@freemo Your argument seems to be that evidence of a political unit that drawers it's lineage from someone called "David", can be ignored because at some point prior the extent of that political power changed. Even though by your own requirements there is LESS evidence that a united kingdom existed at all. Whether the kingdom was united, or divided into Israel and Judah is not my concern. I'm just merely trying to argue that a political unit derived from the lineage of David existed.
