Henry of Livonia

The Chronicle of Henry of Livonia (Latvian: Indriķa hronika, Latin: Heinrici Cronicon Lyvoniae, Estonian: Henriku Liivimaa kroonika) is a historic document describing the history of Latvia and Estonia from 1180 to 1227. Apart from the few references in the Russian Primary Chronicle compiled in Kiev in the twelfth century, it is the oldest known written document about the history of these countries. For many episodes in the early stages of Christianizing the peoples of the Eastern Baltic, Henry's chronicle is the major surviving evidence aside of The Livonian Rhymed Chronicle and The chronicle of Novgorod, 1016-1471.
