France.
Judaism was not spread in Ancient Rome. The Romans frowned on Jewish practice, often restricting it or forbidding it.
Judaism did not spread through proselytization for the majority of its existence and therefore spread only within families and communities of Hebrews, Israelites, or Judeans (the same people at different times).
Judaism spread fast so equals yes
The way the question is written implies agency. Most of Judaism's spread was based on necessary migrations of Jews from other countries. Judaism spread by way of people moving, not populations converting. Jews spread throughout the Roman Empire, expanded out through much of Europe and also spread to the New World and Australia, before the mass return of Jews to Israel.
Judaism does not recognize or encourage missionaries for the purpose of proselytizing.

JudaismGenerally speaking, throughout history Judaism hasn't really spread per se. Rather it has survived and grown naturally through childbirth. This is due to the fact that Judaism doesn't proselytize and the number of converts throughout history has been minimal. Keep in mind that during most of history and in most places, converting to Judaism was considered a capital offense, punishable by death or losing all your possessions. Generally speaking most Jews are descendents of Jews. Only in recent years has conversion to Judaism picked up a bit, relatively to previous generations.ChristianityChristianity has spread through proselytization, movement of Christians to different places in the world, forcible conversion, and debate. Once Christianity became the official religion of Rome, it also wielded political power, leading to many more conversions.
