The Crimean War was fought between Russia and an alliance of the Ottoman Empire, France, the United Kingdom, and Sardinia from October 1853 to February 1856. Geopolitical causes of the war included the Eastern question (the decline of the Ottoman Empire), the expansion of Russia in the preceding Russo-Turkish wars, and the British and French preference to preserve the Ottoman Empire to maintain the balance of power in the Concert of Europe.
The war's proximate cause was Tsar Nicholas I's demand that the Ottoman Empire's Orthodox subjects be placed under his protection. After the Sublime Porte's refusal, Russian troops occupied the Danubian Principalities in July 1853. The Ottomans declared war on Russia in October. Fearing the growth of Russian influence and compelled by public outrage over the annihilation of the Ottoman squadron at Sinop, Britain and France joined the war on the Ottoman side in March 1854. The Russian advance was halted at Silistria in June.
In September 1854, after extended preparations, allied forces landed in Crimea in an attempt to capture Russia's main naval base in the Black Sea, Sevastopol. They scored an early victory at the Battle of the Alma. The Russians counterattacked in late October in what became the Battle of Balaclava and were repulsed, and a second counterattack at Inkerman ended in a Russian defeat. The front settled into the 11-month Siege of Sevastopol, involving brutal conditions for troops on both sides. Smaller military actions took place in the Caucasus (1853–1855), the White Sea (July–August 1854) and the North Pacific (1854–1855). The Kingdom of Sardinia-Piedmont entered on the allies' side in 1855.
Sevastopol ultimately fell after a renewed French assault on the Malakoff redoubt in September 1855. Diplomatically isolated and facing the prospect of invasion from the west if the war continued, Russia sued for peace in March 1856. France and Britain welcomed the development due to the conflict's domestic unpopularity. The Treaty of Paris, signed on 30 March 1856, ended the war. It forbade Russia from basing warships in the Black Sea. The Ottoman vassal states of Wallachia and Moldavia became largely independent. Christians in the Ottoman Empire gained a degree of official equality, and the Orthodox Church regained control of the Christian churches in dispute.
The Crimean War was one of the first conflicts in which military forces used modern technologies such as explosive naval shells, railways, and telegraphs. It was also one of the first to be documented extensively in written reports and in photographs. The war quickly symbolised logistical, medical and tactical failures and mismanagement. The reaction in Britain led to a demand for the professionalisation of medicine, most famously achieved by Florence Nightingale, who gained worldwide attention for pioneering modern nursing while she treated the wounded.
The Crimean War also marked a turning point for the Russian Empire. It weakened the Imperial Russian Army, drained the treasury, and undermined its influence in Europe. The defeat forced Russia's educated elites to identify the country's fundamental problems. It became a catalyst for reforms of Russia's social institutions, including the emancipation reform of 1861, which abolished serfdom in Russia, and overhauls in the justice system, local self-government, education, and military service.
Eastern question
As the Ottoman Empire steadily weakened during the 19th century, the Russian Empire stood poised to take advantage by expanding southward. In the 1850s, the British and the French Empires were allied with the Ottoman Empire and were determined to prevent that from happening.Matthew Smith Anderson, The Eastern Question, 1774–1923: A Study in International Relations. p. 37. The historian A. J. P. Taylor argued that the war had resulted not from aggression, but from the interacting fears of the major players:
Background Weakening of the Ottoman Empire: 1820–1840s In the early 1800s, the Ottoman Empire suffered a number of existential challenges. The Serbian Revolution in 1804 resulted in the autonomy of the first Balkan Christian nation under the empire. The Greek War of Independence, which began in early 1821, provided further evidence of the empire's internal and military weakness, and the commission of atrocities by Ottoman military forces (see Chios massacre) further undermined the empire. The disbandment of the centuries-old Janissary corps by Sultan Mahmud II on 15 June 1826 (Auspicious Incident) helped the empire in the longer term but deprived it of its existing standing army in the short term. In 1827, the Anglo-Franco-Russian fleet destroyed almost all of the Ottoman naval forces at the Battle of Navarino. In 1830, Greece became independent after ten years of war and the Russo-Turkish War (1828–29). The Treaty of Adrianople (1829) granted Russian and Western European commercial ships free passage through the Black Sea straits. Also, the Danubian Principalities (Moldavia and Wallachia) became territories under Russian protection.
France took the opportunity to occupy Algeria, which had been under Ottoman rule, in 1830. In 1831, Muhammad Ali of Egypt, the most powerful vassal of the Ottoman Empire, declared independence. Ottoman forces were defeated in a number of battles, which forced Mahmud II to seek Russian military aid. A Russian army of 10,000 landed on the shores of the Bosphorus in 1833 and helped prevent the Egyptians from capturing Constantinople.
"The reasons for the Tsar's disquietude are not obscure. It was not just Turkey that was threatened by the advance of Ibrahim. The rights secured to Russia by a succession of treaties were also directly jeopardized. The substitution of a virile Albanian dynasty at Constantinople in place of the effete Osmanlis was the last thing desired by the Power which wished, naturally enough, to command the gate into the Mediterranean". Russia was satisfied with the weak government in Constantinople (Istanbul).
