Russo-Turkish War (1735–1739)

Russo-Turkish War (1735–1739) was a significant conflict fought between the Russian Empire and the Ottoman Empire, with the Habsburg monarchy joining the war as an ally of Russia in 1737. The war was largely instigated by Russia's continued expansionist ambitions in the Black Sea region and recurring raids by the Crimean Khanate, an Ottoman vassal. Despite some initial Russian successes, the war concluded with the Treaty of Belgrade, which largely favored the Ottoman Empire and forced Austria to make significant territorial concessions.

Background

The war's origins are deeply intertwined with the broader Great Game of Europe and Russia's persistent drive for a warm-water port on the Black Sea. The immediate pretext was provided by repeated raids into Russian territory by the Crimean Tatars of the Crimean Khanate. Furthermore, Russia sought to capitalize on Ottoman involvement in a concurrent war with Safavid Iran, seeing a moment of potential weakness. The diplomatic landscape was also shaped by the War of the Polish Succession, where Russia and Austria were allied in support of Augustus III against the French-backed Stanisław Leszczyński. This alliance paved the way for later Austrian entry into the conflict against the Porte.

The course of the war

Hostilities began in 1735 with a Russian campaign aimed at the Crimean Khanate. In 1736, the army of Field Marshal Burkhard Christoph von Münnich successfully stormed the key fortress of Perekop and briefly occupied the Crimean capital of Bakhchysarai. Simultaneously, another army under Peter Lacy captured the vital fortress of Azov. However, these gains proved difficult to sustain due to severe logistical problems, disease, and relentless harassment by Crimean Tatar cavalry, forcing repeated retreats. The following years saw a shift in focus to Moldavia and Wallachia. In 1737, Münnich captured the strategic fortress of Ochakiv, but a failed siege of the Danube fortress of Bender in 1738 highlighted the ongoing challenges of campaigning deep in Ottoman territory.

Austrian intervention and the Treaty of Belgrade

The Habsburg monarchy, honoring its alliance with Russia, declared war on the Ottoman Empire in 1737. The Austrian campaign, however, was disastrous. Commanded by Francis Stephen of Lorraine and later George Olivier Wallis, Austrian forces suffered a catastrophic defeat at the Battle of Grocka in 1739. This defeat, coupled with the looming threat of a French diplomatic intervention on behalf of the Ottoman Empire, compelled Austria to seek a separate peace. The Treaty of Belgrade (1739) was highly favorable to the Porte. Austria was forced to cede Serbia (including Belgrade), Bosnia, and Oltenia (Little Wallachia) back to the Ottoman Empire. Russia, now isolated, was compelled to sign its own treaty at Niš, relinquishing all conquests except Azov, which was returned in a demilitarized state.

Aftermath and consequences

The war was a severe setback for the Habsburg monarchy, diminishing its prestige and influence in the Balkans for decades. For Russia, the results were mixed; while it failed to achieve its strategic goals in the Black Sea, it demonstrated its growing military capability and retained a foothold at Azov. The conflict solidified the Ottoman Empire's military reputation temporarily, but it also revealed the continuing threat posed by Russia. The war directly influenced the subsequent Russo-Turkish War of 1768–1774, where Catherine II would achieve the decisive victories that eluded Empress Anna. The diplomatic maneuvers, particularly by France's ambassador Louis Sauveur Villeneuve, underscored the complex European power dynamics surrounding the Eastern Question.
