According to Russian ethnologist Academician Shakhmatov's research on the origin of the Eastern Slavic nation, the distant ancestors of Belarusians can be traced back to the Vyajik who lived in the middle reaches of the Dnieper River in the 9th century, and the Latimitch and Dragovich who came from the west in the 6th and 7th centuries. In the 9th century, together with Russians and Ukrainians, they merged into the territory of Kiev Ross, and the Gullas tribe was formed by the combination of * * * *. Later, during the feudal separatist period, it got rid of the rule of Kiev Ross, merged into the Principality of Lithuania in the14th century, and then merged into Poland in 1569. In this process, some Lithuanians were absorbed and influenced by Poland and gradually formed an independent Belarusian tribe. At that time, the neighboring commune was responsible for the distribution of land and taxes. Pastures, forests, hunting areas and fishing grounds were all owned by the commune, and commune members helped each other economically. By the end of 18, Poland was divided up several times (1772, 1793, 1795), and Belarus was annexed by Russia. With the development of capitalism, the economic and cultural ties between local residents have become increasingly frequent and consolidated, and finally a modern country Belarus was formed in the19th century. The Soviet regime was founded in 19 17, occupied by Germany in 19 18, and the Belarusian Soviet Socialist Republic was founded in the beginning of 19 19. 19 19 ~ 1920 was occupied by the second Republic of Poland. 192 1 year, East Belarus resumed Soviet power, and 1922 joined the Soviet Union. 1939, western Belarus merged with Belarus.