As a result, the Treaty of Hünkâr İskelesi was signed and greatly benefited Russia. It provided for a military alliance between the Russian and the Ottoman Empires if one of them was attacked, and a secret additional clause allowed the Ottomans to opt out of sending troops but to close the Straits to foreign warships if Russia were under threat. Egypt remained nominally under Ottoman sovereignty but was de facto independent.
In 1838 in a situation similar to that of 1831, Muhammad Ali of Egypt was not happy about his lack of control and power in Syria, and he resumed military action. The Ottomans lost to the Egyptians at the Battle of Nezib on 24 June 1839 but were saved by Britain, Austria, Prussia and Russia, who signed a convention in London on 15 July 1840 that granted Muhammad Ali and his descendants the right to inherit power in Egypt in exchange for the removal of Egyptian forces from Syria and Lebanon. Moreover, Muhammad Ali had to admit a formal dependence on the Ottoman sultan. After Muhammad Ali refused to obey the requirements of the convention, the allied Anglo-Austrian fleet blockaded the Nile Delta, bombarded Beirut and captured Acre. Muhammad Ali then accepted the convention's conditions.
On 13 July 1841, after the expiry of the Treaty of Hünkâr İskelesi, the London Straits Convention was signed under pressure from the European countries. The new treaty deprived Russia of its right to block warships from passing into the Black Sea in case of war. Thus, the way to the Black Sea was open for British and French warships during a possible Russo-Ottoman conflict.
Russian historians tend to view that history as evidence that Russia lacked aggressive plans. The Russian historian V. N. Vinogradov writes: "The signing of the documents was the result of deliberate decisions: instead of bilateral (none of the great powers recognized this Treaty of Unkiar Skelessi), the new Treaty of London was obligatory for all, it closed the Bosphorus and Dardanelles. In the absence of expansion plans, this was a sound decision".
In 1838, Britain lost interest in crushing the Ottoman Empire. On the contrary, after the conclusion of the trade treaty of 1838 (see Treaty of Balta Liman), Britain received unlimited access to the markets of the Ottoman Empire. "Britain imposed on the Porte a Tariff Convention which in effect transformed the Ottoman Empire into a virtual free-trade zone. Therefore its trade interests pushed it to protect the integrity of the Ottoman Empire. In the long term, the Ottoman Empire lost the opportunity to modernize and industrialise, but in the short term, it gained the opportunity to receive the support of European powers (primarily Britain) in opposing the desire of the conquered peoples for self-determination and Russia, which sought to crush its influence in the Balkans and Asia.
Publicly, European politicians made broad promises to the Ottomans. Lord Palmerston, the British Foreign Secretary, said in 1839: "All that we hear about the decay of the Turkish Empire, and its being a dead body or a sapless trunk, and so forth, is pure and unadulterated nonsense. Given 10 years of peace under European protection, coupled with internal reform, there seemed to him no reason why it should not become again a respectable Power".
Orlando Figes has claimed that "The motives of the British in promoting liberal reforms were not just to secure the independence of the Ottoman Empire against Russia. They were also to promote the influence of Britain in Turkey", also: "to promote British free-trade interests (which may have sounded splendid but was arguably damaging to the Ottoman Empire)".
"British exports to the Ottoman Empire, including Egypt and the Danubian principalities, increased nearly threefold from 1840 to 1851 (...) Thus it was very important, from the financial point of view, for Britain to prevent the Ottoman Empire from falling into other hands."
"From this moment (1838) the export of British manufactured goods to Turkey rose steeply. There was an elevenfold increase by 1850".
Assistance from Western European powers or Russia had twice saved the Ottoman Empire from destruction, but the Ottomans also lost their independence in foreign policy. Britain and France desired more than any other states to preserve the integrity of the Ottoman Empire because they did not want to see Russia gaining access to the Mediterranean Sea. Austria had the same fears.
Russian expansionism
Russia, as a member of the Holy Alliance, had operated as the "police of Europe" to maintain the balance of power that had been established in the Congress of Vienna in 1815. Russia had assisted Austria's efforts in suppressing the Hungarian Revolution of 1848, and expected a free hand in settling its problems with the Ottoman Empire, the "sick man of Europe". However, Britain could not tolerate Russian dominance of Ottoman affairs, which would challenge its domination of the eastern Mediterranean.
Starting with Peter the Great in the early 1700s, after centuries of Ottoman northward expansion and Crimean-Nogai raids, Russia began a southwards expansion across the sparsely populated "Wild Fields" toward the warm water ports of the Black Sea, which do not freeze over, unlike the handful of ports controlled by Russia in the north. The goal was to promote year-round trade and a year-round navy. Pursuit of that goal brought the emerging Russian state into conflict with the Zaporozhian Cossacks along the lower reaches of the Dnieper River and then the Tatars of the Crimean Khanate and Circassians.
"The plan to develop Russia as a southern power had begun in earnest in 1776, when Catherine placed Potemkin in charge of New Russia (Novorossiya), the sparsely populated territories newly conquered from the Ottomans on the Black Sea's northern coastline, and ordered him to colonize the area".
