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.
Rulers recorded in historical sources.
Of the dukes who signed the peace treaty, only four are mentioned in other written sources: Mindaugas, who went on to become the Grand Duke of Lithuania and was crowned as King of Lithuania in 1253, Vykintas, leader of anti-Mindaugas coalition during the civil war in 1248–1251, Bikšys and Ligeikis, both identified as Mindaugas relatives and nobles, mentioned in a document, dated 1260 and sometimes considered a forgery.
