Prussian BerlinWilhelmstraße · 13 June – 13 July 1878

Twenty sittings in Bismarck’s palace redrew the Balkans — and kept the great powers from war over them for thirty-six years

Between 13 June and 13 July 1878, 20 plenipotentiaries of seven powers met on the Wilhelmstraße and rewrote the peace Russia had dictated at San Stefano. They cut its Greater Bulgaria in three and gave Bosnia to Austria-Hungary. No Balkan state signed the treaty.

01The Reichstag, 19 February 1878

Berlin got the Congress because its host claimed to want nothing

In the Reichstag on 5 December 1876 Bismarck said he would not advise any active German part in the Eastern crisis while no German interest was at stake “worth the healthy bones of a single Pomeranian musketeer”. Fourteen months later, with a Russian army before Constantinople, he offered Germany a different part:

“…in the role of an honest broker, who desires to bring the affair to a favorable end.”Bismarck in the Reichstag, 19 February 1878, as the US legation translated it

Vienna could not host a congress — Austria-Hungary was one of Russia’s likely enemies — and London, Constantinople and St Petersburg were out for the same reason. Berlin, the historian Imanuel Geiss wrote for the Federal Agency for Civic Education, was the capital of the great power with no direct interests of its own in the Balkans. The Congress sat in the Reichskanzlerpalais, the chancellor’s official residence, newly moved into.

02From the war to the table

Fourteen months from a declaration of war to a congress

Russia’s war against the Ottoman Empire ended in a peace that Britain and Austria-Hungary refused to accept. The Congress was how Europe avoided a second war over the first.

A British fleet, and an “honest broker”

In February 1878 Britain sent its fleet into the Bosporus as a counterweight to the Russian troops. On 19 February 1878 Bismarck offered to act as an honest broker.

At San Stefano, on 3 March 1878, Russia dictated the peace. It drew a Greater Bulgaria reaching the Aegean and the gates of Adrianople and Constantinople. Britain readied an expeditionary corps of 70,000 men.

Vienna proposes Berlin

On 7 March 1878 Austria-Hungary proposed a European congress at Berlin. Russia took the idea up in mid-April. Its ambassador in London, Count Shuvalov, agreed to make Bulgaria smaller and divide it.

3 June 1878

Three deals in four days

Germany sent out the invitations on 3 June 1878, the day after the second attempt on Wilhelm I’s life. On 4 June Britain won the right to occupy Cyprus if Russia kept Batum. On 6 June it agreed with Austria-Hungary to make Bulgaria smaller and divide it.

On 13 June 1878 the Congress met in the Reichskanzlerpalais: 20 plenipotentiaries of seven powers, with Bismarck in the chair. On questions of substance, decisions had to be unanimous.

0313 June – 13 July 1878

Twenty sittings in thirty-one days — and eleven of them crammed into the last thirteen

The protocols record 20 plenary sittings. Bismarck kept pushing the pace. In June the Congress sat 9 times in 18 days; in July it sat 11 times in 13, twice on 6 July.

At the start, a quarrel over Bulgaria between Britain and Russia brought the Congress to the edge of breaking up, with war in the air. Bismarck saved it outside the plenary, in private talks with the two chief delegates, Gorchakov and Beaconsfield. The sittings then recorded what had been settled.

“This impatience of the Chancellor’s, justified by his state of health, speeds the work along, but its drawbacks will be felt later, because much will have been settled only superficially. I would rather work more slowly.”Prince Hohenlohe, Germany’s third plenipotentiary, in his diary, 5 July 1878

04Werner’s painting, 1881

The famous picture shows a handshake — not the men who fought hardest

The city of Berlin commissioned Anton von Werner to paint the final sitting of 13 July 1878 and approved 60,000 marks for it. He presented the canvas, 6.15 m wide, on 22 March 1881, the Kaiser’s 84th birthday. At its centre Bismarck shakes hands not with Gorchakov, Russia’s chancellor, but with his deputy Shuvalov — the man who had agreed in London to cut Bulgaria down. Gorchakov resented Shuvalov’s good relations with Bismarck, GHDI notes; Werner seats him at the edge. The picture, Geiss wrote, is a stylised record of the signature. Tap the numbers.

