The city (then mostly known as Plevna outside Bulgaria) was a major battle scene during the Russo-Turkish War of 1877–1878 that Russian Tsar Alexander II held for the purpose of the liberation of Bulgaria. The joint Russian and Romanian army paid dearly for the victory, but it paved the path to the defeat of the Ottoman Empire in this war, the restoration of Bulgaria as a state and the independence of Romania from the Ottoman Empire. It cost the Russians and Romanians 5 months and 38,000 casualties to take the town after four assaults, in what was one of the decisive battles of the war. The siege is remembered as a landmark victory of the Romanian War of Independence, as on 28 November 1877 the Plevna citadel capitulated, and Osman Pasha surrendered the city, the garrison and his sword to the Romanian Colonel Mihail Cerchez.
