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.
Imperial Knight The Free Imperial knights (German: "Reichsritter" Latin: "Eques imperii" ) were free nobles of the Holy Roman Empire, whose direct overlord was the Emperor. They were the remnants of the medieval free nobility ("edelfrei") and the ministeriales. What distinguished them from other knights, who were vassals of a higher lord, was the fact that they had been granted Imperial immediacy, and as such were the equals in most respects to the other individuals or entities, such as the secular and ecclesiastical territorial rulers of the Empire (margraves, dukes, princes, counts, archbishops, bishops, abbots, etc.) and the Free Imperial cities, that also enjoyed Imperial immediacy. However, unlike all of those, the Imperial knights did not possess the status of Estates ("Stände") of the Empire, and therefore were not represented, individually or collectively, in the Imperial Diet.
