The Middle Kingdom is the period from the end of the First Intermediate Period to the beginning of the Second Intermediate Period. In addition to the Twelfth Dynasty, some scholars include the Eleventh, Thirteenth and Fourteenth Dynasties in the Middle Kingdom. The Middle Kingdom can be noted for the expansion of trade outside of the kingdom that occurred during this time. This opening of trade eventually led to the downfall of the Middle Kingdom, induced by an invasion from the Hyksos.
