Reply To: Most Jewish Communities=No Mesora

North African ( Moroccan) Jews were these since the first bayis. There were another bunch of Jews that came after the Spanish expulsion and thus there are two groups of Morrocan Jews, and as we know the RIF lived there who was student of ree Migash who was a student of Rav Hai gaon so you have it right there the Moroccan Jews have the strongest mesora in the Jewish nation on my opinion
