Who Was Omri?

Q. Thank you so much for your commitment in sharing God’s word!  My question concerns Micah 6:16. The NKJ version reads,

For the statutes of Omri are kept; All the works of Ahab’s house are done; and you walk in their counsels, That I make you a desolation, And your inhabitants a hissing. Therefore you shall bear the reproach of My people.

My question is who is Omri? What is his historical Old Testament significance? I am familiar with Ahab and understand his and Jezebel’s wickedness but who is Omri?

A. According to 1 Kings 16:21-28 Omri was a king of Israel, founder of the Northern Capital City of Samaria, and father of King Ahab.  Verse 25 says he sinned more than all the kings before him.
