Khmelnytsky Uprising in the context of "Deluge (history)"

The Pereiaslav Agreement or Pereyaslav Agreement (Ukrainian: Переяславська рада, romanized: Pereiaslavska Rada, lit. 'Pereiaslav Council', Russian: Переяславская рада) was an official meeting that convened for a ceremonial pledge of allegiance by Zaporozhian Cossacks to Russian tsar Alexis (r. 1645–1676) in the town of Pereiaslav in central Ukraine, in January 1654. The ceremony took place concurrently with ongoing negotiations that started on the initiative of Hetman Bohdan Khmelnytsky to address the issue of the Cossack Hetmanate with the ongoing Khmelnytsky Uprising against the Polish–Lithuanian Commonwealth and which concluded the Treaty of Pereiaslav (also known as the March Articles). The treaty itself was finalized in Moscow in April 1654 (in March according to the Julian calendar).

Khmelnytsky secured the military protection of the Tsardom of Russia in exchange for allegiance to the tsar. An oath of allegiance to the Russian monarch from the leadership of the Cossack Hetmanate was taken, shortly thereafter followed by other officials, the clergy and the inhabitants of the Hetmanate swearing allegiance. The exact nature of the relationship stipulated by the agreement between the Hetmanate and Russia is a matter of scholarly controversy. The council of Pereiaslav was followed by an exchange of official documents: the March Articles (from the Cossack Hetmanate) and the tsar's declaration (from Russia).

Ukrainian nationalism (Ukrainian: Український націоналізм, romanized: Ukrainskyi natsionalizm, pronounced [ʊkrɐˈjinʲsʲkɪj nɐts⁽ʲ⁾ionɐˈl⁽ʲ⁾izm]) is the promotion of the unity of Ukrainians as a people and the promotion of the identity of Ukraine as a nation state. The origins of modern Ukrainian nationalism emerge during the Cossack uprising against the Polish–Lithuanian Commonwealth led by Bohdan Khmelnytsky in the mid-17th century. Ukrainian nationalism draws upon a single national identity of culture, ethnicity, geographic location, language, politics (or the government), religion, traditions and belief in a shared singular history.

Hetman is a political title from Central and Eastern Europe, historically assigned to military commanders (comparable to a field marshal or imperial marshal in the Holy Roman Empire). First used by the Czechs in Bohemia in the 15th century, it was the title of the second-highest military commander after the king in the Crown of the Kingdom of Poland and the Grand Duchy of Lithuania from the 16th to 18th centuries. Hetman was also the title of the head of the Cossack state in Ukraine after the Khmelnytsky Uprising of 1648. Throughout much of the history of Romania and Moldavia, hetmans were the second-highest army rank. In the modern Czech Republic, the title is used for regional governors.

Zynoviy Bohdan Mykhailovych Khmelnytsky of the Abdank coat of arms (1595 – 6 August 1657) was a Ruthenian nobleman and military commander of Zaporozhian Cossacks as Hetman of the Zaporozhian Host, which was then under the suzerainty of the Polish–Lithuanian Commonwealth. He led the Cossacks to victory in a successful uprising against the Commonwealth and its magnates (1648–1654) that resulted in the creation of an independent Cossack state in Ukraine.

In 1648–1649, the Cossacks under Khmelnytskyi's leadership massacred tens of thousands of Poles and Jews, with more handed over as yasir (slaves) to his Crimean Tatar allies, one of the most traumatic events in Polish and Jewish history. Under his rule of the newly-established Cossack state, the massacres continued until at least 1652. In 1654, Khmelnytsky concluded the Treaty of Pereiaslav with the Russian Tsar and allied the Cossack Hetmanate with Tsardom of Russia, thus placing Ukraine under Russian protection.

The Cossack Hetmanate (Ukrainian: Гетьма́нщина, romanized: Hetmanshchyna; see other names), officially the Zaporozhian Host (Ruthenian: Войско Zапорожскоε; Ukrainian: Військо Запорозьке, romanized: Viisko Zaporozke; Latin: Exercitus Zaporoviensis), was a stratocratic Zaporozhian Cossack state established by Registered Cossacks in Dnieper Ukraine. Its territory was located mostly in region of Central Ukraine, as well as in parts of Belarus and southwestern Russia, and at different points it also incorporated the territories of Zaporozhian Sich to the south. The Hetmanate existed between 1649 and 1764, although its administrative-judicial system persisted until 1781. In different periods it was a vassal of the Polish–Lithuanian Commonwealth, Ottoman Empire and Russian Empire.

