Analysis of information sources in references of the Wikipedia article "David" in English language version.
The history of Palestine and of its peoples is very different from the Bible's narratives, whatever political claims to the contrary may be. An independent history of Judea during the Iron I and Iron II periods has little room for historicizing readings of the stories of I-II Samuel and I Kings.
The geographical extent of David's—even extrabiblically probable—rule as well as its precise date remain controversial in research. Yet, divorced from the biblical findings, there is nothing to suggest it should be dated around 1000 BCE. (p. 176) …the local ruler David, whenever—tenth or ninth century BCE—he is to be dated. (p. 190)
The events of the book took place in the last half of the eleventh century and the early part of the tenth century BC, but it is difficult to determine when the events were recorded. There are no particularly persuasive reasons to date the sources used by the compiler later than the events themselves, and good reason to believe that contemporary records were kept (cf. 2 Sam. 20:24–25).
The stories of Solomon are larger than life. According to the stories, Solomon imported 100,000 workers from what is now Lebanon. Well, the whole population of Israel probably wasn't 100,000 in the 10th century. Everything Solomon touched turned to gold. In the minds of the biblical writers, of course, David and Solomon are ideal kings chosen by Yahweh. So they glorify them. Now, archeology can't either prove or disprove the stories. But I think most archeologists today would argue that the United Monarchy was not much more than a kind of hill-country chiefdom. It was very small-scale.
