Summary
Catherine the Great’s 1777 diplomacy epitomized the intersection of European power politics and territorial ambition during the American Revolutionary War. As Russia’s Empress since 1762, Catherine pursued an expansionist foreign policy targeting Ottoman territories in the Black Sea region and the Balkans. By 1777, her diplomatic machinery had secured critical alliances: negotiations with Austria — which would culminate in the secret 1781 Treaty between Catherine and Joseph II — were already in preliminary development, and her earlier alliance with Prussia under Frederick the Great remained a cornerstone of Russian strategic positioning. The year 1777 represented a critical juncture in Catherine’s long-term strategy to weaken Ottoman power and establish Russian dominance over the Black Sea.
Catherine’s 1777 diplomacy operated amid the distraction of the American Revolutionary War, which consumed British and French resources and attention. Russia, though not a belligerent, benefited from this Anglo-French exhaustion: Catherine’s diplomatic initiatives faced fewer obstacles when European powers were committed elsewhere. Her court in Saint Petersburg maintained correspondence with Frederick II and Joseph II regarding the territorial disposition of Ottoman holdings. Most decisively, in 1777 Catherine’s government backed Shahin Giray’s installation as the last independent Crimean Khan — a political maneuver designed to transform Crimea into a Russian satellite before eventual annexation in 1783. Her 1777 maneuvering thus represented the opening moves of a long-term strategy that would culminate in Russia’s 1783 annexation of Crimea and the displacement of Ottoman power from the northern Black Sea coast.
The Crimean Question in 1777
The Crimean Peninsula had been a protectorate de facto since Russia’s victory in the First Russo-Turkish War, concluded by the Treaty of Küçük Kaynarca in July 1774. That treaty formally recognized Crimean independence from the Ottoman Empire — but in practice it left the peninsula contested between Ottoman and Russian influence. In 1777, Catherine’s government engineered the removal of Khan Devlet IV Giray, whom Ottoman agents backed, and installed Shahin Giray, a Westernized Crimean nobleman educated in Greece and Italy who favored Russian influence and attempted to modernize the Khanate’s institutions along European lines.
Shahin Giray’s installation in 1777 was a calculated gamble: his reformist policies — creating a European-style bureaucracy, reorganizing military forces, and limiting traditional Tatar nobility privileges — provoked widespread resistance within Crimea, generating exactly the social instability Catherine needed to justify future Russian military intervention. Shahin Giray himself applied to Catherine for military support to suppress revolts in 1777–1778, further binding Crimea to Russian protection. The arrangement demonstrated Catherine’s preferred method of expansion: cultivate a dependent client state, allow its internal contradictions to generate crises, then intervene under the guise of protecting stability. This pattern would be exploited to annex Crimea outright by April 1783.
Relations with Prussia and Austria
Frederick II of Prussia and Catherine II maintained the alliance framework established during the Seven Years’ War and the First Partition of Poland (1772). By 1777, however, the relationship had shifted: Frederick was aging (he would die in 1786 at age 74) and increasingly concerned with the Austrian succession following the death of Elector Maximilian III Joseph of Bavaria in December 1777. The resulting War of the Bavarian Succession (1778–1779, also called the Potato War) drew Frederick’s attention westward, which suited Catherine’s interests: a Prussia preoccupied with Central European succession disputes was less likely to interfere with Russian expansion toward the Black Sea.
Catherine’s diplomacy with Joseph II of Austria was similarly strategic. Joseph II became sole ruler following his mother Maria Theresa’s death in November 1780, but the groundwork for the 1781 Austro-Russian alliance was laid in earlier diplomatic exchanges. Catherine and Joseph met personally at Mogilev in 1780, but their correspondence and the reports of their ambassadors throughout 1777 established mutual interests in containing Ottoman power and managing Polish instability. For Catherine, Austria was a useful counterweight to potential Ottoman-Prussian coalitions and a partner in partitioning whatever Ottoman and Polish territories could be absorbed.
Internal Stability After the Pugachev Rebellion
Catherine’s 1777 diplomatic ambitions rested on an internal political foundation she had only recently secured. The Pugachev Rebellion (1773–1775), led by the Cossack Yemelyan Pugachev who claimed to be the murdered Tsar Peter III, had mobilized peasants, Cossacks, and non-Russian minorities across the Volga-Ural region in the largest popular uprising in Russian history before 1917. Pugachev’s army captured Kazan in July 1774 and threatened to march on Moscow before Catherine’s forces crushed the revolt; Pugachev himself was executed in Moscow on January 21, 1775.
By 1777, two years after the rebellion’s suppression, Catherine had drawn clear institutional lessons. She implemented the Guberniya Reform of 1775, reorganizing Russia’s provincial administration into 50 guberniyas each governed by appointed officials directly responsible to the central government — reducing the autonomy of regional nobles that had allowed the rebellion to spread unchecked. This administrative restructuring, still being implemented throughout 1777, made Russia’s internal governance more centralized and more capable of supporting sustained military operations abroad. A more stable and organized domestic administration was the prerequisite for the ambitious foreign policy Catherine pursued that year.
The League of Armed Neutrality
Catherine’s 1777 diplomacy also laid conceptual groundwork for the League of Armed Neutrality, which she formally proposed in February 1780. The League — eventually joined by Denmark, Sweden, Prussia, Austria, Portugal, and the Ottoman Empire — declared the principle of freedom of neutral shipping from belligerent interference, directly challenging Britain’s right to stop and search neutral vessels bound for France and Spain. The strategic concept emerged from Russia’s consistent 1777–1779 experience of British interference with Russian merchant shipping in the Baltic and North Sea. Catherine’s 1777 diplomatic instructions to her ambassadors in London and Paris already articulated the neutral rights position that the League would formalize, establishing her as the leading advocate of a new international maritime law framework that significantly constrained British naval power during the American Revolutionary War.
Significance
Catherine’s 1777 diplomacy shaped the geopolitical order that outlived the American Revolution itself. While France and Britain fought over colonial possessions in North America and the Caribbean, Catherine engineered a steady Russian expansion that ultimately redrew the map of Eastern Europe and Western Asia. Her diplomatic support for Shahin Giray in 1777 was the first move in a six-year sequence culminating in the formal annexation of Crimea on April 8, 1783 — a geopolitical alteration that transferred a strategically vital peninsula and its population from Ottoman to Russian sovereignty.
More broadly, Catherine’s diplomatic strategy during 1777 established the template for Russian imperial expansion that would dominate the remainder of the 18th century: cultivate local clients, manage European balance-of-power calculations, and consolidate control incrementally. Her 1777 initiatives were foundational to Russia’s emergence as a primary European power and to the Russian territorial expansion that created geopolitical tensions persisting into the modern era. The American Revolution distracted European power calculations in 1777; Catherine’s silent diplomacy reshaped them.
