The Lithuanian Grand Dukes typically selected submonarchs from their families or loyal subjects to assist controlling the [[Grand Duchy of Lithuania|Grand Duchy]]. However, the Grand Dukes remained superior.

* [[Vytenis]] (superior) and [[Gediminas]]
* [[Gediminas]] (superior) and an unknown duke of [[Trakai]], presumably Gediminas's son.
* [[Algirdas]] (superior) and [[Kęstutis]]
* [[Jogaila]] (superior) and [[Kęstutis]]

A slightly different system developed for a brief period after [[Vytautas]] became Grand Duke, where nominally Vytautas ruled together with [[Jogaila]], who took the title of ''{{lang|lt|aukščiausiasis kunigaikštis}}'' (Supreme Duke), but he has not once used the title to take any action, and in general the powers invested in the title were not clearly stated in any documents, besides the [[Pact of Horodlo]], which guaranteed that Jogaila would have to approve the selection of a Lithuanian Grand Duke. The title was not used by any other king of Poland after Jogaila.

* [[Vytautas]] (Grand Duke) and [[Jogaila]] (Supreme Duke)
* [[Švitrigaila]] (Grand Duke) and [[Jogaila]] (Supreme Duke) for a brief period, until [[Lithuanian Civil War (1431–1435)|Švitrigaila declared war on Poland]]
* [[Sigismund I of Lithuania]] (Grand Duke) and [[Jogaila]] (Supreme Duke) until Jogaila's death.
