In short
Russia and its Balkan allies fought the Ottoman Empire from 1877 to 1878 to reclaim territory lost in the Crimean War and support Christian populations under Ottoman rule. The conflict turned on the brutal Russian siege of the fortress town of Plevna in Bulgaria, which held out for five months before falling in December 1877. The Ottoman defeat hastened the empire's decline and redrew the map of southeastern Europe, establishing independent or autonomous Balkan states.
How it unfolded.
The five-minute version
What actually happened.
The Russo-Turkish War (1877–1878) was a conflict between the Ottoman Empire and a coalition led by the Russian Empire which included Romania, Serbia, and Montenegro. Precipitating factors included the Russian goals of recovering territorial losses endured during the Crimean War of 1853–1856, re-establishing itself in the Black Sea and supporting the political movement attempting to free Balkan nations from the Ottoman Empire. In Romania the war is called the Russo-Romanian-Turkish War (1877–1878) or the Romanian War of Independence (1877–1878).

Afterward
What followed
- 1878 - Congress of Berlin. Otto von Bismarck chaired the conference (June 13–July 13, 1878) that revised San Stefano. Partitioned Bulgaria, gave Cyprus to Britain, and prevented Russian domination of the Balkans-a major diplomatic defeat for Russian expansionism.
- 1878 - Ottoman loss of Balkans. Ottoman Empire ceded approximately 20% of its remaining territory in Europe. Macedonia, Albania, and Bosnia-Herzegovina remained under Ottoman nominal control but faced increasing Austro-Hungarian and nationalist pressure over the next three decades.
- 1878 - Treaty of San Stefano. Russia and Ottoman Empire agreed preliminary peace terms on March 3, 1878. Created autonomous Bulgaria under Russian influence, transferred Kars and Ardahan to Russia, and granted independence to Serbia, Romania, and Montenegro.
- 1880 - Emergence of the Eastern Question. The unresolved partition of Ottoman territories hardened European great-power rivalries. Austria-Hungary's occupation of Bosnia-Herzegovina (formalized 1908) and ongoing Balkan nationalism set the stage for regional instability leading to 1914.
- 1890 - Russian strategic stalemate. Despite military victory, Russian gains were diplomatically reversed at Berlin. The failure to establish a compliant Bulgaria and permanent Balkan hegemony redirected Russian focus eastward toward Manchuria, contributing to the Russo-Japanese War (1904–1905).

Same week, elsewhere
The 1877 war dominated European press and political discourse. The Ottoman military's stubborn defense of Plevna under Osman Pasha commanded international respect and coverage in The Times, Le Figaro, and Neue Freie Presse. British public opinion split between pro-Ottoman Tories (Disraeli's cabinet) and pro-Russian Liberals; Gladstone's 1876 pamphlet 'Bulgarian Horrors and the Question of the East' had already inflamed debate over Ottoman atrocities. Romantic imagery of Balkan liberation movements saturated European literature and art.
