Pereiaslav in the context of "Alta River"

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).

The Principality of Pereyaslavl (Ukrainian: Переяславське князівство; Russian: Переяславское княжество) was a regional principality of Kievan Rus' from the end of 9th century until 1323, based in the city of Pereyaslavl (now Pereiaslav) on the river Trubizh.

Poltava Governorate was an administrative-territorial unit (guberniya) of the Russian Empire. It was officially created in 1802 from the disbanded Little Russia Governorate and had its capital in Poltava.

Its borders encompassed the modern Poltava Oblast of Ukraine, in addition to Berestyn, Pereiaslav, Romny and Zolotonosha.

Boryspil Raion (Ukrainian: Бориспільський район, romanized: Boryspil's'kyi raion) is an administrative raion (district) in east-central Kyiv Oblast of Ukraine. Its administrative center is the city of Boryspil. Population: 203,154 (2022 estimate).

On 18 July 2020, as part of the administrative reform of Ukraine, the number of raions of Kyiv Oblast was reduced to seven, and the area of Boryspil Raion was significantly expanded. Two abolished raions, Pereiaslav-Khmelnytskyi and Yahotyn Raions, as well as the cities of Boryspil and Pereiaslav, which were previously incorporated as cities of oblast significance and did not belong to the raion, were merged into Boryspil Raion. The area of the raion before the reform was 146 square kilometres (56 sq mi). The January 2020 estimate of the raion population was 53,619 (2020 est.).

The Trubizh (Ukrainian: Трубі́ж, Russian: Трубе́ж) is a river entirely located in Ukraine, a left tributary of Dnieper. It falls into the Dnieper's Kaniv Reservoir (named after Kaniv). It is 113 kilometres (70 mi) long, and has a drainage basin of 4,700 square kilometres (1,800 sq mi).
