What No One Told You About Philip II and Portugal: How He United the Entire Iberian Peninsula Under His Crown

The story of Philip II is one of absolute power, court intrigues, and the unbridled ambition of a monarch who dreamed of an empire that encompassed the entire Iberian Peninsula. In 1580, following the death of the last king of Portugal, Philip II seized the opportunity to claim the Portuguese crown, creating the controversial Iberian Union that would unite Spain and Portugal under a single banner. But what lies behind this union? Was it truly a triumph or the beginning of an inevitable decline?

The Context of the Union: Death and Ambition in 1580

The death of King Henry I of Portugal in 1580 left a power vacuum in the small but powerful kingdom. Henry had no heir, which unleashed a struggle for the throne among several claimants. Meanwhile, in Spain, Philip II, heir to the House of Habsburg and king of a vast empire, saw a golden opportunity to expand his dominion. Through astute diplomatic maneuvers and the use of force, Philip II claimed the Portuguese throne, marking the start of a period that many contemporaries described as a "forced union."

According to chroniclers of the time, the union was not warmly received in Portugal. Many Portuguese viewed Philip II as an usurper. However, the Spanish king had aspirations beyond mere territory; his vision included the consolidation of an empire that stretched from the Atlantic oceans to the lands of the East. With this ambition, Philip II became a polarizing figure, admired by some and vilified by others.
