In what area were the Leičiai native to during 1219 and 1295?
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.
Osraige Osraige, also known as Osraighe or Ossory (modern Irish: "Osraí" ), was a medieval Irish kingdom comprising most of present-day County Kilkenny and western County Laois. The home of the Osraige people, it existed from around the first century until the Norman invasion of Ireland in the 12th century. It was ruled by the Dál Birn dynasts, whose medieval descendants assumed the surname Mac Giolla Phádraig. The name survives in the Catholic Diocese of Ossory, established in the 5th century, which continues to use roughly the same borders.
