The April Uprising (Bulgarian: Априлско въстание, romanized: Aprilsko vastanie) was an insurrection organised by the Bulgarians in the Ottoman Empire from April to May 1876. The rebellion was suppressed by irregular Ottoman bashi-bazouk units that engaged in indiscriminate slaughter of both rebels and non-combatants (see Batak massacre).
The American community around Robert College in Istanbul, the Protestant mission in Plovdiv headed by J.F. Clarke as well as two other Americans, journalist Januarius MacGahan and diplomat Eugene Schuyler, were indispensable in bringing knowledge of Ottoman atrocities to the wider European public.
Their reports of the events, which came to be known in the press as the Bulgarian Horrors and the Crime of the Century, caused a public outcry across Europe and mobilised both common folks and famous intellectuals to demand a reform of the failed Ottoman model of governance of the Bulgarian lands.
The shift in public opinion, in particular, in the Ottoman Empire's hitherto closest ally, the British Empire, eventually led to the re-establishment of a separate Bulgarian state in 1878.
In Europe, in the 18th century, the classic non-national states were the multi-ethnic empires such as the Ottoman Empire and the Austro-Hungarian Empire, whose population belonged to many ethnic groups and spoke many languages. The idea of nation state became more prominent during the 19th century. The most noticeable characteristic was the degree to which nation states used the state as an instrument of national unity in economic, social and cultural life. By the 18th century, the Ottomans had fallen well behind the rest of Europe in science, technology, and industry. However, the Bulgarian population was also suppressed socially and politically under Ottoman rule. Additionally, more immediate causes for the greater mobilisation compared to earlier revolts were the severe internal and external problems which the Ottoman Empire experienced in the middle of the 1870s. In 1875, taxes levied on non-Muslims were raised for fear of state bankruptcy, which, in turn, caused additional tension between Muslims and Christians and led to the Herzegovinian rebellion and the Stara Zagora revolt in Bulgaria. The failure of the Ottomans to handle the Herzegovinian uprising successfully showed the weakness of the Ottoman state, and the atrocities committed during its suppression discredited it internationally. In the late 19th century, European ideas of nationalism were adopted by the Bulgarian elite.
In November 1875, activists of the Bulgarian Revolutionary Central Committee met in the Romanian town of Giurgiu and decided that the political situation was suitable for a general uprising. The uprising was scheduled for April or May 1876. The territory of the country was divided into five revolutionary districts with centers in Vratsa (leader-Stoyan Zaimov), Veliko Tarnovo (Stefan Stambolov), Sliven (Ilarion Dragostinov), Plovdiv (Panayot Volov—who later gave his position to his assistant Georgi Benkovski) and Sofia (Nikola Obretenov).
The rebels had been hoarding arms and ammunition for some time and even constructed a makeshift cannon out of cherry-wood.
In the progress of the preparation of the uprising, the organisers gave up the idea of a fifth revolutionary district in Sofia due to the deplorable situation of the local revolutionary committees and moved the centre of the fourth revolutionary district from Plovdiv to Panagyurishte. On 14 April 1876, a general meeting of the committees from the fourth revolutionary district was held in the Oborishte locality near Panagyurishte to discuss the proclamation of the insurrection. However, one of the delegates disclosed the plot to the Ottoman authorities. As a result, the Ottoman police made an attempt to arrest the leader of the local revolutionary committee in Koprivshtitsa, Todor Kableshkov on 2 May [O.S. 20 April] 1876.
The Bulgarian Revolutionary Central Committee's minutes from 17th of April 1876 chaired by Benkovski discuss retaliation against the Turkish and Muslim population in mixed regions opposing the uprising. These actions include killing, arson of property and homes and seizure of assets. On the other hand, Muslims who did not resist were to be protected in the same way as the Bulgarian population. The committee also gave approval for torching towns and villages. However, there is no evidence that this plan was implemented.
In conformity with the decisions taken at Oborishte, the local rebel committee attacked and surrounded the headquarters of the Ottoman police in Koprivshtitsa on 20 April 1876. At least two Ottoman police officers were killed, and the commander, Necip Aga, was forced to release arrested rebel suspects. Necip Aga and his close officials managed to escape the siege. However, due to this incident, the Bulgarian rebels had to proclaim the insurrection two weeks in advance of the planned date.
Within several days, the rebellion spread to the entire Sredna Gora and to a number of towns and villages in the northwestern Rhodopes. The insurrection broke out in the other revolutionary districts, though on a much smaller scale. The areas of Gabrovo, Tryavna, and Pavlikeni also revolted in force, along with several villages north and south of Sliven and near Berovo (in present-day North Macedonia).
The Ottoman response was immediate and severe. Irregular bashi-bazouks, sometimes accompanied by army detachments, were swiftly mobilized. These forces attacked the first insurgent towns as early as 25 April. The Ottomans massacred civilian populations, the principal places being Panagurishte, Perushtitza, Klisura, and Batak (see Batak massacre). By the middle of May, the insurrection was completely suppressed. One of the last sparks of resistance was poet Hristo Botev's attempt to come to the rebels' rescue with a detachment of Bulgarian political émigrés resident in Romania, which ended with the unit's rout and Botev's death.
Nevertheless, a unit of Circassian paramilitaries managed to commit a final atrocity well after the end of hostilities. They butchered 145 non-combatants at Boyadzhik after confusing the preparation for a Bulgarian holiday with a rebellion in the making.
The Porte's refusal to send additional regular army detachments, and the decision of the Beys of Edirne and Filibe to instead arm bashi-bazouk forces greatly determined the number of casualties and the aftermath of the uprising's suppression. Thus, the village of Bratsigovo, which was one of the best prepared centres of the rebellion and managed to fiercely resist enemy attacks for days, suffered only 250 casualties, very few of whom civilian, after fighting a regular Ottoman army unit. The leader of the Bratsigovo resistance, Vasil Petleshkov, also assumed all blame for what had happened. By contrast, Perushtitza, Panagurishte and Batak, which faced bashi-bazouk forces, all suffered enormous casualties, estimated by Schuyler at approx. 1,000, 3,000 and 5,000, respectively.
Schuyler qualified the uprising as poorly prepared and undeserving of the brutality of the Ottoman response. Modern Bulgarian historiography also calls it premature and poorly prepared and considers that the organisers only wanted to draw European and Russian public attention to the plight of Ottoman Bulgarians, with no illusions that the revolt would succeed.
In view of the poor preparation of the insurgents, but the enormous repercussions of their deeds, American Protestant missionary and author Henry Otis Dwight called the revolt "the maddest freak that ever led men to death".
The most detailed contemporary account of the uprising was prepared by American diplomat Eugene Schuyler. He learned about the events from faculty members at Robert College, who feared that the coming investigation of Englishman Walter Baring would turn into a cover-up because of the British Empire's strongly pro-Ottoman official stance and his own reputation as a Turkophile.
After visiting 3 cities and 11 villages, Schuyler compiled a report detailing the burning of sixty-five villages, the demolition of five monasteries and the slaughter of at least 15,000 people—rebels and non-combatants alike. However, what Schuyler emphasised the most was the exceptional, highly unnecessary brutality employed, in particular, at Batak. Eventually, despite his reputation as a Turkophile, Baring by and large confirmed Schuyler's findings. The report of his investigation only reduced the estimated number of victims to 12,000.
