The Second Intermediate Period marks a period when Ancient Egypt fell into disarray for a second time, between the end of the Middle Kingdom and the start of the New Kingdom. It is best known as the period when the Hyksos made their appearance in Egypt and whose reign comprised the fifteenth and sixteenth dynasties. The brilliant Egyptian twelfth dynasty came to an end around 1800 BC with the death of Queen Sobekneferu (1807 BC 1803 BC). Apparently, she had no heirs, causing the twelfth dynasty to come to a sudden end as did the Golden Age of the Middle Kingdom, which was succeeded by the much weaker thirteenth dynasty of Egypt.
