Edward of Portugal vs Gao Wei

Edward succeeded his father John I as King of Portugal. He inherited a prosperous kingdom but faced challenges including the ongoing exploration efforts sponsored by his brother Henry the Navigator and tensions with the nobility.

Edward authorized a disastrous expedition to capture Tangier in Morocco, led by his brother Henry the Navigator. The Portuguese forces were defeated, and Edward's younger brother Ferdinand was taken hostage, leading to a national crisis.

Edward wrote the 'Leal Conselheiro' (Loyal Counselor), a philosophical and moral treatise for the nobility. This work reflects his humanist education and established him as a philosopher-king, influencing Portuguese literature and political thought.

Edward died of the plague at age 47, leaving his young son Afonso V as king. His death triggered a regency crisis, as his widow Eleanor of Aragon and his brother Pedro disputed control, leading to political instability in Portugal.

Gao Wei ascended the throne as emperor of Northern Qi at age eight, with his mother Empress Dowager Hu and officials serving as regents. His reign was marked by incompetence, corruption, and neglect of state affairs, leading to the dynasty's decline.

Northern Zhou forces under Emperor Wu conquered Northern Qi. Gao Wei was captured and later executed, ending the Northern Qi dynasty. His incompetence, including favoring eunuchs and neglecting defense, was a major cause of the defeat.
