The Polans (Polish: Polanie; Latin: Polani, Polanos), also known as Polanians or Western Polans (Polish: Polanie Zachodni; Latin: Polani Occidentis), are a West Slavic and Lechitic tribe, inhabiting the Warta River basin of the contemporary Greater Poland region starting in the 6th century. They are one of the main tribes in Central Europe and are closely related to the Vistulans, Masovians, Czechs and Slovaks. According to Zygmunt Gloger, their name was derived from the word "pole" meaning "field", thus denoting them as "men of the fields".
