how long did the old kingdom period of egyptian civilization last
Old Kingdom of Egypt The Old Kingdom, in ancient Egyptian history, is the period in the third millennium (c. 2686–2181 BC) also known as the 'Age of the Pyramids' or 'Age of the Pyramid Builders' as it includes the great 4th Dynasty when King Sneferu perfected the art of pyramid building and the pyramids of Giza were constructed under the kings Khufu, Khafre and Menkaure.[1] Egypt attained its first continuous peak of civilization – 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.
Ancient history Ancient history is the aggregate of past events[1] from the beginning of recorded human history and extending as far as the Early Middle Ages or the Postclassical Era. The span of recorded history is roughly 5,000 years, beginning with Sumerian Cuneiform script, the oldest discovered form of coherent writing from the protoliterate period around the 30th century BC.[2]
