Foreign policy , 1762 After Peter succeeded to the Russian throne (), he withdrew Russian forces from the
Seven Years' War and concluded a
peace treaty () with Prussia (dubbed the "Second
Miracle of the House of Brandenburg"). He gave up Russian conquests in Prussia and offered 12,000 troops to make an alliance with Frederick II of Prussia (). Russia thus switched from an enemy of Prussia to an ally—Russian troops withdrew from
Berlin and marched against the Austrians. This dramatically shifted the
balance of power in Europe, suddenly handing the delighted Frederick the initiative. Frederick recaptured southern
Silesia (October 1762) and subsequently forced Austria to the
negotiating table. As Duke of Holstein-Gottorp, Peter planned war against
Denmark-Norway in order to restore parts of
Schleswig to his Duchy. He focused on making alliances with Sweden and with Great Britain to ensure that they would not interfere on Denmark's behalf, while Russian forces gathered at
Kolberg in Russian-occupied
Pomerania. Alarmed at the Russian troops concentrating near their borders, unable to find any allies to resist Russian aggression, and short of money to fund a war, the government of Denmark threatened in late June to invade the
free city of
Hamburg in northern Germany to force a loan from it. Peter considered this a
casus belli and prepared for open warfare against Denmark. In June 1762, 40,000 Russian troops assembled in Pomerania under General
Pyotr Rumyantsev, preparing to face 27,000 Danish troops under the French general
Count St. Germain in case the Russian–Danish freedom conference (scheduled for 1 July 1762 in Berlin under the patronage of Frederick II) failed to resolve the issue. However, shortly before the conference, Peter lost his throne () and the conference did not occur. The issue of Schleswig remained unresolved. Peter was accused of planning an unpatriotic war. While historically Peter's planned war against Denmark-Norway was seen as a political failure, recent scholarship has portrayed it as part of a pragmatic plan to secure his Holstein-Gottorp duchy and to expand the common Holstein-Russian power northward and westwards. Peter III believed gaining territory and influence in Denmark and Northern Germany was more useful to Russia than taking
East Prussia. Peter exempted nobles from compulsory civil and military service during peacetime and allowed them to freely travel abroad. He forbade landowners from murdering peasants at the penalty of lifelong exile and ended the persecution of the
Old Believers. He also issued a manifesto proclaiming the secularisation of church lands, which he never lived to see realised but which Catherine, a convinced secularist, began implementing during her own reign. While Catherine continued some of Peter's policies, she also reversed others. For example, Peter abolished the
Secret Chancellery, the
secret police of the Russian Empire, stating that he objected to the arbitrary arrests and torture it carried out. Catherine soon reestablished it under a different name, the
Secret Expedition. Peter III's economic policy reflected the rising influence of Western
capitalism and the merchant class or "
Third Estate" that accompanied it. He established the first state bank in Russia, rejected the nobility's monopoly on trade and encouraged
mercantilism by increasing grain exports and forbidding the import of sugar and other materials that could be found in Russia. ==Overthrow and death==
