The Fall of the Eleventh
I'd also point out that Israel is far more important retrospectively than it was at the time. It's important for its religious influence for others. However, it was one of many small Kingdoms in the area and certainly paled in comparison to the giants like Egypt, Hatti, Assyria, Babylon, and Persia, and it also took a backseat to Phoenicia. In terms of comparable states, Phrygia, Elam, and Urartu are in the same area.
However, it's lasting impact is far, far greater. In that sense, I've always thought it worth a mention. But a city-state might be a fair compromise.
I disagree with this. I think the whole point of a culture being in as a civilisation is that it's unique, and Israel/the Jews - particularly referring to the BC's state - definitely fit that, especially considering how completely different the surrounding area has always been in culture. That said, Jerusalem as a religious CS also fits pretty well.
