How did elizebath queen of scotts protect her country?

Elizabeth I of England and Mary, Queen of Scots were two different people. They were cousins. Mary plotted to overthrow Elizabeth, so Elizabeth had her executed. Elizabeth protected her country from its greatest enemy, Spain, by funding privateers (aka pirates) to prey on Spanish ships off the coast of North America, and by building a fleet of her own that decisively defeated the Spanish "Armada" with the help of a bad storm.
