Further injunctions prescribe that the Jews shall lock themselves up in their houses while church processions are marching through the streets; that in each city they shall possess no more than one synagogue; that, "in order to be marked off from the Christians," they shall wear a peculiarly shaped hat, with a horn-like shield (cornutum pileum), and that any Jew showing himself on the street without this headgear shall be subject to punishment, in accordance with the custom of the country.
The Christians are forbidden, under penalty of excommunication, to invite Jews to a meal, or to eat and drink with them, or dance and make merry with them at weddings and other celebrations. The Christians are barred from buying meat and other eatables from Jews, since the sellers might treacherously put poison in them.
These prohibitions are followed by the ancient canonical enactments forbidding the Jews to keep Christian servants, nursery-maids, and wet-nurses, and barring them from collecting customs duties and exercising any other public function. A Jew living unlawfully with a Christian woman is liable to imprisonment and fine, while the woman is subject to a public whipping and to banishment from the town for all time.
The Church Council which held its sessions in Buda (Ofen), in Hungary, in 1279, was attended by the highest ecclesiastic dignitaries of Poland. This Council ratified the clause concerning the "Jewish sign," supplementing it by the following details: The Jews of both sexes shall be obliged to wear a ring of red cloth sewed on to their upper garment, on the left side of the chest. The Jew appearing on the street without this sign shall be accounted a vagrant, and no Christian shall have the right to do business with him. A similar sign, only of saffron color, is prescribed for "Saracens and Ishmaelites," i. e. for Mohammedans. The law barring Jews from the collection of customs and the discharge of other public functions is extended by the Synod of Buda to the "sectarians," to the Christians of the Greek Orthodox persuasion.
In this manner the condition of the Jews of Poland in the thirteenth century was determined by two factors operating in different directions: the temporal powers, actuated by economic considerations, accorded the Jews the elementary rights of citizenship, while the ecclesiastic powers, prompted by religious intolerance, endeavored to exclude the Jews from civil life. As long as patriarchal conditions of life prevailed, and Catholicism in Poland had not yet assumed complete control over the country, the policy of the Church was powerless to inflict serious damage upon the Jews. They lived in safety, under the protection of the Polish princes, and, except for the German immigrants, managed to get along peaceably with the Christian population. But the clerical party was looking out for the future, taking assiduous care that "the new plantation on the soil of Christianity" should develop along the lines of the older plantations, and was scattering the seeds of religious hatred in the patient expectation of a plentiful harvest.
3. Rise of Polish Jewry under Casimir the Great
The Jewish emigration from Western Europe assumed especially large proportions in the first part of the fourteenth century. The butcheries perpetrated by the hordes of Rindfleisch and Armleder, and the massacres accompanying the Black Death, forced a large number of German Jews to seek shelter in Poland, which was then undergoing the process of unification and rejuvenation. In 1319, King Vladislav[28] Lokietek[29] laid the foundation for the political unity of Poland by abolishing the former feudal divisions, and his famous son Casimir the Great (1333-1370) was indefatigable in his endeavors to raise the level of civil and economic life in his united realm. Casimir the Great founded new cities and fortified old ones, promoted commerce and industry, and protected, with equal solicitude, the interests of all classes, not excluding those of the peasants. He was styled the "peasant king," and the popular commendation of his efforts in the upbuilding of the cities was crystallized in the saying that Casimir the Great "found a Poland of wood and left behind him a Poland of stone."
A ruler of this type could not but welcome the useful industrial activity of the Jews with the liveliest satisfaction. He was anxious to bring them in close contact with the Christian population on the common ground of peaceful labor and mutual helpfulness. He was equally quick to appreciate the advantages which the none too flourishing royal exchequer might derive from the experience of Jewish capitalists. Such must have been the motives which actuated Casimir when, in the second year of his reign (1344), he ratified, in Cracow, the charter which Boleslav of Kalish had granted to the Jews of Great Poland, and which he now extended in its operation to all the provinces of the kingdom.
