Statue of Nyuserre Ini
in his youth and old age

Nyuserre Ini was a pharaoh of Ancient Egypt, the sixth ruler of the Fifth Dynasty during the Old Kingdom period. The younger son of Neferirkare Kakai and queen Khentkaus II and the brother of the short-lived king Neferefre, Nyuserre probably lived in the second half of the 25th century BCE and reigned for more than two decades. He was succeeded by Menkauhor Kaiu, who could have been his nephew and a son of Neferefre. Nyuserre built three pyramids for himself and his queens and completed a further three for his father, mother and brother, all in the necropolis of Abusir. His temple dedicated to the sun god Ra was named Shesepibre or "Joy of the heart of Ra"; it is the largest such temple that survives from the Old Kingdom. He also completed the Nekhenre, the Sun Temple of Userkaf in Abu Gorab, and the valley temple of Menkaure in the Giza necropolis. The state-sponsored funerary cult established at Nyuserre's death lasted until the Twelfth Dynasty of the Middle Kingdom. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
