Philip II, a devout Catholic, saw Elizabeth I as a heretic who had abandoned the true faith and had contributed to the spread of Protestantism in Europe. The Spanish king’s deep religious convictions led him to believe that he had a divine duty to protect Catholicism and, if necessary, to forcefully rid the world of Protestant influence. This ideology led to a growing animosity between the two nations, as Spain sought to reassert its dominance and restore Catholicism across Europe, while England, under Elizabeth’s leadership, challenged Spain’s religious and imperial ambitions.
The tensions between the two powers were also driven by political and economic competition. By the late 16th century, Spain had established a vast empire in the Americas, reaping tremendous wealth from its colonies. However, England, with its growing navy and its rising influence in world trade, was emerging as a rival power. England’s naval raids on Spanish ships and colonies were a major source of friction. The most notable of these raids was the attack led by Sir Francis Drake, who in 1587 destroyed a significant portion of the Spanish fleet while it was docked in Cadiz. These actions not only caused financial losses for Spain but also deeply humiliated the Spanish monarchy.
