The naval battle in 1588 that marked the decline of the Spanish Armada was the Battle of Gravelines. This confrontation occurred during a failed attempt by King Philip II of Spain to invade England. The Spanish fleet faced challenges, including poor communication, unfavorable weather conditions, and a more maneuverable English navy commanded by Sir Francis Drake. The defeat of the Armada not only weakened Spain's naval dominance but also bolstered England's maritime power and contributed to the rise of British naval supremacy, altering the balance of power in Europe.
