the Great reformed the Grand Duchy's army: instead of calling all men to arms, he created forces comprising professional warriors—bajorai ("nobles"; see the cognate "boyar"). As there were not enough nobles, Vytautas trained suitable men, relieving them of labor on the land and of other duties; for their military service to the Grand Duke, they were granted land that was worked by hired men (veldams). The newly formed noble families generally took up, as their family names, the Lithuanian pagan given names of their ennobled ancestors; this was the case with the Goštautai, Radvilos, Astikai, Kęsgailos and others. These families were granted their coats of arms under the Union of Horodlo (1413). In 1506, King Sigismund I the Old confirmed the position of the Lithuanian Council of Lords in state politics and limited entry into the nobility. Privileges Specific rights of the szlachta included: The right to hold outright ownership of land (Allod)—not as a fief, conditional upon service to the liege Lord, but absolutely in perpetuity unless sold. The szlachta had a monopoly on land. Peasants did not own land. See Polish landed gentry (Ziemiaństwo). The right to join in political and military assemblies of the regional nobility. The right to form independent administrative councils for their locality. The right to cast a vote for Polish Kings. The right to travel freely anywhere in the old Commonwealth of the Polish and Lithuanian nobility; or outside it, as foreign policy dictated. The right to demand information from Crown offices. The right to spiritual semi-independence from the clergy. The right to interdict, in suitable ways, the passage of foreigners and townsmen through their territories. The right of priority over the courts of the peasantry. Special rights in Polish courts, including freedom from arbitrary arrest and freedom from corporal punishment. The right to sell their military or administrative services. Heraldic rights. The right to receive higher pay when entitled in the "Levée en masse" (mobilization of the szlachta for defence of the nation). Educational rights The right of importing duty-free goods often. The exclusive right to enter the clergy until the time of the three partitions of Poland. The right to try their peasants for major offences (reduced to minor offences only, after the 1760s). Significant legislative changes in the status of the szlachta, as defined by Robert Bideleux and Ian Jeffries, consist of its 1374 exemption from the land tax, a
