Who Was Josiah's Father? Amon, King of Judah
Josiah's father was Amon, son of Manasseh, who reigned only two years in Jerusalem and did evil in Yahweh's sight. After Amon was killed by his own servants, the people of the land put his young son Josiah on the throne.
Who Was Manasseh's Father? 2 Kings 21:1–18

Manasseh was Hezekiah's son, and the book of Kings gives him fifty-five years in Jerusalem and a verdict as Judah's worst king. His reign reversed his father's reforms and provoked a judgment announced before he died.
