Chronica Slavorum

The Chronica Sclavorum or Chronicle of the Slavs is a medieval chronicle which recounts the pre-Christian culture and religion of the Polabian Slavs, written by Helmold (c. 1120 – after 1177), a Saxon priest and historian. It describes events related to northwest Slavic tribes known as the Wends up to 1171.

History
It is a continuation of Adam of Bremen's Deeds of Bishops of the Hamburg Church and was in turn continued by Arnold of Lübeck's Chronica Slavorum.
