Prejudice against Jews in the Roman Empire was formalized in 438, when the "Code of Theodosius II" established Christianity as the only legal religion in the Roman Empire. The Justinian Code a century later stripped Jews of many of their rights, and Church councils throughout the 6th and 7th century, including the Council of Orleans, further enforced anti-Jewish provisions. These restrictions began as early as 305, when, in Elvira, (now Granada), a Spanish town in Andalucia, the first known laws of any church council against Jews appeared. Christian women were forbidden to marry Jews unless the Jew first converted to Catholicism. Jews were forbidden to extend hospitality to Catholics. Jews could not keep Catholic Christian concubines and were forbidden to bless the fields of Catholics. In 589, in Catholic Iberia, the Third Council of Toledo ordered that children born of marriage between Jews and Catholic be baptized by force. By the Twelfth Council of Toledo (681) a policy of forced conversion of all Jews was initiated (Liber Judicum, II.2 as given in Roth). Thousands fled, and thousands of others converted to Roman Catholicism.
