How many kings did Hosea prophecy under?

Hosea prophesied during the reigns of several kings of Israel, specifically under Jeroboam II, and his prophecies span the final days of the Northern Kingdom. His ministry occurred during a time of political instability, witnessing the rule of at least five other kings: Zechariah, Shallum, Menahem, Pekahiah, and Pekah. Hosea's messages addressed both the moral decay and impending judgment of the nation during this tumultuous period.