Each power sent three plenipotentiaries, Italy two: 20 men, named in the treaty’s preamble. France came with no claim in the Balkans, but asked on the margins for compensation for Cyprus. It got it three years later, when it made Tunis a protectorate.

05The Treaty of Berlin, 13 July 1878

Bulgaria filled the first twenty-two of the treaty’s sixty-four articles

The quarrel was Bulgaria, so the treaty began there. Article I made it “an autonomous and tributary Principality under the suzerainty” of the Sultan, north of the Balkan range. Article XIII formed a province south of the range, Eastern Roumelia, under the Sultan’s direct authority with a Christian governor-general. The rest of San Stefano’s Bulgaria, in Macedonia, went back to the Sultan.

The 64 articles in order, by subject

Single articles: XXII Russian occupation of both · XXIII Crete and Turkey in Europe · XXIV Greece’s frontier · XXV Bosnia-Herzegovina, Novi Pazar · LXII Religious liberty in Turkey.

Art. XXV

Austria-Hungary: Bosnia and Herzegovina, without a war of its own

Article XXV: the provinces “shall be occupied and administered by Austria-Hungary”, with garrisons in the Sanjak of Novi Pazar. The Congress overrode every protest from the people of the two provinces. Austria-Hungary needed almost 200,000 men to force the occupation through.

Art. XLIII, XLIV, XLV, XLVI

Romania: independent, on conditions — and short of Bessarabia

Articles XLIII–XLVI: Romania’s independence was recognised on condition that no one be excluded from civil or political rights because of their religion. The clause was meant for Romania’s Jews, and the government evaded it after the Congress. Romania gave back to Russia the strip of Bessarabia that Russia had lost in 1856, and received the Danube delta and the Dobruja.

Convention of 4 June 1878

Britain: Cyprus, outside the treaty

Cyprus appears nowhere in the treaty. A secret convention of 4 June 1878 let Britain occupy and govern the island, which stayed Ottoman in name. Britain annexed it formally in 1914, at the start of the First World War.

061878–1914

It kept the great powers from war over the Balkans for thirty-six years. Then the Bosnian fuse burned through

Disraeli came home to cheering crowds in London and declared “peace with honour”. Geiss judged that the Congress more than met its short-term aim. It decided the provinces’ futures “in the style of old cabinet politics”, without regard for the right of nations to self-determination.

Bulgaria and Eastern Roumelia united on their own in 1885. A year after the Congress, Germany and Austria-Hungary formed the Dual Alliance (1879). Austria-Hungary’s occupation of Bosnia later became annexation. The resistance it bred produced, a generation later, the assassins of Sarajevo.

The Congress of Berlin · 1878

Europe’s great powers kept the peace among themselves by dividing the Balkans in a Berlin palace, in a treaty no Balkan state signed. The bill came due in Sarajevo.

Corrected from our earlier sheet

  • Bismarck’s “honest broker” was a Reichstag speech of 19 February 1878, not a circular to the powers. Austria-Hungary proposed Berlin as the venue, and Germany’s invitation followed on 3 June 1878.
  • The plenipotentiaries are those the treaty names. The sheet listed four men who were not among them and left out seven who were.
  • Disraeli attended from the first sitting, on 13 June 1878, not from later in June.
  • San Stefano’s Bulgaria reached the Aegean, but it did not cover most of the Balkan peninsula.
  • The British fleet entered the Bosporus in February 1878, not January.
  • The sheet’s story of Bismarck refusing to speak English and Disraeli refusing French, and its archive signatures, could not be traced to any source; they are left out.
  • Two cartoons on the sheet are not about the Congress at all: one is about the Anti-Socialist Law, the other about Bismarck and the Pope.
