; 28 June – 10 July 1651) was fought between the Cossack Hetmanate and Crimean Khanate against the Polish–Lithuanian Commonwealth as a part of the Khmelnytsky Uprising. Near the site of the present-day city of Berestechko in Ukraine forces of the Zaporozhian Cossacks and Crimean Tatars under the command of Hetman Bohdan Khmelnytsky, Otaman Tymofiy Khmelnytsky, Colonels Ivan Bohun and Fylon Dzhalaliy with Khan İslâm III Giray and Tugay Bey, who was killed in the battle, were defeated by the Polish–Lithuanian Commonwealth's forces under the command of the Polish King John II Casimir, Prince Jeremi Wiśniowiecki, Hetmans Marcin Kalinowski and Stanisław Lanckoroński. The battle took place in the Volhynian Voivodeship on a hilly plain south of the Styr River. The Polish–Lithuanian camp was on the Styr River opposite Berestechko and faced south, towards the Zaporozhian Cossack positions about two kilometers away, with the right flank of the latter covered by the Pliashivka (Pliashova) River and the left flank by Crimean Tatars. It is considered to have been among the largest European land battles of the 17th century.
