Huna I) was a rabbi of the 2nd century CE (fifth generation of tannaim) and Babylonian Exilarch, allegedly descending from King David.
The Seder Olam Zutta refers to him as "Anani", both names being a derivative of "Hananiah".
Once Judah haNasi asked R. Hiyya whether he could be obligated (if the Temple had been standing) to offer the "Korban Nasi" (leader's sacrifice) over sins he might have, a question that basically meant whether he had the status of a king or not.
R. Hiyya replied: "You have your rival in Babylon", referring to Huna Kamma.
[6] The Hebrew word for "rival" (צרה) is also used to describe either of two wives of a single man,[7] indicating that the "nasi" and "exilarch" are positions of equal stature, and thus neither of the two was a sole leader who might be obligated in the Korban Nasi.
