All cities and towns with a Jewish population had their separate Kahal boards. Their size corresponded roughly to that of the given community. In large centers the membership of the Kahal board amounted to forty; in smaller towns it was limited to ten. The members of the Kahal were elected annually during the intermediate days of Passover. As a rule the election proceeded according to a double-graded system. Several electors (_borerim_), their number varying from nine to five, were appointed by lot from among the members of all synagogues, and these electors, after taking a solemn oath, chose the Kahal elders. The elders were divided into groups. Two of these, the _rashim_ and _tubim_ (the "heads" and "optimates"), stood at the head of the administration, and were in charge of the general affairs of the community. They were followed by the _dayyanim_, or judges, and the _gabbaim_, or directors, who managed the synagogues as well as the educational and charitable institutions. The _rashim_ and _tubim_ formed the nucleus of the Kahal, seven of them making a quorum; in the smaller communities they were practically identical with the Kahal board. The sphere of the Kahal's activity was very large. Within the area allotted to it the Kahal collected and turned over to the exchequer the state taxes, arranged the assessment of imposts, both of a general and a special character, took charge of the synagogues, the Talmudic academies, the cemeteries, and other communal institutions. The Kahal executed title-deeds on real estate, regulated the instruction of the young, organized the affairs appertaining to charity and to commerce and handicrafts, and with the help of the _dayyanim_ and the rabbi settled disputes between the members of the community. As for the rabbi, while exercising unrestricted authority in religious affairs, he was in all else dependent on the Kahal board, which invited him to his post for a definite term. Only great authorities, far-famed on account of their Talmudic erudition, were able to assert their influence in all departments of communal life.
