Read 2 Kings 15 today.

This chapter includes many transition in leadership of Israel (the northern tribes). Most of these transitions took place as one king was assassinated by the one who sought to take the sitting king’s place on the throne. It is violent history as Israel was moving toward the time when it would be completely destroyed by the Assyrians.
The kings were not interested in the things of God. Their concern was gaining and holding (unsuccessfully) power for its own sake. I wonder how many of our own leaders began with good intentions, but drifted into the same thing.
2 Kings 15:10, 14, 25, 30 NLT
[10] Then Shallum son of Jabesh conspired against Zechariah, assassinated him in public, and became the next king.
[14] Then Menahem son of Gadi went to Samaria from Tirzah and assassinated him, and he became the next king.
[25] Then Pekah son of Remaliah, the commander of Pekahiah’s army, conspired against him. With fifty men from Gilead, Pekah assassinated the king, along with Argob and Arieh, in the citadel of the palace at Samaria. And Pekah reigned in his place.
[30] Then Hoshea son of Elah conspired against Pekah and assassinated him. He began to rule over Israel in the twentieth year of Jotham son of Uzziah.
Matthew 20:25-28 NLT
But Jesus called them together and said, “You know that the rulers in this world lord it over their people, and officials flaunt their authority over those under them. [26] But among you it will be different. Whoever wants to be a leader among you must be your servant, [27] and whoever wants to be first among you must become your slave. [28] For even the Son of Man came not to be served but to serve others and to give his life as a ransom for many.”
