Ancient Times
Pliny, Appian and Ptolemy mentioned the Docleatae as living in the maritime region, holding the town of Doclea (old Podgorica). In 9 AD the Romans conquered the region. Slavs colonized the area in the 6th century, and had by the 10th century formed a semi-independent principality called Duklja in suzerainty to the Byzantine Empire.
Middle Ages
Duklja gained its independence from the Byzantine Roman Empire in 1042. Over the next few decades, it expanded its territory to neighbouring Rascia and Bosnia and also became recognised as a kingdom. Its power started declining at the beginning of 12th century. After King Bodin’s death(in 1101 or 1108) several civil wars ensued. As the nobility fought for the throne the kingdom was weakened and by 1186 it was conquered by Stefan Nemanja and incorporated into Serbian realm as a province named Zeta. After the Serbian Empire collapsed in the second half of the 14th century, the most powerful Zetan family, the Balšićs, became sovereigns of Zeta.
Ottoman rule and Metropolitanate
In the 16th century Montenegro developed a form of unique autonomy within the Ottoman Empire with Montenegrin clans being free from certain restrictions. Nevertheless the Montenegrins refused to accept Ottoman rule and in the 17th century raised numerous rebellions, culminating with the defeat of the Ottomans in the Great Turkish War at the end of that century.
Principality of Montenegro
Under Nicholas I, the Principality was enlarged several times in the Montenegro-Turkish Wars and was recognised as independent in 1878. Under the rule of Nicholas I, diplomatic relations were established with the Ottoman Empire. Minor border skirmishes excepted, diplomacy ushered in approximately 30 years of peace between the two states until the deposition of Abdul Hamid II. During this period, one of the major Montenegrin victories over the Ottomans occurred at the Battle of Grahovac. Grand Duke Mirko Petrović, elder brother of Knjaz Danilo. The glory of Montenegrin victory was soon immortalized in the songs and literature of all the South Slavs, in particular the Montenegrins in Vojvodina, then part of Austria-Hungary. This forced the Great Powers to officially demarcate the borders between Montenegro and Ottoman Empire, de facto recognizing Montenegro’s independence. Montenegro’s independence was recognized by Ottoman Empire at Treaty of Berlin in 1878.The first Montenegrin constitution was proclaimed in 1855; it was also known as the Danilo Code.
Kingdom of Montenegro (1910–1918)
In 1910 Montenegro became a Kingdom and as a result of the Balkan wars in 1912 and 1913 (in which the Ottomans lost all Balkan land), a common border with Serbia was established, with Shkodër being awarded to a newly created Albania, even though the current capital city of Montenegro, Podgorica was the old border of Albania and Yugoslavia. In World War I in 1914 Montenegro sided with Serbia against the Central Powers, suffering a full-scale defeat to Austria-Hungary in early 1916. In 1918 the Allies liberated Montenegro, which was subsequently merged with Serbia.During World War I (1914–1918) Montenegro was allied with the Allied Powers. From 15 January 1916 to October 1918, Montenegro was occupied by Austria-Hungary. During occupation, King Nicholas fled first to Italy and then to France, and the government transferred its operations to Bordeaux. When the Allies liberated Montenegro, thePodgorica Assembly was convened and voted to ban the king from returning and to unite the country with the Kingdom of Serbia on 1 December 1918. In the Christmas Uprising, a large part of the Montenegrin population,[citation needed] known as the Greens, rebelled against this decision to unify with Serbia and, led by captain Krsto Zrnov Popović, fought against the pro-unification forces, Whites.The royal family was rehabilitated in 2011, by the government and today is headed by Crown Prince Nicholas II who has his own foundation.
Kingdom of Montenegro (1941–1944)
In 1941, Benito Mussolini occupied Montenegro and annexed it to the Kingdom of Italy. The Queen of Italy, Elena of Montenegroinfluenced her husband Victor Emmanuel III to suggest that Mussolini make Montenegro independent of Yugoslavia. After the spring of 1942, much of the Sandžak region, which was included in the state of Montenegro, was not actually controlled by its government. The area of the Bay of Kotor (the Venetian Cattaro) was annexed to the Dalmatian province of Italy until September 1943. After the departure of the Italians, Montenegro remained under the direct control of German troops, with a terrible and bloody guerrilla war ravaging the area. In December 1944 the German troops withdrew and Josip Broz Tito’s Partisans assumed control.President Berisha and his Democratic Party pushed hard for radical reforms to create a market economy and democratic institutions internally, while bringing Albania back into the international mainstream after half a century of isolation.
