Final answer:
Jews became the main moneylenders in Medieval Europe due to social and economic factors such as Christian prohibitions and limited occupational opportunities for Jews.
Step-by-step explanation:
In Medieval Europe, Jews became the main moneylenders due to a combination of social and economic factors. Christians were prohibited by the Church from charging interest on loans, so Jews stepped in, taking advantage of this opportunity. Additionally, Jews were often excluded from other professions, so money lending became one of the few occupations available to them. They also developed networks and connections across different regions, which helped them establish a reputation as trustworthy lenders.
