How is Judaism spread?

Answer 1

Judaism spreads through spatial distribution.

Although anyone is welcome to learn and convert to Judaism, it is not a proselytizing religion, so followers are not sought after. The Jewish population mainly increases as Jewish children are born.

Answer 2

• Judaism itself:
  

As the Jewish communities spread and moved. This phenomenon was set in motion by the various expulsions and persecutions, which drove Jewish populations to settle in new places.

• Jewish influence:

As non-Jews came in contact with Jews, there was a degree of influence upon them. Ancient writers speak of large numbers of people in the Mediterranean area who had taken on various Jewish practices. It was these semi-converts who were especially likely to adopt Christianity.
As the new religion of Christianity spread, it taught those beliefs which it had adopted directly from Jewish sources, such as the prohibition of infanticide and human sacrifice.
