Others point however to the consistency between the existing historical sources all crediting Pepi with over 90 years of reign. Finally, the lack of evidence beyond his 62nd year does not preclude a much longer reign, especially in view of the decay of the Egyptian state into the chaos of the First Intermediate Period at the end of Pepi 's reign.
