The name Babruysk (as well as that of the Babruyka River) probably originates from the Belarusian word babyor (бабёр; 'beaver'), many of which used to inhabit the Berezina. However, beavers in the area had been almost eliminated by the end of the 19th century due to hunting and pollution. Babruysk is one of the oldest cities in Belarus. It was first mentioned in writing in the middle of the 14th century. Investigations by archaeologists revealed that in the 5th and 6th centuries there existed Slavic settlements up the river Biarezina from where Babruysk is currently located; findings of stone tools and weapons suggest that people have lived in the area since the Stone Age. During the reign of Vladimir I, Prince of Kiev, in place of modern-day Babruysk there was a village whose inhabitants were occupied with fishing and beaver trapping. This is where the name Babruysk originated. For many centuries Babruysk was part of the Polish–Lithuanian Commonwealth and was an important militarily fortified border post. In the 14th century a castle was built on one of the hills near the Berezina River.
