Abijah of Judah died in -912.

Judah has already.

Manasseh's predecessor, Hezekiah, took a reckless decision to rebel against Assyria and was responsible for events that led to the utter devastation of Judah, the extent of which is shown by archaeology. Far from being a lackey, Manasseh saved Judah from final annihilation. Under his policy of cooperation with Assyria, the Southern Kingdom emerged from the ruin brought about by Hezekiah, was reincorporated into the Assyrian economy and reached an unprecedented prosperity.

MANASSEH (Ma·nas′seh) [One Making Forgetful; One Who Makes Forget]. Joseph's firstborn son and a grandson of Jacob. After Joseph became Egypt's food administrator, Pharaoh gave him Asenath, the daughter of Potiphera the priest of On, as a wife, and she bore Joseph two sons, Manasseh and Ephraim. Joseph named his firstborn Manasseh, because, he said: "God has made me forget all my trouble and all the house of my father."-Ge 41:45, 50-52. When Jacob blessed Manasseh and Ephraim, he persisted in putting his right hand on Ephraim and his left on Manasseh, thereby placing the younger Ephraim before Manasseh. (Ge 48:13-20) As indicated thereby, Ephraim was to become greater than Manasseh. Manasseh had sons by a Syrian concubine (1Ch 7:14), and Joseph lived long enough to see the sons of Manasseh's son Machir.-Ge 50:22, 23. Insight on the Scriptures - Volume 2 (A Bible Encyclopedia)

If I counted correctly, King Manasseh would have been the 13th king of Judah. His father was Hezekiah, one of Judah's righteous kings. When King Hezekiah became sick to death, he was told he would die soon, but Hezekiah prayed fervently to be able to live and God promised him another 15 years. Three years later, Manasseh was born. When Manasseh was twelve years old, his father, Hezekiah, died and Manasseh became king. He was the most wicked of all the kings of either Judah OR Israel (which, today, we usually refer to as the "northern kingdom"; it's the portion that separated itself, preferring idol worship, after the death of King Solomon. II Kings 21:16, says Judah would be made desolate because King Manasseh had made the streets of Jerusalem to run red with the blood of innocent people. This included some of God's prophets as well. Jewish tradition says that after Isaiah, the prophet, told Manasseh to repent, he was taken outside and beheaded.
