Congress of Berlin in the context of "Balkan Wars"

Montenegro is a country in Southeast Europe, on the Balkan Peninsula. Its 25 municipalities have a total population of 633,158 people in an area of 13,883 km (5,360 sq mi). It is bordered by Serbia to the northeast, Bosnia and Herzegovina to the northwest, Kosovo to the east, Albania to the southeast, and Croatia to the west, and has a coastline along the Adriatic Sea to the southwest. The capital and largest city is Podgorica, while Cetinje is the Old Royal Capital and cultural centre.

Before the arrival of the Slav peoples in the Balkans in the 6th and 7th centuries CE, the area now known as Montenegro was inhabited principally by people known as Illyrians.During the Early Medieval period, three principalities were located on the territory of modern-day Montenegro: Duklja, roughly corresponding to the southern half; Travunia, the west; and Rascia proper, the north. The Principality of Zeta emerged in the 14th and 15th centuries. From the late 14th century to the late 18th century, large parts of southern Montenegro were ruled by the Venetian Republic and incorporated into Venetian Albania. The name Montenegro was first used to refer to the country in the late 15th century. After falling under Ottoman Empire rule, Montenegro gained semi-autonomy in 1696 under the rule of the House of Petrović-Njegoš, first as a theocracy and later as a secular principality. Montenegro's independence was recognised by the Great Powers at the Congress of Berlin in 1878. In 1910, the country became a kingdom. After World War I, the kingdom became part of Yugoslavia. Following the breakup of Yugoslavia, the republics of Serbia and Montenegro together proclaimed a federation. In June 2006 Montenegro declared its independence following a referendum.

The Treaty of Berlin (formally the Treaty between Austria-Hungary, France, Germany, Great Britain and Ireland, Italy, Russia, and the Ottoman Empire for the Settlement of Affairs in the East) was signed on 13 July 1878. In the aftermath of the Russian victory against the Ottoman Empire in the Russo-Turkish War of 1877–1878, the major powers restructured the map of the Balkan region. They reversed some of the extreme gains claimed by Russia in the preliminary Treaty of San Stefano, but the Ottomans lost their major holdings in Europe. It was one of three major peace agreements in the period after the 1815 Congress of Vienna. It was the final act of the Congress of Berlin (13 June – 13 July 1878) and included the United Kingdom, Austria-Hungary, France, Germany, Italy, Russia and the Ottoman Empire. Chancellor of Germany Otto von Bismarck was the chairman and dominant personality.

The most important task of the Congress was to decide the fate of Bulgaria, but Bulgaria itself was excluded from participation in the talks, at Russian insistence. At the time, as it was not a sovereign state, Bulgaria was not a subject of international law, and the same went for the Bulgarians themselves. The exclusion was already an established fact in the great powers' Constantinople Conference, which had been held one year before without any Bulgarian participation.

The Principality of Bulgaria (Bulgarian: Княжество България, romanized: Knyazhestvo Balgariya) was a vassal state under the suzerainty of the Ottoman Empire. It was established by the Treaty of Berlin in 1878.

After the Russo-Turkish War ended with a Russian victory, the Treaty of San Stefano was signed by Russia and the Ottoman Empire on 3 March 1878. Under this, a large Bulgarian vassal state was agreed to, which was significantly larger: its lands encompassed nearly all ethnic Bulgarians in the Balkans, and included most of Moesia, Thrace and Macedonia, stretching from the Black Sea to the Aegean. However, the United Kingdom and Austria-Hungary were against the establishment of such a large Russian client state in the Balkans, fearing it would shift the balance of power in the Mediterranean. Due to this, the great powers convened and signed the Treaty of Berlin, superseding the Treaty of San Stefano, which never went into effect. This created a much smaller principality, alongside an autonomous Eastern Rumelia within the Ottoman Empire.

The Cyprus Convention of 4 June 1878 was a secret agreement reached between the United Kingdom and the Ottoman Empire which granted administrative control of Cyprus to Britain (see British Cyprus), in exchange for its support of the Ottomans during the Congress of Berlin. Provisions in the Convention retained Ottoman rights over the territory of Cyprus.

This agreement was the result of secret negotiations that took place earlier in 1878. The Convention was abrogated by the British on 5 November 1914, when Britain and the Ottoman Empire found themselves at war with each other following the Ottoman entry into World War I.

Serbs of Bosnia and Herzegovina or Bosnian Serbs, are one of the three constituent peoples of Bosnia and Herzegovina. According to data from the 2013 census, the population of ethnic Serbs in Bosnia and Herzegovina was 1,086,733, constituting 30.8% of the total population; they are the second-largest ethnic group in the country (after Bosniaks) and live predominantly in the political-territorial entity of Republika Srpska.

Serbs have a long history of inhabiting the present-day territory of Bosnia and Herzegovina as well as long history of statehood in that territory. Slavs settled the Balkans in the 6th century and the Serbs were one of the main tribes who settled the peninsula including parts of modern-day Bosnia and Herzegovina. Parts of Bosnia were ruled by the Serbian prince Časlav in the 10th century while the southeastern and eastern parts became integrated into the Serbian medieval state under the Nemanjić dynasty by the 13th-14th centuries. After the Ottoman conquest of Bosnia and Herzegovina, the majority of the Orthodox Christian population in the region retained their Serbian ethnic and religious identity under the restored Serbian Patriarchate of Peć, while many landowners converted to Islam. Throughout the period of Ottoman rule, the Serbs of Bosnia and Herzegovina, formed the core of several major uprisings against Ottoman rule. In 1878, following the Congress of Berlin, Austria-Hungary occupied Bosnia and Herzegovina, facing resistance from the Serb population, which increasingly aspired to unification with the Kingdom of Serbia, culminating in growing tensions that contributed to the assassination of Archduke Franz Ferdinand in Sarajevo, which triggered the World War I.

Bosnia and Herzegovina fell under Austro-Hungarian rule in 1878, when the Congress of Berlin approved the occupation of the Bosnia Vilayet, which officially remained part of the Ottoman Empire. Three decades later, in 1908, Austria-Hungary provoked the Bosnian crisis by formally annexing the occupied zone, establishing the Condominium of Bosnia and Herzegovina under the joint control of Austria and Hungary.

The Second Serbian Uprising was the second phase of the Serbian Revolution against the Ottoman Empire, which erupted shortly after the re-annexation of the country to the Ottoman Empire in 1813. The occupation was enforced following the defeat of the First Serbian Uprising (1804–1813), during which Serbia existed as a de facto independent state for over a decade. The second revolution ultimately resulted in Serbian semi-independence from the Ottoman Empire. The Principality of Serbia was established, governed by its own parliament, constitution and royal dynasty. De jure independence, however, was attained in 1878, following the decisions of the Congress of Berlin.
