The First Intermediate Period, often described as a "dark period" in ancient Egyptian history, spanned approximately one hundred twenty-five years, from ca. 2181–2055 BC, after the end of the Old Kingdom. It included the seventh, eighth, ninth, tenth, and part of the eleventh dynasties. Very little monumental evidence survives from this period, especially towards the beginning of the era. The First Intermediate Period was a dynamic time in history where rule of Egypt was roughly divided between two competing power bases. One of those bases resided at Heracleopolis in Lower Egypt, a city just south of the Faiyum region. The other resided at Thebes in Upper Egypt. It is believed that during this time, the temples were pillaged and violated, their existing artwork was vandalized, and the statues of kings were broken or destroyed as a result of this alleged political chaos. These two kingdoms would eventually come into conflict, with the Theban kings conquering the north, resulting in reunification of Egypt under a single ruler during the second part of the eleventh dynasty.
