What happened 1079 AD

The Hohenstaufen, also called Staufer, was a noble dynasty of unclear origin that rose to rule the Duchy of Swabia from 1079 and to royal rule in the Holy Roman Empire during the Middle Ages from 1138 until 1254. The most prominent kings Frederick I (1155), Henry VI (1191) and Frederick II (1220) ascended the imperial throne and also ruled Italy and Burgundy. The non-contemporary name is derived from a family castle on the Hohenstaufen mountain at the northern fringes of the Swabian Jura near the town of Göppingen. Under Hohenstaufen reign the Holy Roman Empire reached its greatest territorial extent from 1155 to 1268.

Rameses III's death was followed by years of bickering among his heirs. Three of his sons ascended the throne successively as Ramesses IV, Rameses VI, and Rameses VIII. Egypt was increasingly beset by droughts, below-normal flooding of the Nile, famine, civil unrest, and corruption of officials. The power of the last pharaoh of the dynasty, Ramesses XI, grew so weak that in the south the High Priests of Amun at Thebes became the de facto rulers of Upper Egypt, and Smendes controlled Lower Egypt in the north, even before Rameses XI's death. Smendes eventually founded the twenty-first dynasty at Tanis.
