The Iron Islands

Because to keep them in line, their sons and brothers were taken to Egypt and held for ransom, exactly like Theon Greyjoy in the Game of Thrones, who was held hostage in Winterfell in order to keep his father alive.

Balon Greyjoy, and the Iron Islands in line.

They weren't kept in cells, but rather were treated as honored guests and educated in Egypt.

Like Theon, who became more like his adopted family of northerners rather than his seafaring relatives, these Canaanites became more Egyptian than Canaanite.

It would take too long to list all of the battles and wars the two houses then found themselves on opposite sides of, but it's a lot.

The resistance against House Hoare of the Iron Islands, the Dance of the Dragons, the Blackfire Rebellion, the War of the Five Kings, and so on.

Perhaps sometimes they were genuinely supportive of different causes, but often their old enmity was what led them to picking sides opposing each other.

Mm

... um, in Theon Greyjoy's crew when they left the Iron Islands, and he was one of the main ones in Theon's ear telling him to betray Robb and go take Winterfell.

And-

Oh, yeah, I just watched that.
