Career
He entered the Holstein-Gottorp service, and after the death of the duchess Hedwig Sophia, Charles XII of Sweden’s sister, became very influential during the minority of her son Duke Charles Frederick. His earlier policy aimed at strengthening Holstein-Gottorp at the expense of Denmark. With this object, during Charles XII’s stay at Altranstädt (1706-1707), he tried to divert the king’s attention to the Holstein question, and six years later, when the Swedish commander, Magnus Stenbock, crossed the Elbe, Görtz rendered him as much assistance as was compatible with not openly breaking with Denmark, even going so far as to surrender the fortress of Tönning to the Swedes. Görtz next attempted to undermine the grand alliance against Sweden by negotiating with Russia, Prussia and Saxony for the purpose of isolating Denmark, or even of turning the arms of the allies against her, a task by no means impossible in view of the strained relations between Denmark and the tsar. The plan foundered, however, on the refusal of Charles XII to save the rest of his German domains by ceding Stettin to Prussia. Another simultaneous plan of procuring the Swedish crown for Duke Charles Frederick also came to nought. Görtz first suggested the marriage between the duke of Holstein and the tsarevna Anne of Russia, and negotiations were begun in St. Petersburg with that object.
Charles XII
On the arrival of Charles XII from Turkey at Stralsund, Görtz was the first to visit him, and emerged from his presence chief minister or “grand-vizier“ as the Swedes preferred to call the bold and crafty satrap, whose absolute devotion to the Swedish king took no account of the intense wretchedness of the Swedish nation. Görtz, himself a man of uncommon audacity, seems to have been fascinated by the heroic element in Charles’s nature and was determined, if possible, to save him from his difficulties. He owed his extraordinary influence to the fact that he was the only one of Charles’s advisers who believed, or pretended to believe, that Sweden was still far from exhaustion, or at any rate had a sufficient reserve of power to give support to an energetic diplomacy - Charles’s own opinion, in fact.
Swedish plenipotentiary
Görtz’s position, however, was highly peculiar. Ostensibly, he was only the Holstein minister at Charles’s court, in reality he was everything in Sweden except a Swedish subject - finance minister, plenipotentiary to foreign powers, factotum, and responsible to the king alone, though he had not a line of instructions. But he was just the man for a hero in extremities, and his whole course of procedure was, of necessity, revolutionary. His chief financial expedient was to debase, or rather ruin, the currency by issuing copper tokens redeemable in better times; but it was no fault of his that Charles XII, during his absence, flung upon the market too enormous an amount of this copper money for Görtz to deal with. By the end of 1718 it seemed as if Görtz’s system could not go on much longer, and the hatred of the Swedes towards him was so intense and universal that they blamed him for Charles XII’s tyranny as well as for his own. Görtz hoped, however, to conclude peace with at least some of Sweden’s numerous enemies before the crash came and then, by means of fresh combinations, to restore Sweden to her rank as a great power.
Downfall
It must be admitted that, in pursuance of his ”system” Görtz displayed a genius for diplomacy which would have done honour to a Metternich or a Talleyrand. He desired peace with Russia first of all, and at the Congress of Åland even obtained relatively favourable terms, only to have them rejected by his obstinately optimistic master. Simultaneously, Görtz was negotiating with Cardinal Alberoni and with the Whigs in England; but all his ingenious combinations collapsed like a house of cards on the sudden death of Charles XII. The whole fury of the Swedish nation instantly fell upon Görtz. After a trial before a special commission, which was a parody of justice - the accused was not permitted to have any legal assistance or the use of writing materials - he was condemned to decapitation and promptly executed. Perhaps Görtz deserved his fate for “unnecessarily making himself the tool of an unheard-of despotism,” but his death was certainly a judicial murder, and some historians even regard him as a political martyr.
