His friends now looked forward to a brilliant diplomatic career for him, but the unfavorable climate soon led him to resign the appointment and return to America. But the St. Petersburg visit was not fruitless, for three years afterward he published an essay in the North American Review which showed a keen appreciation of Russian political conditions. The article was called "A Memoir of the Life of Peter the Great," and its appearance surprised the critics who had justly condemned a novel previously published by the young author. His essay portrayed the character of the great Peter, half king and half savage. It showed a full appreciation of the difficulties that hindered the establishment of a great monarchy, and paid due honor to that force of will, savage courage, and ideal patriotism that laid the foundations of Russia's greatness. The reader is made to see this fiery Sclav, building up a new Russia from his ice-fields and barren valleys; a Russia of great cities, imperial armies, vast commerce, and splendid hopes. It was a brilliant and scholarly narrative of the achievement of a great man, and it placed Motley among the writers of highest promise.
A year later he began collecting materials for the serious work of his life. For his subject he chose the story of the old Frisians or Hollanders who rescued from the sea a few islands formed by the ooze and slime of ages, and laid thereon the foundations of a great nation. They raised dykes to keep back the sea, built canals to serve as roads, turned bogs into pasture-lands and morasses into grain-fields, fought with the Romans, founded cities, laid the foundations of the vast maritime commerce of to-day, and finally, in the sixteenth century, when the wealth of their merchants, the power of their cities, and the progress of their arts were the wonder of the world, met their worst foe in the person of their own king, Philip II.
From the beginning the Hollanders or Netherlanders had cherished a savage independence which commanded respect even in barbarous ages, and this characteristic insured a quarrel between them and their ruler. Philip II. was King of Spain and of Sicily as well as of Holland. Born in Spain, he could not speak a word of Dutch. He was haughty, overbearing, and unscrupulous, and he resolved to make the Hollanders see in him a master as well as a king. Already in his father's reign there had been trouble because of the growing Protestantism which many of the Hollanders favored. Already some of the chief Dutch cities had been punished for resisting the Emperor's authority, and their burghers sentenced to kneel in sackcloth and beg him to spare their homes from destruction. These things happened in his father's time and had made an impression upon Philip II., who saw that in every case the royal power had been triumphant, and he believed himself invincible.
Motley painted the life of Philip from the day of his inauguration through all the years of revolt, bloodshed, and horror which marked his reign. He saw that this rebellion of the Hollanders meant less the discontent of a people with their king than the growth of a great idea, the idea that civil and religious liberty is the right of all men and nations. To Motley's mind the struggle seemed like some old battle between giants and Titans. Unlike other historians, who looked over the world for a subject, rejecting first one and then another, Motley's subject took possession of him and would not be rejected. His work was born, as a great poem or picture is born, from a glimpse of things hidden from other eyes.
But at once he discovered that Prescott had already in contemplation a history of Philip II. This was a severe blow to all his hopes. But he resolved to see Prescott, lay the matter before him, and abide by his decision, feeling that the master of history, who was the author of the Conquest of Mexico and the Conquest of Peru, would be the best adviser of a young and unknown writer.
Prescott received the idea with the most generous kindness, advised Motley to undertake the work, and placed at his disposal all the material which he himself had collected for his own enterprise.
After several years the book appeared in 1856, under the title The Rise of the Dutch Republic.
To write this book Motley dwelt for years in the world of three hundred years ago, when the whole of Europe was shaken by the new Protestantism, when Raleigh and Drake were sailing the Atlantic and adding the shores of the new world to English dominion, the French settling Canada and the Mississippi Valley, Spain sending her mission priests to California, and the Huguenots establishing themselves in Florida. Thus the foundations of the American Republic were being laid, while Philip was striving to overthrow the freedom of the Netherlands.
Leaving the nineteenth century as far behind him as he could, Motley established himself successively at Berlin, Dresden, The Hague, and Brussels, in order to consult the libraries and archives of state which contained documents relating to the revolt of the Netherlands against Philip II. In speaking of his work in the libraries of Brussels, he says that at this time only dead men were his familiar friends, and that he was at home in any country, and he calls himself a worm feeding on musty mulberry leaves out of which he was to spin silk. Day after day, year after year, he haunted the old libraries, whose shadows held so many secrets of the past, until the personalities of those great heroes who fought for the liberty of Holland were as familiar as the faces of his own children. William of Orange, called the Silent, the Washington of Dutch independence, Count Egmont, Van Horn, and all that band of heroes who espoused the cause of liberty, came to be comrades.
