As the rabbis were required to face a new reality, that of Judaism without a Temple (to serve as the location for sacrifice and study) and Judea without autonomy, there was a flurry of legal discourse, and the old system of oral scholarship could not be maintained. It is during this period that rabbinic discourse began to be recorded in writing. The theory that the destruction of the Temple and subsequent upheaval led to the committing of Oral Torah into writing was first explained in the Epistle of Sherira Gaon and often repeated.
