After losing Sicily, the Carthaginian general Hamilcar Barca and his son Hannibal didn't try to reclaim it directly. Instead, they built a new, resource-rich empire in Spain. Its vast mineral wealth funded a mercenary army, turning Spain into a formidable base from which to launch a revenge war against Rome.

Before returning to Portugal, King João VI advised his son Pedro to lead Brazil's independence movement if it seemed inevitable. This farsighted political move was designed to ensure the breakaway territory would remain under the control of the royal family.

In a rare display of monarchical creativity, Dom Pedro I, the first emperor of Brazil, personally composed the music for the new nation's "Hymn of Independence." While likely aided by court musicians, historians credit him with the composition.
