Crimean War

Lore & Background

The war's proximate cause was Tsar Nicholas I's demand that Ottoman Orthodox subjects be placed under his protection. The Russian advance was halted at Silistria in June. They won at the Battle of the Alma, repulsed Russian counterattacks at Balaclava and Inkerman, and then settled into the 11-month Siege of Sevastopol. Smaller actions occurred in the Caucasus, White Sea, and North Pacific.

The Crimean War marked a turning point for the Russian Empire, weakening its army, draining its treasury, and undermining its influence in Europe. For Britain, the war's logistical and medical failures led to demands for professionalization of medicine, famously achieved by Florence Nightingale. The war was one of the first conflicts documented extensively in written reports and photographs, and it introduced modern technologies such as explosive naval shells, railways, and telegraphs. The Treaty of Paris forbade Russia from basing warships in the Black Sea, granted independence to Ottoman vassal states Wallachia and Moldavia, and gave Christians in the Ottoman Empire a degree of official equality.

Diplomatic Foundations and the Black Sea Question

Before a single shot was fired, Russia had spent years weaving a diplomatic web that left the Ottoman Empire increasingly isolated. Beneath these tactical moves lay a deeper, decades-long ambition: Russia's persistent struggle to gain meaningful access to the Black Sea. By the time hostilities erupted, Russia had successfully constrained its adversary on multiple axes, setting the stage for a multi-theater war stretching from the Black Sea littoral through the Caucasus and into the Balkans.

The 1736 Crimean Campaign and Its Devastating Toll

The war's opening blow struck the Crimean Tatars with extraordinary force but at a staggering human cost. The Tatar khans proved unable to mount a coherent defense. Over the following months, Russian expeditionary forces pushed deep into the peninsula, driving Tatar nobility into the hills and forcing Khan Fetih II Giray to flee to sea. Gozlev, Karasubazar, and the khan's palace in Bakhchysarai were set ablaze. Yet the campaign's true adversary proved to be disease rather than the Tatars.

The Habsburg Front and the Plague Years

Habsburg forces initially made headway in Ottoman Serbia, capturing Niš and inspiring a pro-Habsburg Serbian uprising against Ottoman rule. Russia was forced to abandon its positions at Ochakov and Kinburn due to the outbreak. In a remarkable footnote to the conflict, an Ottoman Muslim account translated by C. Fraser described Bosnian Muslim women taking up arms at the siege of Osterwitch-atyk fortress and in the defense of Būzin and Chetin, their bravery also noted in a French source. The war ground into a costly stalemate, with both sides exhausted by disease and supply shortages.

The 1739 Finale and the Treaty of Belgrade

The final year brought both dramatic Russian advances and a chaotic Habsburg collapse. His advance units, led by the young Constantine Cantemir, reached Iași, capital of Moldavia, by 12 September. Münnich entered the city on 14 September and pressed the Moldavian boyars to accept Russian annexation by 16 September. Simultaneously, the main Habsburg army suffered a strategic defeat at the Battle of Grocka near Belgrade on 21–22 July. Field Marshal Wallis retreated into Belgrade Fortress as the Turks laid siege. Vienna stripped Wallis of his negotiation powers and dispatched count Neipperg, who on 1 September signed a preliminary peace ceding Belgrade, unaware that Vienna had reversed its position. The Treaty of Belgrade, signed 18 September, confirmed Habsburg loss of Oltenia, central Serbia including Belgrade, and the Bosnian section of Posavina. A separate Russo-Turkish preliminary peace was negotiated through the French mediator marquis de Villeneuve.
