Whom did Plato believe made the best kings?

Plato believed that the best kings were philosopher-kings, individuals who possessed both wisdom and knowledge. In his work "The Republic," he argued that only those who understand the Forms, particularly the Form of the Good, are fit to rule justly. He maintained that such rulers would prioritize the common good over personal interests, leading to a more just and harmonious society. Thus, for Plato, the ideal rulers are those who have dedicated their lives to the pursuit of knowledge and virtue.
