HORN, ARVID BERNHARD, COUNT Swedish statesman, was born at Vuorentaka in Finland on April 6, 1664, of a noble but indigent family. He served for several years in the Netherlands, in Hungary under Prince Eugene, and in Flanders under Waldeck (169o-1695). He was one of the gen erals of Charles XII. in the earlier part of the great Northern War. In I'y04 he was entrusted with his first diplomatic mission, the deposition of Augustus II. of Poland and the election of Stanislaus I. Shortly after the accomplishment of this mission he was besieged by Augustus in Warsaw and compelled to sur render. In 1705 he was made a senator, in 1706 a count and in 1707 governor of Charles XII.'s nephew, the young duke Charles Frederick of Holstein-Gottorp. In 1710 succeeded Nils Gylden stolpe as prime minister. Both in 1710 and 1713 Horn was in favour of summoning the estates, but when in 1714 the diet adopted an anti-monarchical attitude, he gravely warned and ulti mately dissolved it. After the death of Charles XII. (1718) it was Horn who persuaded the princess Ulrica Leonora to relinquish her hereditary claims and submit to be elected queen of Sweden. He protested against the queen's autocratic behaviour, and re signed both the premiership and his senatorship. He was elected landtmarskalk at the diet of 172o, and contributed, on the resig nation of Ulrica Leonora, to the election of Frederick of Hesse as king of Sweden, whose first act was to restore to him the office of prime minister. For the next eighteen years he controlled both the foreign and the domestic affairs of Sweden, and it was owing to his care that Sweden so rapidly recovered from the condition in which the wars of Charles XII. had plunged her. Horn increased the influence of the diet and its secret committees in the solution of purely diplomatic questions, thus weakening the central government. In 1734, however, the opposition in the diet denounced his neutrality on the occasion of the war of the Polish Succession, when Stanislaus I., again appeared upon the scene as a candidate for the Polish throne; but Horn was still strong enough to prevent a rupture with Russia. Henceforth he was bitterly but unjustly accused of want of patriotism, and in 1738 was compelled at last to retire before the impetuous onslaught of the triumphant young Hat party. The rest of his life was spent at his estate at Ekebyholm, where he died on April 17, 1742. Horn in many respects resembled his contemporary Walpole. The situation of Sweden, made his policy necessarily opportunist, but it was an opportunism based on excellent common sense.
