List of early Lithuanian dukes Early dukes of Lithuania (including Samogitia) reigned before Lithuanians were unified by Mindaugas into a state, the Grand Duchy of Lithuania. While the Palemonids legend provides genealogy from the 10th century, only few dukes were mentioned by contemporary historical sources. All of them were mentioned in written sources the 13th century. Data about them is extremely scarce and is usually limited to few brief sentences. The primary sources are the Chronicle of Henry of Livonia and Hypatian Codex.
