What tribe was Hoshea Ben Eilah, the last king of Malchus Yisrael, from?
Seder Hadoros says he was from Reuven, but in the same sentence it says that in his days Zechus Avos stopped. The thing is that this Gemara in Shabbos 55a is actually about the Navi Hoshea Ben Be'iri.
That mistake appears to have come from misreading the Shalshelles Hakabballa (in newer copies of the Seder Hadoros available on Otzar Hachochma you can see that this was his source, and its clearly a misread. The Navi Hoshea was actually from Shevet Reuven also as it says in Bereishis Rabbah 84:19 and elsewhere):
Does anyone have a source as to what Shevet he actually was from?
