The Northern Kingdom (Israel)
The Northern Kingdom of Israel consisted of 10 of the tribes (excluding Judah and Benjamin). It lasted for about 210 years until it was destroyed by Assyria in 722 BC. Its capital was Samaria. Every king of Israel was evil. In the northern kingdom there were 9 dynasties (family lines of kings) and 19 kings in all. An average of 11 years to a reign. 8 of these kings met death by violence.
The epitaph written over every one of its kings was:
I Kings 15:34 "And he did evil in the sight of the LORD, and walked in the way of Jeroboam, and in his sin by which he had made Israel to sin. "
It was king Ahab who introduced Baal worship to them.
I Kings 16:30-33 "Now Ahab the son of Omri did evil in the sight of the LORD, more than all who were before him. And it came to pass, as though it had been a trivial thing for him to walk in the sins of Jeroboam the son of Nebat, that he took as wife Jezebel the daughter of Ethbaal, king of the Sidonians; and he went and served Baal and worshiped him. Then he set up an altar for Baal in the temple of Baal, which he had built in Samaria. And Ahab made a wooden image. Ahab did more to provoke the LORD God of Israel to anger than all the kings of Israel who were before him."
God attempted to save the northern kingdom of Israel by sending them Elijah and Elisha who were his prophets "mouthpieces", they lived during the period from 875-800 BC.
