Art. 4. His majesty the king of Sweden does, by the present treaty, as well for himself as for his successors to the throne and kingdom of Sweden, cede to his czarish majesty, and his successors to the Russian empire, in full, irrevocable and everlasting possession, the provinces which have been taken by his czarish majesty's arms from the crown of Sweden during this war, viz. Livonia, Esthonia, Ingria, and a part of Carelia, as likewise the district of the fiefs of Wybourg specified hereafter in the article for regulating the limits; the towns and fortresses of Riga, Dunamund, Pernau, Revel, Dorpt, Nerva, Wybourg, Kexholm, and the other towns, fortresses, harbours, countries, districts, rivers, and coasts, belonging to the provinces: as likewise the islands of Oesel, Dagoe, Moen, and all the other islands from the frontiers of Courland, towards the coasts of Livonia, Esthonia, and Ingria, and on the east side of Revel, and in the road of Wybourg, towards the south-east, with all the present inhabitants of those islands, and of the aforesaid provinces, towns, and countries; and in general, all their appurtenances, dependencies, prerogatives, rights, and advantages, without exception, in like manner as the crown of Sweden possessed them. To which purpose, his majesty the king of Sweden renounces for ever, in the most solemn manner, as well for his own part, as for his successors, and for the whole kingdom of Sweden, all pretensions which they have hitherto had, or could have, to the said provinces, islands, countries, and towns; and all the inhabitants thereof shall, by virtue of these presents, be discharged from the oath of allegiance, which they have taken to the crown of Sweden, in such wise as that his Swedish majesty, and the kingdom of Sweden, shall never hereafter either claim or demand the same, on any pretence whatsoever; but, on the contrary, they shall be and remain incorporated for ever into the empire of Russia. Moreover, his Swedish majesty, and the kingdom of Sweden, promise by these presents to assist and support from henceforth his czarish majesty, and his successors to the empire of Russia, in the peaceable possession of the said provinces, islands, countries, and towns; and that they will find out and deliver up to the persons authorized by his czarish majesty for that purpose, all the records and papers principally belonging to those places which have been taken away and carried into Sweden during the war.
