MarkA, if you want to dispute the historicity of the "empire of David and Solomon," meaning the supposed empire which stretched from the River of Egypt to the Euphrates, that is one thing. There is a lot of reason to question whether that existed, and I have not, during this discussion, even mentioned it.
But as for the "United Israelite Kingdom" of David and Solomon, you are on far more shaky ground.
You are the one who claims the existence of this ghost empire that no contemporary power even noticed...
The only contemporary powers who left written records at all during this time period were Assyria and Egypt. Assyria during the time period in question (c. 1000-c. 925 BC, which is the most commonly used dates for the reigns of David and Solomon) was being ruled by a succession of weak kings about whose reigns we know very little, because they didn't leave much in the way of written records. We don't even have records of what these kings did themselves. Why should we expect to have records of the doings of a kingdom hundreds of miles away in Palestine?
As for Egypt, pretty much the same type of situation prevails. Egypt was ruled by weak Pharaohs who were totally absorbed with the internal affairs of Egypt and who did not generally record the doings of kingdoms outside their own realm.
It would be MORE surprising, in that context, if there WERE mentions of the Israelite kingdom in Assyrian and Egyptian records of the time, than it is that there are not.
...and that has no physical evidence for its existence.
There you are wrong. There is, in fact, physical evidence of it's existence.
First, there are the Solomonic gates at Megiddo, Gezer, Ashdod, Hazor, Beth Shemesh, and Lachish. These gates are virtually identical in design, and are dated by most archaelogists (i.e. those outside Israel Finkelstein and the other followers of the Copenhagen School) to the mid 10th century BC. The fact that at least two of these virtually identical gates (Megiddo and Hazor) were in what later became the northern Kingdom of Israel, while most of the others (Gezer, Beth Shemesh, and Lachish) were definitely in the territory of Judah, represents strong evidence of a unified kingdom at the time they were built. Otherwise, one would expect there to be significant differences in the design of the gates. Furthermore, the gate at Ashdod...which was a Philistine city...is likely evidence that, at this time, this united Israelite kingdom held sway over Philistine territory.
It is specifically stated in the Bible that the fortifications of these cities were rebuilt by the architects of King Solomon. I know you put no stock in the Bible as a historical document, but in this case, the archaelogy and the text does seem to be a close match.
Second, a large public building, which dates to the 10th Century BC and which may be
King David's Palace, has been discovered in Jerusalem.
As for the existence of the Davidic Dynasty, it is true that there are no documents dating to the 10th century which mention David or Solomon. However, there is a written record, dating from about a century after Solomon's death, which mentions the kings of the House of David. That is, of course, the
Tel Dan Stele. There may also be another reference to the dynasty in the
Mesha Stele.
Oh, I know that you will dismiss all this evidence and claim it is misdated or misinterpreted. But so far, the minority "minimalists" have not proven such a case, and there is more reason to believe that a united Israelite kingdom existed, than there is to believe that it did not.
