Page "Haggadah" Paragraph 3

According to Jewish tradition, the Haggadah was compiled during the Mishnaic and Talmudic periods, although the exact date is unknown.

It could not have been written earlier than the time of Rabbi Yehudah bar Elaay ( circa 170 CE ) who is the last tanna to be quoted therein.

According to most Talmudic commentaries Rav and Shmuel argued on the compilation of the Haggadah, and hence it had not been completed as of then.

Based on a Talmudic statement, it was completed by the time of Rav Nachman ( mentioned in Pesachim 116a ).

There is a dispute, however, to which Rav Nachman, the Talmud was referring: According to some commentators, this was Rav Nachman bar Yaakov ( circa 280 CE ), while others maintain this was Rav Nachman bar Yitzchak ( 360 CE ).
