Bavarian Geographer in the context of "Moravians (tribe)"

"Polish tribes" is a term used sometimes to describe the tribes of West Slavic Lechites that lived from around the mid-6th century in the territories that became Polish with the creation of the Polish state by the Piast dynasty. The territory on which they lived became a part of the first Polish state created by duke Mieszko I and expanded at the end of the 10th century, enlarged further by conquests of king Bolesław I at the beginning of the 11th century.

In about 850 AD a list of peoples was written down by the Bavarian Geographer. Absent on the list are Lechitic-speaking Polans, Pomeranians and Masovians, who became known later and were written about by Nestor the Chronicler in his Primary Chronicle (11th/12th century).

The Buzhans were a tribal union of Early Slavs, which supposedly formed the East Slavs in southern Russia and the Volga region. They are mentioned as Buzhane in the Primary Chronicle. Several localities in Russia are claimed to be connected to the Buzhans, such as Sredniy Buzhan in Orenburg Oblast, and Buzhan and the Buzan River in Astrakhan Oblast.

Some theories say that the name of the tribes could be connected to Western Bug, in Ukraine, where they chose to settle down. According to the Bavarian Geographer, the Buzhans had 230 "cities" (fortresses). Some historians believe that the Buzhans and the Volhynians used to be called the Dulebes.
