Biography
John II of Portugal, known as 'The Perfect Prince,' was a monarch who ruled with an iron will and a singular focus on expansion. Ascending the throne in 1481, he immediately set about crushing the power of the nobility, reclaiming lands and authority for the crown. His court was a center of calculation, not just pageantry. John's true passion lay in the sea. He aggressively continued the work of his great-uncle, Henry the Navigator, turning Portugal's exploratory efforts into a state-directed enterprise of immense strategic importance. He dispatched Bartolomeu Dias to round the Cape of Good Hope in 1488, proving a sea route to Asia was possible. He also secretly funded Christopher Columbus before the Genoese sailor took his proposal to Spain. John's death in 1495, just as Vasco da Gama was preparing for his historic voyage, meant he never saw the full fruits of his planning, but he laid the indispensable groundwork for Portugal's golden age of empire.
