Ramesses XI
Since Ramesses XI had himself buried in Lower Egypt, Smendes rose to the kingship of Egypt, based on the well known custom that he who buried the king inherited the throne. Since Smendes buried Ramesses XI, he could legally assume the crown of Egypt and inaugurate the 21st Dynasty from his hometown at Tanis, even if he did not control Middle and Upper Egypt, which were now effectively in the hands of the High Priests of Amun at Thebes.
