Gamaliel II became Johanan ben Zakkai's successor, and rendered immense service in the strengthening and reintegration of Judaism, which had been deprived of its former basis by the destruction of the Second Temple and by the entire loss of its political autonomy. He put an end to the division which had arisen between the spiritual leaders of Judaism by the separation of the scribes into the two schools called respectively after Hillel and Shammai, and took care to enforce his own authority as the president of the chief legal assembly of Judaism with energy and often with severity. He did this, as he himself said, not for his own honor nor for that of his family, but in order that disunion should not prevail in Israel.
