What is known as the Penal Laws begins with Mary's captivity in England. There was the northern rising; the Pope issued a Bull deposing Elizabeth, and Philip undertook to make away with her; for the Queen of Scots, once Queen of France, now fixed her hopes on Spain and the forces of the Counter-Reformation. The era of persecution began which threw England back for generations, while France, Germany, Austria, the Netherlands were striving for religious freedom. It was proposed to extirpate the Catholics. Negotiations were opened with the Scots to give them back their queen, on condition that they would at once put her to death. And when she had been condemned for plotting treason, Elizabeth asked her gaoler to murder her in her prison. The execution at Fotheringay gave Elizabeth that security at home which she could never have enjoyed while Mary lived. But it was the signal of danger from abroad. Philip II was already preparing for war with England when Mary bequeathed her rights to him. The legal force of the instrument was not great, but it gave him a claim to fight for, constituting the greatest enterprise of the Reformation struggle. Sixtus V, the ablest of the modern Popes, encouraged him. Personally, he much preferred Elizabeth to Philip, and he offered her favourable terms. But he gave his benediction, and even his money, to the Spaniards when there was a chance that they would succeed. And their chances, in the summer of 1588, seemed very good. The Armada was stronger, though not much stronger, than the English fleet; but the army that was to be landed at the mouth of the Thames was immeasurably superior to the English. This was so evident that Philip was dazzled and listened to no advice. They might have sailed for Cork and made Ireland a Spanish stronghold. They might have supplied Farnese with the land force that he required to complete the conquest of the revolted provinces, putting off to the following year the invasion of England. When they came in sight of Plymouth, Recalde, one of the victors of Lepanto, and Oquendo, whose name lasted as long as the Spanish navy, for the ship of the line that bore it was sunk in Cervera's action, demanded to fight. But the orders were peremptory to sail for Dunkirk and to transport Farnese to Margate. The Armada made the best of its way to Gravelines, where they were attacked before Farnese could embark, and the expedition failed.
