There's an idea growing on Israel's far left that the history of Jerusalem wasn't. Kind David wasn't, Solomon wasn't, lots of the Bible wasn't, and of course the purpose of all this is to undermine any Jewish claim to the land and especially the city of Jerusalem. The central figure of all this seems to be the Tel Aviv archeologist Israel Finkelstein, but it has branched out. Shlomo Sand, of course, eagerly lapped up their theories without offering any space to the colleagues who disagree.
Without getting into the details (which are actually interesting), it has always seemed to me the discussion is a bit pointless. There's no doubt the House of David existed and its capital was Jerusalem; most of the argument seems to be about how large and important the Kingdom of Judea was. And if it was small and of no particular regional geo-political significance, as the revisionists say, what of it? The significance of Kind David wasn't that he was a major war-lord (we're talking about Jews, not Vikings or Mongolians) but that he wrote some of the Psalms.
How significant is that, you ask? This significant:
Or, if you prefer King James: In his hand are the deep places of the earth: the strength of the hills is his also.
