“ The Invincible Armada.—The execution of Mary Stuart led immediately to the memorable attempt against England by the Spanish Armada. Before her death the Queen of Scots had bequeathed to Philip II. of Spain her claims to the English crown. To enforce these rights, to avenge the death of Mary, to punish Elizabeth for rendering aid to his rebellious subjects in the Netherlands, and to deal a fatal blow to the Reformation in Europe by crushing the Protestants of England, Philip resolved upon making a tremendous effort for the conquest of the heretical and troublesome island. ”
