Amenhotep III (Hellenized as Amenophis III; Egyptian Amāna-Ḥātpa; meaning Amun is Satisfied), also known as Amenhotep the Magnificent, was the ninth pharaoh of the Eighteenth Dynasty. According to different authors, he ruled Egypt from June 1386 to 1349 BC, or from June 1388 BC to December 1351 BC/1350 BC, after his father Thutmose IV died. Amenhotep III was Thutmose's son by a minor wife, Mutemwiya.
His reign was a period of unprecedented prosperity and artistic splendour, when Egypt reached the peak of its artistic and international power. When he died in the 38th or 39th year of his reign, his son initially ruled as Amenhotep IV, but then changed his own royal name to Akhenaten Amenhotep III in Wikipedia
