The last of the 4th dynasty kings (if memory serves) built his mastaba there, after his immediate predecessors had left the Giza monuments to wow the world (also, Abu Roash, but the Djedjefre pyramid there wasn't finished, perhaps barely begun). I've often thought that the dynastic squabbles continued, and the Khufu descendants lost control of the area, then the 5th dynasty would have been in business such that the two dynasties overlapped a bit. Anyway, the first (and probably most effective) plunderers of the monuments of ancient Egypt were the ancient Egyptians themselves, so most of what is left is kinda ho-hum by comparison with
Yuya and Tuya, Tut, and just a few other big caches discovered or rediscovered in modern times.
