Rehoboam

Rehoboam was the son of Solomon and king of what was left of his kingdom, namely the land of Judah.
In the book of 1 Kings, chapter 12, Rehoboam met with the people and they asked him if they could lighten their load, for his father laid a heavy burden on them.
He turned them away for three days as he consulted with the elders.  They gave advice, saying he should be a servant to the people and they'd do whatever he asked.  He did not like this advice, so he asked advice from younger men he had grown up with.  They said to punish the people harder than what his father did.
So that is what he did.
And in doing so divided the kingdom up even more.
