Periodization of Ancient Egypt in the context of "Old Kingdom"

The Third Intermediate Period of ancient Egypt began with the death of Pharaoh Ramesses XI in 1077 BC, which ended the New Kingdom, and was eventually followed by the Late Period. Various points are offered as the beginning for the latter era, though it is most often regarded as dating from the foundation of the Twenty-Sixth Dynasty by Psamtik I in 664 BC, following the departure of the Nubian Kushite rulers of the Twenty-fifth Dynasty after they were driven out by the Assyrians under King Ashurbanipal. The use of the term "Third Intermediate Period", based on the analogy of the well-known First and Second Intermediate Periods, was popular by 1978, when British Egyptologist Kenneth Kitchen used the term for the title of his book on the period. While Kitchen argued that the period was 'far from being chaotic' and hoped that his work would lead to the abolishment of the term, with his own preference being the 'Post-Imperial epoch', his use of the term as a title seems only to have entrenched its use.

The period was ruled by non-native Egyptians and is viewed as one of decline and political instability including division of the state, coinciding with the Late Bronze Age collapse of civilizations in the ancient Near East and Eastern Mediterranean (including the Greek Dark Ages).

In ancient Egyptian history, dynasties are series of rulers sharing a common origin. They are usually, but not always, traditionally divided into 33 pharaonic dynasties; these dynasties are commonly grouped by modern scholars into "kingdoms" and "intermediate periods".

The first 30 divisions come from the 3rd century BC Egyptian priest Manetho, whose history Aegyptaiaca was probably written for a Greek-speaking Ptolemaic ruler of Egypt but survives only in fragments and summaries. The names of the last two, the short-lived Persian-ruled 31st Dynasty and the longer-lasting Ptolemaic Dynasty, are later coinings.

In ancient Egyptian history, the Old Kingdom is the period spanning c. 2700–2200 BC. It is also known as the "Age of the Pyramids" or the "Age of the Pyramid Builders", as it encompasses the reigns of the great pyramid-builders of the Fourth Dynasty, such as King Sneferu, under whom the art of pyramid-building was perfected, and the kings Khufu, Khafre and Menkaure, who commissioned the construction of the pyramids at Giza. Egypt attained its first sustained peak of civilization during the Old Kingdom, the first of three so-called "Kingdom" periods (followed by the Middle Kingdom and New Kingdom), which mark the high points of civilization in the lower Nile Valley.

The concept of an "Old Kingdom" as one of three "golden ages" was coined in 1845 by the German Egyptologist Baron von Bunsen, and its definition evolved significantly throughout the 19th and the 20th centuries. Not only was the last king of the Early Dynastic Period related to the first two kings of the Old Kingdom, but the "capital", the royal residence, remained at Ineb-Hedj, the Egyptian name for Memphis. The basic justification for separating the two periods is the revolutionary change in architecture accompanied by the effects on Egyptian society and the economy of large-scale building projects.

The First Intermediate Period, described as a 'dark period' in ancient Egyptian history, spanned approximately 125 years, c. 2181 – c. 2055 BC, after the end of the Old Kingdom. It comprises the Seventh (although this is mostly considered spurious by Egyptologists), Eighth, Ninth, Tenth, and part of the Eleventh Dynasties. The concept of a "First Intermediate Period" was coined in 1926 by Egyptologists Georg Steindorff and Henri Frankfort.

Very little monumental evidence survives from this period, especially from the beginning of the era. The First Intermediate Period was a dynamic time in which rule of Egypt was roughly equally divided between two competing power bases. One of the bases was at Heracleopolis in Lower Egypt, a city just south of the Faiyum region, and the other was at Thebes, in Upper Egypt. It is believed that during that time, temples were pillaged and violated, artwork was vandalized, and the statues of kings were broken or destroyed as a result of the postulated political chaos. The two kingdoms would eventually come into conflict, which would lead to the conquest of the north by the Theban kings and to the reunification of Egypt under a single ruler, Mentuhotep II, during the second part of the Eleventh Dynasty. This event marked the beginning of the Middle Kingdom of Egypt.
