Armada, Spanish
(ahr-MAH-duh) A fleet of more than a hundred ships sent by King Philip II of Spain to conquer England in 1588. Although called the Invincible Armada, it was destroyed by a combination of English seamanship, Dutch reinforcements, and bad weather. Several thousand Spaniards were killed, and about half the Spanish ships were lost.
The defeat of the Armada was a sharp blow to the influence and prestige of Spain in the world and was an important step in Englands ascent to power.
