Principality of Polotsk in the context of "Polotsk"

Belarus, officially the Republic of Belarus, is a landlocked country in Eastern Europe. It is bordered by Russia to the east and northeast, Ukraine to the south, Poland to the west, and Lithuania and Latvia to the northwest. Belarus spans an area of 207,600 square kilometres (80,200 sq mi) with a population of 9.1 million. The country has a hemiboreal climate and is administratively divided into six regions. Minsk is the capital and largest city; it is administered separately as a city with special status.

For most of the medieval period, the lands of modern-day Belarus was ruled by independent city-states such as the Principality of Polotsk. Around 1300 these lands came fully under the Grand Duchy of Lithuania and subsequently by the Polish–Lithuanian Commonwealth; this period lasted for 500 years until the 1792-1795 partitions of Poland-Lithuania placed Belarus within the Russian Empire for the first time. In the aftermath of the Russian Revolution in 1917, different states arose competing for legitimacy amid the Civil War, ultimately ending in the rise of the Byelorussian SSR, which became a founding constituent republic of the Soviet Union in 1922. After the Polish-Soviet War (1918–1921), Belarus lost almost half of its territory to Poland. Much of the borders of Belarus took their modern shape in 1939, when some lands of the Second Polish Republic were reintegrated into it after the Soviet invasion of Poland, and were finalized after World War II. During World War II, military operations devastated Belarus, which lost about a quarter of its population and half of its economic resources. In 1945, the Byelorussian SSR became a founding member of the United Nations, along with the Soviet Union. The republic was home to a widespread and diverse anti-Nazi insurgent movement which dominated politics until well into the 1970s, overseeing Belarus's transformation from an agrarian to an industrial economy.

The Mongol Empire invaded and conquered much of the Kievan Rus' in the mid-13th century, sacking numerous cities such as Ryazan, Yaroslavl, Pereyaslavl and Vladimir, including the largest: Kiev (50,000 inhabitants) and Chernigov (30,000 inhabitants). The siege of Kiev in 1240 by the Mongols is generally held to mark the end of the state of Kievan Rus', which had already been undergoing fragmentation. Many other principalities and urban centres in the northwest and southwest escaped complete destruction or suffered little to no damage from the Mongol invasion, including Galicia–Volhynia, Pskov, Smolensk, Polotsk, Vitebsk, and probably Rostov and Uglich.

The Mongol campaign was heralded by the Battle of the Kalka River on 31 May 1223, which resulted in a Mongol victory over the forces of several principalities as well as the remnants of the Cumans under Köten. The Mongols retreated, having gathered their intelligence, which was the purpose of the reconnaissance-in-force. A full-scale invasion by Batu Khan followed, with most of Kievan Rus' overrun in 1236–1238. The Mongols captured Kiev in 1240 and moved west into Hungary and Poland. The heavy losses suffered by the Mongols during the invasion period significantly weakened subsequent campaigns, preventing the ruin of the Holy Roman Empire and more western countries.

The Varangians (/vəˈrændʒiənz/ və-RAN-jee-ənz; Old Norse: Væringjar; Medieval Greek: Βάραγγοι, romanized: Várangoi; Old East Slavic: варяже, romanized: varyazhe, or варяги, varyagi) were Viking warriors, traders and settlers, mostly from present-day Sweden, who settled in the territories of present-day Belarus, Russia and Ukraine from the 8th and 9th centuries and established the state of Kievan Rus' as well as the principalities of Polotsk and Turov. They also formed the Byzantine Varangian Guard.

According to the 12th-century Primary Chronicle, a group of Varangians known as the Rus' settled in Novgorod in 862 under the leadership of Rurik. Before Rurik, the Rus' might have ruled an earlier hypothetical polity known as the Rus' Khaganate. Rurik's relative Oleg conquered Kiev in 882 and established the state of Kievan Rus', which was later ruled by Rurik's descendants.

Minsk (Belarusian: Мінск, pronounced [mʲinsk] ; Russian: Минск, pronounced [mʲinsk]) is the capital and largest city of Belarus, located on the Svislach and the now subterranean Nyamiha rivers. As the capital, Minsk has a special administrative status in Belarus and is the administrative centre of Minsk region and Minsk district. As of 2024, it has a population of about two million, making Minsk the 11th-most populous city in Europe. Minsk is one of the administrative capitals of the Commonwealth of Independent States (CIS) and the Eurasian Economic Union (EAEU).

First mentioned in 1067, Minsk became the capital of the Principality of Minsk, an appanage of the Principality of Polotsk, before being annexed by the Grand Duchy of Lithuania in 1242. It received town privileges in 1499. From 1569, it was the capital of Minsk Voivodeship, an administrative division of the Polish–Lithuanian Commonwealth. It was part of the territories annexed by the Russian Empire in 1793, as a consequence of the Second Partition of Poland. From 1919 to 1991, after the Russian Revolution, Minsk was the capital of the Byelorussian Soviet Socialist Republic, which became a republic of the Soviet Union in 1922. Following the dissolution of the Soviet Union, Minsk became the capital of the newly independent Republic of Belarus.

The Principality of Minsk was an appanage principality of the Principality of Polotsk and centered on the city of Minsk (today in Belarus). It existed from its founding in 1101 until it was nominally annexed by the Grand Duchy of Lithuania in 1242, and then fell under de facto annexation in 1326.

Rogvolod (Russian: Рогволод; Belarusian: Рагвалод, romanized: Rahvalod; c. 920 – 978) was the first chronicled prince of Polotsk. He reigned until 978, when he and his two sons were killed by Vladimir the Great, then the prince of Novgorod, who took his daughter Rogneda as a wife.
