At the time Drake first went to sea, England and Spain were by no means friendly. Henry the Eighth of England had ill-treated his wife, who was a Spanish princess. In addition he had drawn the English people away from the Church of Rome. These things were most displeasing to Spain, but there was still another reason for disagreement. The interests of the two countries were opposed commercially, and this was the most important cause of contention. Spain claimed by right of discovery, and gift of the Pope of Rome, all the land in the new world except Brazil (which belonged to Portugal), and held that no explorers or tradesmen, other than her own, had any rights on her waters or in her ports. English seamen denied much of this claim, and so frequent were the disputes arising upon the subject that the English sailors adopted as a maxim, “No peace beyond the line,” meaning the line which was, by the Pope’s decree, the eastern boundary of the Spanish claim. The favorite prey of the British mariners was the treasure ships carrying to Spain the precious cargoes of gold and silver from the rich mines of the new world. With the far richer ships of the Philippine and Indian trade, sailing on unknown waters, they had not, up to Drake’s time, been able to interfere. Drake, when a very young man, had joined a trading expedition to Mexico. While there the English were attacked by the Spanish in what the former considered a most treacherous manner. Drake’s brother and many of his comrades were killed, and their goods taken. After the battle he solemnly vowed to be revenged, and so thoroughly did he carry out his resolution that he was for years the terror of the Spanish seamen, and, by many of the superstitious common sailors, believed to be Satan himself come to earth in human form. Shortly after this unfortunate expedition Drake engaged in a marauding voyage to Panama, where he captured rich stores of gold and silver and precious stones. He gained such renown for his bravery and seamanship that upon coming home he found himself famous.
