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

• Žvelgaitis (Svelgates) – earliest known duke. In 1205, he attacked Riga and was killed in the battle, led by ruler of Semigallia, Vester.

• Daugirutis (Dangerutis, Dangeruthe) – Livonians imprisoned this Lithuanian duke in 1213, where he killed himself.

• Stekšys (Stakys, Steksė) – another powerful duke, killed in 1214 near Lielvārde.

• Father of Mindaugas – several sources mention that he was a powerful duke, but do not give his name. 16th century geanelogies gave him the name of Ryngold or Ringaudas.

• The following Lithuanian dukes signed a peace treaty with rulers of Halych-Volhynia in 1219:

• *Duke elders