The Hetmanate was founded in the eastern territories of the Polish–Lithuanian Commonwealth by the Treaty of Zboriv, signed on August 18, 1649 by Bohdan Khmelnytsky (Hetman of the Zaporizhian Host) and Adam Kysil (representing Crown Forces), as a result of Khmelnytsky Uprising. Establishment of vassal relations with the Tsardom of Russia in the Treaty of Pereiaslav of 1654 is considered a benchmark of the Cossack Hetmanate in Soviet, Ukrainian, and Russian historiography. The second Pereiaslav Council in 1659 restricted the independence of the Hetmanate, and from the Russian side there were attempts to declare agreements reached with Yurii Khmelnytsky in 1659 as nothing more than the "former Bohdan's agreements" of 1654. The 1667 Treaty of Andrusovo, conducted without any representation from the Cossack Hetmanate, established the borders between the Polish and Russian states, dividing the Hetmanate in half along the Dnieper and putting the Zaporozhian Sich under a formal joint Russian-Polish administration.

John III Sobieski (Polish: Jan III Sobieski (Polish pronunciation: [ˈjan ˈtʂɛt͡ɕi sɔˈbʲɛskʲi]); Lithuanian: Jonas III Sobieskis (Lithuanian pronunciation: ['joːnäs so'bʲɛskis]); Latin: Ioannes III Sobiscius (Latin pronunciation: [joˈannɛs soˈbiʃiʊs]) 17 August 1629 – 17 June 1696) was King of Poland and Grand Duke of Lithuania from 1674 until his death in 1696.

Born into Polish nobility, Sobieski was educated at the Jagiellonian University and toured Europe in his youth. As a soldier and later commander, he fought in the Khmelnytsky Uprising, the Russo-Polish War and during the Swedish invasion known as the Deluge. Sobieski demonstrated his military prowess during the war against the Ottoman Empire and established himself as a leading figure in Poland and Lithuania. In 1674, he was elected monarch of the Polish–Lithuanian Commonwealth following the sudden and unexpected death of King Michael.

The Poltava Regiment (Ukrainian: Полтавський полк) was one of ten territorial-administrative subdivisions of the Cossack Hetmanate. The regiment's capital was the city of Poltava, now in Poltava Oblast of central Ukraine.

The Poltava Regiment was founded in 1648 during the Khmelnytsky Uprising. Following the signing of the Treaty of Zboriv in 1649 it consisted of 19 sotnias, and had 2970 registered cossacks. In 1775, the regiment was officially abolished, and its territory was reformed into the Little Russia Governorate.

The Polish Golden Age (Polish: Złoty Wiek Polski [ˈzwɔ.tɘ ˈvjɛk ˈpɔl.ski] ) was the Renaissance period in the Kingdom of Poland and subsequently in the Polish–Lithuanian Commonwealth, which started in the late 15th century. Historians argue that the Polish Golden Age ended by the mid-17th century, when Poland was ravaged by the Khmelnytsky Uprising (1648–57) and by the Swedish and Russian invasion. During its Golden Age, the Commonwealth became one of the largest kingdoms of Europe and at its peak stretched from modern-day Estonia in the north to Moldavia in the south and from Moscow in the east to Brandenburg in the west.

In the 16th century the Polish–Lithuanian Commonwealth grew to 1 million km, with a population of 11 million. It prospered from its enormous grain, wood, salt, and cloth trade with Western Europe via the Baltic Sea ports of Gdańsk, Elbląg, Riga, Memel, and Königsberg. The Commonwealth's major cities also included Poznań, Kraków, Warsaw, Lwów, Wilno, Toruń, and, for a time, Kyiv and Smolensk. The Commonwealth army was able to defend the realm from foreign invasion, and also participated in aggressive campaigns against Poland's neighbors. As voluntary Polonization followed in unified territories, the Polish language became the lingua franca of Central and Eastern Europe.
