A footnote cannot do justice to the vast literature on the subject of Christian–Jewish relations in the Middle Ages. In general, one can start from Chazan's, Robert overview, The Jews of Medieval Western Christendom, 1000–1500 (Cambridge: Cambridge University Press, 2006)Google Scholar; and Cohen, Mark, Under Crescent and Cross. The Jews in the Middle Ages (Princeton: Princeton University Press, 1994)Google Scholar, which explains the condition of Jews under Christian and Muslim rule, arguing their comparatively less stable position in the former case. Much has been done to make the sources of Jewish history widely accessible. Notable examples are Linder, Amnon, ed., The Jews in the Legal Sources of the Early Middle Ages (Detroit: Wayne State University Press, 1997)Google Scholar; Grayzel, Solomon, The Church and the Jews in the XIIIth Century, Vols. I (New York: Hermon Press, 1966)Google Scholar; and II (Detroit: Wayne State University Press, 1989); and the multi-volume Simonsohn, Shlomo, ed., The Jews in Sicily (Leiden: Brill, 1997-)Google Scholar. For the outset of the subsequent period, see Stow, Kenneth R., Catholic Thought and Papal Jewry Policy, 1555–1593 (New York: The Jewish Theological Seminary of America, 1977)Google Scholar. The relationship between ideas underpinning the canon law on the subject, broader economic, social, and political developments, and the analytical usefulness of the long period itself for assessing actual Christian–Jewish relations, has generated much debate. Cohen, Jeremy, The Friars and the Jews. The Evolution of Medieval Anti-Judaism (Ithaca: Cornell University Press, 1982)Google Scholar has shown the emergence of a polemical discourse, which contrasted the stylized, ahistorical Jew of Christian theology with contemporary Jews, found the latter deviant, and hence undermined the ancient assumption that Christians ought to tolerate the existence of Jews in their midst. Moore, Robert I., The Formation of a Persecuting Society (Malden, MA: Blackwell Publishing, 2007)Google Scholar argues for the high medieval transformation of European society from one in which persecution occasionally occurred, into one that functioned through persecution. Nirenberg, David, Communities of Violence. Persecution of Minorities in the Middle Ages (Princeton: Princeton University Press, 1996)Google Scholar finds the long period of little use, and argues that polemical discourses about Jews resulted in no forward thrust toward an ever more pronounced anti-Judaism. For multiple approaches to the subject of violence, see Abulafia, Anna Sapir, ed., Religious Violence between Christians and Jews (New York: Palgrave, 2002)CrossRefGoogle Scholar. There can be little doubt that the content of the law could be made to bear upon social life—however slowly and with however varied outcomes—through the concerted efforts of preachers, see Hughes, Diane Owen, “Distinguishing Signs: Ear-Rings, Jews and Franciscan Rhetoric in the Italian Renaissance City,” Past and Present 112 (1986): 3–59Google Scholar.

5. On the latter point, see also Langmuir, Gavin I., “Tanquam Servi:' The Change in Jewish Status in French Law about 1200,” in his Toward a Definition of Antisemitism (Berkeley: University of California Press, 1990), 167–94Google Scholar, which provides a broader overview of the problem than the title suggests; and Carpenter, Dwayne E., Alfonso X and the Jews: an Edition of and Commentary on Siete Partidas 7.24 “De los judíos” (Berkeley: University of California Press, 1986)Google Scholar. Langmuir's work also briefly presents the debate of the emergence, spread, and meaning of the notion of Jewish servitude, which has been central to debates on the subject: did the concept of the Jews' “servitude” and their place under royal authority (chamber serfdom or not) undermine their legal status more than it enhanced their security (by placing them directly under royal protection)? The latter part of the question can in turn be addressed in terms of both royal protection and royal violence (arbitrary taxation, expulsion). For further implications of the Jews' dependence on royal power see Nirenberg, Communities of Violence, ch. 2–4.

6. Some have argued that Western laws were largely inspired by Islamic law's treatment of dhimmīs populations, whereas others argued that the Islamic law on the subject had itself been influenced by Roman law, or that it had evolved from Mohammad's treatment of Jewish tribes in Arabia. See, respectively, Boisard, Marcel A., “On the Probable Influence of Islam on Western Public and International Law,” International Journal of Middle East Studies 11(4) (1980): 429–50Google Scholar, Coulson, Noel J., A History of Islamic Law (Edinburgh: At the University Press, 1964), 27Google Scholar and Ye'or, Bat, The Dhimmi.

