Dates: 1380 - 1380 (Dates are approximate. )
Hermann von Wartberge (died ca. 1380) was a chronicler of the Livonian Order. Born in Westphalia, Wartberge was a Catholic priest and author of the valuable Latin chronicle Chronicon Livoniale covering the history of the Livonian Crusade from 1196 to 1378. Wartberge used previous chronicles (Livonian Rhymed Chronicle and Chronicle of Henry of Livonia), archival documents, and personal experiences. As the narrative became more detailed around 1358, it is believed that Wartberge joined the Order around the time and began describing the events as an eyewitness. For example, in 1366 he was sent on a diplomatic mission to GdaÅ„sk (Danzig) and took part in numerous military campaigns against the pagan Grand Duchy of Lithuania. Wartberge provided extensive details on localities of the frequent raids and on construction of Livonian fortresses.
