Hungary proper, the autonomy of the Transylvanian counties was limited, because the voivodes restricted the development of their self-governing bodies. The general assemblies of the Transylvanian counties disappeared in the middle of the 14th century. Instead, the voivodes or their deputies held general assemblies for all noblemen from all the counties of the province. The first recorded general meeting of the "nobles of the realm of Transylvania" was held in Keresztes at Torda (now Cristiş in Romania) on 8 June 1288. The assembly authorized the vice-voivode, Ladislaus Borsa, to assist the representative of Peter Monoszló, Bishop of Transylvania, in taking possession of three villages of a noble family to secure the payment of a fine. The administration of justice remained the principal task of such meetings, but the noblemen who attended the assemblies also regularly discussed other subjects, including the collection of the tithe or custom duties. Initially, all noblemen were entitled to be present, but from the 15th century, the counties sent delegates to the assemblies. The general assembly of the Székelys could be convoked by the Count of the Székelys, or by the captain of Udvarhelyszék. The internal issues of the Saxons communities were initially regulated by the assemblies of the Saxon seats and districts. From 1486, the Count of the Saxons presided over the annual general assemblies of the entire community, which consisted of the highest-ranking officials of the seats and districts and elected delegates. The monarchs or on their behalf the voivodes could also convoke the representatives of all privileged groups of Transylvania to meet at a joint assembly. Andrew III of Hungary was the first king to hold such an assembly for the representatives of the Transylvanian noblemen, Saxons, Székelys and Romanians in early 1291. According to Andrew's charter mentioning the meeting, the king ordered the return of two domains to Ugrin Csák after those who attended the general assembly testified that he had been their lawful owner. Union of the Three Nations Transylvania was regularly raided by Ottoman armies from the 1420s, forcing the monarchs and the local authorities to strengthen the defense of the province. At the initiative of Sigismund of Luxembourg, King of Hungary, the general assembly of the Transylvanian noblemen ordered in 1419 that one third of the noblemen and one tenth of the peasants were to take up arms in case of an Ottoman invasion against the Székely and Saxon
