At length he removed to the little town of Wesel, on the Lower Rhine, in the beginning of May, 1707. He had a wife and four children to maintain, and living was much more reasonable at Wesel than at the Hague. His wife's modest fortune enabled him to live there to the end of his days. Wesel was also a resort of the French refugees—persons of learning and taste, though of small means. It was at his modest retreat at Wesel that Rapin began to arrange the immense mass of documents which he had been accumulating during so many years, relating to the history of England. The first work which he published was "A Dissertation on the Origin and Nature of the English Constitution." It met with great success, and went through many editions, besides being translated into nearly all the continental languages.

He next proceeded with his great work, "The History of England." During his residence in Ireland and England, he had read with great interest all books relating to the early history of the Government of England. He began with, the history of England after the Norman Conquest; but he found that he must begin at the beginning. He studied the history of the Anglo-Saxons, but found it "like a vast forest, where the traveller, with great difficulty, finds a few narrow paths to guide his wandering steps. It was this, however, that inspired him with the design of clearing this part of the English history, by removing the rubbish, and carrying on the thread so as to give, at least, a general knowledge of the earlier history." Then he went back to Julius Cæsar's account of his invasion of Britain, for the purpose of showing how the Saxons came to send troops into this country, and now the conquest which had cost them so much was at last abandoned by the Romans. He then proceeded, during his residence in England, with his work of reading and writing; but when he came to the reign of Henry II. he was about to relinquish his undertaking, when an unexpected assistance not only induced him to continue it, but to project a much larger history of England than he had at first intended.

This unexpected assistance was the publication of Rymer's "Fœdera," at the expense of the British Government. The volumes as they came out were sent to Rapin by Le Clerc (another refugee), a friend of Lord Halifax, who was one of the principal promoters of the publication. This book was of infinite value to Rapin in enabling him to proceed with his history. He prepared abstracts of seventeen volumes (now in the Cottonian collection), to show the relation of the acts narrated in Rymer's "Fœdera" to the history of England. He was also able to compare the facts stated by English historians with, those of the neighbouring states, whether they were written in Latin, French, Italian, or Spanish.

The work was accomplished with great labour. It occupied seventeen years of Rapin's life. The work was published at intervals. The first two volumes appeared in November, 1723. During the following year six more volumes were published. The ninth and tenth volumes were left in manuscript ready for the press. They ended with the coronation of William and Mary at Westminster. Besides, he left a large number of MSS., which were made use of by the editor of the continuation of Rapin's history.

Rapin died at Wesel in 1725, at the age of sixty-four. His work, the cause of his fatal illness, was almost his only pleasure. He was worn out by hard study and sedentary confinement, and at last death came to his rescue. He had struggled all his life against persecution; against the difficulties of exile; against the enemy; and though he did not die on the field of battle, he died on the breach pen in hand, in work and duty, striving to commemorate the independence through which a noble people had worked their way to ultimate freedom and liberty. The following epitaph was inscribed over his grave:—

"Ici le casque et la science,
L'esprit vif, la solidité,
La politesse et la sincérité
Ont fait une heureuse alliance,
Dont le public a profité."

The first edition of Rapin's history, consisting of ten volumes, was published at the Hague by Rogessart. The Rev. David Durand added two more volumes to the second edition, principally compiled from the memoranda left by Rapin at his death. The twelfth volume concluded the reign of William III.

The fourth edition appeared in 1733. Being originally composed and published in French, the work was translated into English by Mr. N. Tindal, who added numerous notes. Two editions wore published simultaneously in London, and a third translation was published some sixty years later. The book was attacked by the Jacobite authors, who defended the Stuart party against the statements of the author. In those fanatical times impartiality was nothing to them. A man must be emphatically for the Stuarts, or against them. Yet the work of Rapin held its ground, and it long continued to be regarded as the best history that had up to that time been written.

The Rapin family are now scattered over the world. Some remain in Holland, some have settled in Switzerland, some have returned to France, but the greater number are Prussian subjects. James, the only son of Rapin, studied at Cleves, then at Antwerp, and at thirty-one he was appointed to the important office of Director of the French Colonies at Stettin and Stargardt. Charles, Rapin's eldest brother, was a captain of infantry in the service of Prussia. Two sons of Louis de Rapin were killed in the battles of Smolensko and Leipsic.

Many of the Rapins attained high positions in the military service of Prussia. Colonel Philip de Rapin-Thoyras was the head of the family in Prussia. He was with the Allied Army in their war of deliverance against France in the years 1813, 1814, and 1815. He was consequently decorated with the Cross and the Military Medal for his long and valued services to the country of his adoption.
