Rav Yehudah [b. Yechezkel]

Rav Yehudah studied under Rav until he died and eventually went to study under Shmuel, with whom he had a more complicated relationship. After Shmuel died, he established an academy in Pumbedita, which eventually became the leading center of the Babylonian community. He further consolidated the independence of the Jewish center in Babylonia.
