Mogilev in the context of "Nikolay Krestinsky"

The Metropolis of Kiev, Galicia and all Rus' was a metropolis of the Ecumenical Patriarchate of Constantinople in the Eastern Orthodox Church that was erected in 1620. The dioceses (eparchies) included the Eparchy of Kiev itself, along with the eparchies of Lutsk, Lviv, Mahilioŭ, Przemyśl, Polatsk, and Chernihiv. The dioceses lay in the territory of the Polish–Lithuanian Commonwealth, which was at war with the Tsardom of Moscow for much of the 17th century. Around 1686, the Kiev and Chernihiv dioceses became Moscow-controlled territory. At the same time, the metropolis transferred from the ecclesiastical jurisdiction of the Ecumenical Patriarchate of Constantinople to the Patriarchate of Moscow in 1686. It is a matter of dispute as to whether this de facto transfer was also de jure or canonical.

Lew Sapieha (Belarusian: Леў Сапега; Lithuanian: Leonas Sapiega; 4 April 1557 – 7 July 1633) was a nobleman and statesman of the Polish–Lithuanian Commonwealth. He became Great Secretary of the Grand Duchy of Lithuania in 1580, Great Clerk of the Grand Duchy in 1581, Crown Chancellor in 1585, Grand Chancellor from 1589 until 1623, Voivode of Vilnius in 1621, Great Lithuanian Hetman in 1623 and governor of Slonim, Brest and Mogilev.

Sapieha is considered as a great political figure of the Commonwealth. A rich and powerful magnate, he was known for his wisdom as a statesman, lawyer and military commander, he was one of the greatest leaders of the Grand Duchy of Lithuania at the times of the Duchy's highest cultural flourishing. He was of Ruthenian (Belarusian) ethnicity. Modern Belarusian sources interpret his Ruthenian heritage as Belarusian.

The Pripet Marshes, or Pripyat Marshes (Belarusian: Прыпяцкія балоты, romanized: Prypiackija baloty), also known as Pinsk Marshes (Belarusian: Пінскія балоты, romanized: Pinskiya baloty), the Polesie Marshes, and the Rokitno Marshes, are a vast natural region of wetlands in Polesia, along the forested basin of the Pripyat River and its tributaries from Brest to the west, Mogilev in the northeast, and Kyiv to the southeast. Most of the region is in Belarus, and part is in Ukraine. The Pripet Marshes are the largest wetland area in Europe.

The history of the Jews in Belarus begins as early as the 8th century. Jews lived in all parts of the lands of modern Belarus. In 1897, the Jewish population of Belarus reached 910,900, or 14.2% of the total population. Following the Polish-Soviet War (1919-1920), under the terms of the Treaty of Riga, Belarus was split into Eastern Belorussia (under Soviet occupation) and Western Belorussia (under Polish occupation), and causing 350,000-450,000 of the Jews to be governed by Poland. Prior to World War II, Jews were the third largest ethnic group in Belarus and comprised more than 40% of the urban population. The population of cities such as Minsk, Pinsk, Mogilev, Babruysk, Vitebsk, and Gomel was more than 50% Jewish. In 1926 and 1939 there were between 375,000 and 407,000 Jews in Belarus (Eastern Belorussia) or 6.7-8.2% of the total population. Following the Soviet annexation of Eastern Poland in 1939, including Western Belorussia, Belarus would again have 1,175,000 Jews within its borders, including 275,000 Jews from Poland, Ukraine, and elsewhere. It is estimated that up to 800,000 of 900,000 — up to 90% of the Jews of Belarus —were killed during the Holocaust. According to the 2019 Belarusian census, there were 13,705 self-identifying Jews in Belarus, of which most are of Ashkenazi origin. However, the Israeli embassy in Belarus claims to know about 30-50 thousand Belarusians with Jewish descent (as of 2017).
