Final answer:
Hippias' transformation from ruling well to becoming mad and suspicious can be attributed to political factors. His despotic rule and the fear of losing power led to his descent into madness and paranoia.
Step-by-step explanation:
The reason for Hippias' transformation from ruling well to becoming mad and suspicious can be attributed to political factors. At first, Hippias ruled effectively, but his rule became increasingly despotic and tyrannical over time. This led to resentment among the people, and he became suspicious and paranoid, fearing plots against him.
One example of this is his reaction to the murder of his brother Hipparchus. After the assassination, Hippias became more repressive and started targeting his political opponents, leading to a further deterioration of his rule.
In summary, Hippias' descent into madness and suspicion was a result of his tyrannical rule and the fear of losing power.
