Very rare first edition, in Russian and French, of a treaty for friendship and commerce concluded at St Petersburg, negotiated between Tsarina Catherine the Great of Russia and King Christian VII of Denmark. The relationship between the two countries had become hostile after Peter III became the Russian Tsar in 1762. His descent from Holstein-Gottorf led to territorial conflicts between the two powers and even to a threat of war. When Catherina II took the throne their relation stabilized. In 1765 they made an alliance and in the 1773 Treaty of Tsarskoe Selo Russia returned Schleswig-Holstein to Denmark in exchange for Russian control over the Duchy of Oldenburg. The present treaty emphasizes the "peace" and "eternal friendship" between Russia and Denmark and gives specific conditions for trade.