Orakhelashvili, Alexander (Cheltenham, UK: Edward Elgar Publishing, 2011), 394–407Google Scholar. Clearly, some Christian legislation predated the emergence of Islam (intermarriage, slave ownership, sharing of meals), other was contemporaneous with it (exclusion from public office), and other, again, was pioneered in Islamic lands (distinguishing signs). For an overview of Muslims' place in the law, see Freidenreich, David, “Muslims in Western Canon Law, 1000–1500,” in Christian–Muslim Relations: A Bibliographical History, Vol. III, ed. Thomas, David and Mallett, Alex (Leiden: Brill, 2011), 41–68Google Scholar. The series itself aims at presenting work that is “written substantially about or against the other faith, or contains significant information or judgments that cast light on attitudes of one faith toward the other.” Ibid, viii. Brief presentations of the authors are followed by more detailed ones of their works' content, significance, extant manuscripts, editions, translations, and studies.

7. To the extent that any consensus concerning the actual condition of Christendom's Muslims as well as non-Christians at large has been achieved, it seems to award primacy to three factors: a given population's size (large Muslim communities in Iberia but small ones in Hungary, larger communities in Valencia than in the Ebro valley); that population's function within society (multifaceted as that of Iberian Jews or specialized as that of Jews in most of later medieval Europe); and its relationship to secular authorities (for example, Iberian Muslims were deemed indispensable in the thirteenth century, but were treated as disposable in contemporary Sicily). A nuanced view is not easily achieved, in part because one and the same body of evidence has been used to support contrasting positions. For nuanced views in the case of Iberia, see Nirenberg, Communities of Violence and Catlos, Brian, The Victors and the Vanquished. Christians and Muslims of Catalonia and Aragon, 1050–1300 (Cambridge: Cambridge University Press, 2004)CrossRefGoogle Scholar. For Sicily, see Abulafia, David, Mediterranean Encounters, Economic, Religious, Political, 1100–1550 (Aldershot: Ashgate, 2000)Google Scholar, especially #XII and XIII; and Abulafia, David, Frederick II. A Medieval Emperor (Oxford: Oxford University Press, 1988)Google Scholar. Overall, the literature on Muslim communities under Latin rule is both vast and fragmented. In general, see Powell, James, ed., Muslims under Latin Rule, 1100–1300 (Princeton: Princeton University Press, 1990)Google Scholar, which covers Iberia, Italy, and the Holy Land. In addition, for Iberia, see also Burns, Robert, Muslims, Christians, and Jews in the Crusader Kingdom of Valencia (Cambridge: Cambridge University Press, 1984)Google Scholar. For Hungary, see Berend, Nora, At the Gate of Christendom. Jews, Muslims and ‘Pagans’ in Medieval Hungary, c.1000–c.1300 (Cambridge: Cambridge University Press, 2001)Google Scholar. The richness of the literature on the Italian maritime cities can easily surprise the nonspecialist, but it hardly offers systematic treatments of the subject. See, for a discussion of the labels applied to non-Catholics, Balard, Michel, “Infidèles ou Comans? A propos des ‘Sarraceni’ de Caffa,” in La Storia dei Genovesi 8 (1988): 9–14Google Scholar. Highly original if not entirely convincing is the statistics-based approach to the subject of Ponomarev, A. L., “Territorija i naselenie genuezscoj Caffe po dannim buhgalterskoj knighi – massarii kaznachejstva za 1381–1382 gg [Territory and Population of Genoese Caffa According to Data from the Account Book – Massaria for the Treasury for 1381–1382],” in Prichernomorie v Srednie veka, Vol. 4 [The Black Sea Region in the Middle Ages], ed.

15. It is not my goal to deal with the origins of the law, the condition of non-Christians in the laws of secular rulers, or the degree to which daily life was made to conform to the canons. Nor does this article aim at comprehensive treatment of all laws on the subject. It excludes, for example, those on intermarriage and sexual relations, which were not discussed alongside the canons contained in X. 5.6, which are the subject of interest here. On marriage and sexual relations, see Brundage, James, “Intermarriage between Christians and Jews in Medieval Canon Law,” Jewish History 3(1) (1988): 25–40CrossRefGoogle Scholar, and Nirenberg, David, “Conversion, Sex, and Segregation: Jews and Christians in Medieval Spain,” The American Historical Review 107(4) (2002): 1065–93Google Scholar.

16. Using individual papal letters and counciliar canons as found in modern, critical editions is adequate only when studying the specific cases and contexts of the original documents. In all other cases, one must consult the texts used by medieval lawyers, which were often heavily edited, and hence varied considerably from their original, full-length versions. “The canonists molded the papal letters which they put into their collections to their taste. They shortened them, added sentences, changed words, and summarized passages.” Pennington, Kenneth, “The Making of a Decretal Collection: The Genesis of Compilatio Tertia,” in Pennington, Kenneth, Popes, Canonists, and Texts, 1150–1550 (Aldershot: Ashgate Variorum, 1993), #8, 83Google Scholar.

