The Kahal of each city extended its authority to the adjacent settlements and villages which did not possess autonomous organizations of their own. Moreover, the Kahals of the large centers kept under their jurisdiction the minor Kahals, or prikahalki,67 as they were officially called, of the towns and townlets of their district, as far as the apportionment of taxes and the judicial authority were concerned. This gave rise to the "Kahal boroughs," or gheliloth (singular, galil). Often disputes arose between the Kahal boroughs as to the boundaries of their districts, the contested minor communities submitting now to this, now to the other, "belligerent." On the whole, however, the moderate centralization of self-government benefited the Jewish population, since it introduced order and discipline into the Kahal hierarchy, and enabled it to defend the civil and national interests of Judaism more effectively.
The capstone of this Kahal organization were the so-called Waads,68 the conferences or assemblies of rabbis and Kahal leaders. These conferences received their original impetus from the rabbis and judges. The rabbinical law courts, officially endowed with extensive powers, were guided in their decisions by the legislation embodied in the Bible and the Talmud, which made full provision for all questions of religious, civil, and domestic life as well as for all possible infractions of the law. Yet it was but natural that even in this extensive system of law disputed points should arise for which the competency of a single rabbi did not suffice. Moreover there were cases in which the litigants appealed from the decision of one rabbinical court to another, more authoritative, court. Finally lawsuits would occasionally arise between groups of the population, between one community and another, or between a private person and a Kahal board. For such emergencies conferences of rabbis and elders would be called from time to time as the highest court of appeal.
Beginning with the middle of the sixteenth century these conferences met at the time of the great fairs, when large numbers of people congregated from various places, and litigants arrived in connection with their business affairs. The chief meeting-place was the Lublin fair, owing to the fact that Lublin was the residence of the father of Polish rabbinism, the above-mentioned Rabbi Shalom Shakhna, who was officially recognized as the "senior rabbi" of Little Poland. As far back as in the reign of Sigismund I. the "Jewish doctors," or rabbis, met there for the purpose of settling civil disputes "according to their law." In the latter part of the sixteenth century these conferences of rabbis and communal leaders, assembling in connection with the Lublin fairs, became more frequent, and led in a short time to the organization of regular, periodic conventions, which were attended by representatives from the principal Jewish communities of the whole of Poland.
The activity of these conferences, or conventions, passed, by gradual expansion, from the judicial sphere into that of administration and legislation. At these conventions laws were adopted determining the order of Kahal elections, fixing the competency of the rabbis and judges, granting permits for publishing books, and so forth. Occasionally these assemblies of Jewish notables endorsed by their authority the enactments of the Polish Government. Thus, in 1580, the representatives of the Polish-Jewish communities, who assembled in Lublin, gave their solemn sanction to the well-known Polish law barring the Jews of the Crown, of Poland proper, from farming state taxes and other public revenues, in view of the fact that "certain people, thirsting for gain and wealth, to be obtained from extensive leases, might thereby expose the community to great danger."
Towards the end of the sixteenth century the fair conferences received a firmer organization. They were attended by the rabbis and Kahal representatives of the following provinces: Great Poland (the leading community being that of Posen), Little Poland (Cracow and Lublin), Red Russia (Lemberg), Volhynia (Ostrog and Kremenetz), and Lithuania (Brest and Grodno). Originally the name of the assembly varied with the number of provinces represented in it, and it was designated as the Council of the Three, or the Four, or the Five, Lands. Subsequently, when Lithuania withdrew from the Polish Kahal organization, establishing a federation of its own, and the four provinces of the Crown69 began to send their delegates regularly to these conferences, the name of the assembly was ultimately fixed as "the Council of the Four Lands" (Waad Arba Aratzoth).
The "Council" was made up of several leading rabbis of Poland,70 and of one delegate for each of the principal Kahals selected from among their elders – the number of the conferees altogether amounting to about thirty. They met periodically, once or twice a year, in Lublin and Yaroslav (Galicia) alternately. As a rule, the Council assembled in Lublin in early spring, between Purim and Passover, and in Yaroslav at the end of the summer, before the high holidays.
The representatives of the Four Lands – says a well-known annalist of the first half of the seventeenth century71– reminded one of the Sanhedrin, which in ancient days assembled in the Chamber of Hewn Stones (lishkath ha-gazith) of the temple. They dispensed justice to all the Jews of the Polish realm, issued preventive measures and obligatory enactments (takkanoth), and imposed penalties as they saw fit. All the difficult cases were brought before their court. To facilitate matters the delegates of the Four Lands appointed [a special commission of] so-called "provincial judges" (dayyane medinoth) to settle disputes concerning property, while they themselves [in plenary session] examined criminal cases, matters appertaining to hazaka (priority of possession) and other difficult points of law.
The Council of the Four Lands was the guardian of Jewish civil interests in Poland. It sent its shtadlans72 to the residential city of Warsaw73 and other meeting-places of the Polish Diets for the purpose of securing from the king and his dignitaries the ratification of the ancient Jewish privileges, which had been violated by the local authorities, or of forestalling contemplated restrictive laws and increased fiscal burdens for the Jewish population.
But the main energy of the Waad was directed towards the regulation of the inner life of the Jews. The statute of 1607, framed, at the instance of the Waad, by Joshua Falk Cohen, Rabbi of Lublin, is typical of this solicitude. The following rules are prescribed for the purpose of fostering piety and commercial integrity among the Jewish people: to pay special attention to the observance of the dietary laws, to refrain from adopting the Christian form of dress; not to drink wine with Christians in the pot-houses, in order not to be classed among the disreputable members of the community; to watch over the chastity of Jewish women, particularly in the villages where the Jewish arendars74 with their families were isolated in the midst of the Christian population. In the same statute rules are also laid down tending to restrain the activities of Jewish usurers and to regulate money credit in general.
In 1623 the Kahals of Lithuania withdrew from the federation of the Four Lands, and established a provincial organization of their own, which was centralized in the convention of delegates from the three principal Kahals of Brest, Grodno, and Pinsk. Subsequently, in 1652 and 1691, the Kahals of Vilna and Slutzk were added. The Lithuanian assembly was generally designated as the "Council of the Principal Communities of the Province of Lithuania" (Waad Kehilloth Rashioth di-Medinath Lita). The organic statute, framed by the first Council, comprises many aspects of the social and spiritual life of the Jews. It lays down rules concerning the mutual relationship of the communities, the methods of apportioning the taxes among them, the relations with the outside world (such as the Polish Diets, the local authorities, the landed nobility, and the urban estates), the elections of the Kahals, and the question of popular education. The Lithuanian Waad met every three years in various cities of Lithuania, but in cases of emergency
