Introduction: Exactly 200 years after the Proclamation of the Independence of Brazil, little is known about the psychopathological context that influenced the decision-making of the young Emperor D. Pedro I and that culminated in this important milestone in national history. Method: Narrative review based on secondary sources. Results: Psychiatric morbidity was very high in the ancestors of D. Pedro I, both on the maternal and paternal sides, a phenomenon favored by the high rates of consanguineous marriages encouraged within the royal family. It seems evident the presence of a temperamentopathy in the case of D. Pedro I. His pathological temperament was characterized by: explosiveness, impulsiveness, irritability, inflexibility. It remains to be seen whether this temperament resulted predominantly from genetic contributions (paternal and maternal), or whether due to the organic brain disorder associated with epilepsy. Conclusions: The high prevalence of consanguinity and mental illness in the Portuguese monarchy likely contributed to their mental health history. The pathological temperament of D. Pedro I and his organic personality disorder associated with epilepsy exerted a great influence on the Brazilian political, historical and territorial construction.
