Before 21 Lithuanian dukes signed a peace treaty with Galicia–Volhynia, what is an example of the war-related functions the group who made up the majority of the military-economic staff of the state performed?
Leičiai Leičiai (singular: leitis) were a distinct social group of the Lithuanian society in the early Grand Duchy of Lithuania subordinate to the Lithuanian ruler or the state itself. Leičiai were native to the Lietuva Land and formed the core of the Lithuanian society in the pre-state era and during the establishment of the state. Leičiai made up the majority of the military-economic staff of the state: they enforced state authority in the periphery, protected state borders, and performed various other war-related functions, such as breeding riding horses. By the 15th and 16th centuries, leičiai were in decline, already losing some of their functions and prestige, and they disappeared as a social class after the implementation of the Wallach Reform.
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.
