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.
Ukrainian nobility from Galicia The shliakhta (Ukrainian: шля́хта , Polish: "szlachta" ) were a noble class of ethnic Ukrainians in what is now western Ukraine, that enjoyed certain legal and social privileges. Estimates of their numbers vary. According to one estimate, by the mid-nineteenth century there were approximately 32,000 Ukrainian nobles in the western Ukrainian territory of Galicia, over 25% of whom lived in 21 villages near the town of Sambir. They comprised less than 2% of the ethnic Ukrainian population. Other estimates place the number of nobles at 67,000 people at the end of the 18th century and 260,000 by the end of the nineteenth century, or approximately 6% of the ethnic Ukrainian population. The nobles tended to live in compact settlements either in villages populated mostly by nobles or in particular areas of larger villages.