27. On the development of law concerning Jews in public office see Colorni, Gli ebrei nel sistema del diritto comune, 20–34 and Pakter, Medival Canon Law and the Jews, 221–47. Pakter, ididem, 240, n. 85 reproduces X. 5.6.18 and finds it to require the king to put Saracens and Jews who collect taxes “under Christian supervision,” ibidem, 241. I understand the canon differently, however, as the relevant section reads: “and if by chance he [the king] sells his revenues to Jews or to pagans, he ought then appoint a Christian not suspected of inflicting burdens upon clergymen and churches, through whom the Jews or Saracens may pursue the royal dues without injury to Christians” (“...et si forte reditus suos Iudaeis vendiderit vel paganis, Christianum tunc deputet de gravaminibus inferendis clericis et ecclesiis non suspectum, per quem Iudaei sive Sarraceni sine Christianorum iniuria iura regalia consequantur”). Pakter's reading of the canon leads him to see the papacy as relaxing this particular part of its Jewry legislation. I agree with Pakter that Jewish collectors must have been under Christian supervision at some level, but the point of the canon seems to be an altogether different one: cutting the physical/visible connection between the actual tax farmer (the non-Christian) and the taxpayers and hence removing the appearance of non-Christians as standing higher than Christians. Thus I find the policy not so much altered as adapted through a compromise that theoretically suited all three parties involved.

Non e bisogno dire che solo liheretici sieno excomunicati: ma etiam cogiudei non sidebbe havere domestica conversatione e maxime gligrossi et gliignoranti.” Tractato volgare del frate Antonino Arcivescovo di Firenze intitolato Defecerunt che insegna ai confessori diche chasi et in che modo debbe domandare colui che egli confessa (Florence: impressa per ser Lorenzo Margrani & Giovanni di Maganza, 1496), Cap. 135.

61. “Soli enim heretici sunt excommunicati, sed et cum aliis praecipue iudeis non debet haberi domestica conversatio et praecipue idiote.” Antoninus of Florence, Confessionale (Venice: Bartholomaeus Cremonensis, 1473)Google Scholar, Cap. 58 (the book is difficult to search despite the presence of a list of capitulae at the end). The same wording appears, among other editions, in Antoninus of Florence, Confessionale (Rome: In domo Francisci de Cinquinis, ca. 1477)Google Scholar, f50v; (Speier: Johann and Conrad Hist, ~1487), f60r; (Venice: Antonius de Strata, 1483), f49r; and (Strasbourg: Per Martin um Flach, 1492, 1496), f67v (the first of two folios numbered 67). Other editions vary slightly the wording, altering somewhat the meaning; therefore, “intimate contact” becomes “too much intimate contact:” “…non debet haberi nimis domestica conversatio et praecipue ydiote,” Antoninus of Florence, Confessionale (Cologne: Printer of the ‘Historia S. Albani' [Johann Guldenschaff or Conrad Winters, de Homborch?], 1472)Google Scholar, Cap. 23; and (Memmingen: Albrecht Kunne, 1483), f40r.

63. “La infidelidad delos paganos et hereticos o judios es muy grave pegado et lieva al infierno et solos los hereticos entre estos son descomulgados et no deve el hombre tener conversacion domestica con judios mayormente et mucho menos deve tener la tal conversacion los idiotas et los que no son letrados.” Antoninus of Florence, Summa de confession (Burgos: Fadrique de Basilea, 1499)Google Scholar, f99v.

68. Hostiensis begins by stating that Jews who refuse to accept the faith are subject to multiple burdens and starts from the issue of bequests. He does not allow bequests to the community of Jews, citing Cod. 1.9.1., but raises the question if one might be allowed to bequeath to individuals, referring to Azo and citing Dig. 34.5.20. Without elaborating any further, Hostiensis then cautions that this is not allowed to clergymen, even if the Jew is the clergyman's brother. Hostiensis, Summa, f236r.

69. “Item clericus iudeo, sarraceno, vel consanguineo suo aliquid in testamento non potest relinquere.” Renard, Trois sommes de pénitence, II:241. This treatment may have stemmed from an error, possibly authorial, for it seems to be found in all three extant manuscripts. As Panormitanus clearly states: “Also, note that this prohibition is only [valid] with regard to non-Catholics (non Catholicorum), not with regard to those that do not belong to one's family (extraneorum). Therefore, a clergyman can bequeath to a Catholic…However, if he dies intestate, not existing blood relatives, the church receives by succession.” Panormitanus, Lectura, V, f40r.
