Final answer:
The Visigoths' conversion to Catholic Christianity marked an era of increased persecution of Jews, as they faced the choice between conversion and expulsion.
Step-by-step explanation:
The conversion of the Visigoths to Christianity had significant impacts on their relationship with Jewish people. When the Visigoths were Arian Christians, they generally tolerated non-Arian subjects. However, under the influence of Catholicism, the Visigoths' policies changed, and persecution of Jews became more prevalent. The Jewish community faced the ultimatum of conversion to Christianity or facing expulsion from the kingdom. This period highlights religious intolerance and the precarious position of Jewish communities during medieval times. Conversely, Jewish communities often found greater tolerance and opportunities in Muslim lands, such as in Al-Andalus, compared to Christian kingdoms where they faced systemic persecution.
