The takeover by the rulers of Herakleopolis was violent and is reflected in Manetho's description of Achthoes, the founder of the dynasty, as 'more terrible than his predecessors', who 'wrought evil things for those in all Egypt".

The following is a possible list of rulers of the Ninth Dynasty based on the Turin Canon, as egyptologists have differing opinions about the order of succession within the two dynasties. Among them, only Meryibre Khety and Nebkaure Khety are undoubtedly attested by archaeological finds:
