Proclaimed emperor in 193 by his legionaries in Noricum during the political unrest that followed the death of Commodus, he secured sole rule over the empire in 197 after defeating his last rival, Clodius Albinus, at the Battle of Lugdunum. In securing his position as emperor, he founded the Severan dynasty.
Overwhelmed by the number of invasions and usurpers, Philip offered to resign, but the Senate decided to throw its support behind the emperor, with a certain Gaius Messius Quintus Decius most vocal of all the senators. Philip was so impressed by his support that he dispatched Decius to the region with a special command encompassing all of the Pannonian and Moesian provinces. This had a dual purpose of both quelling the rebellion of Pacatianus as well as dealing with the barbarian incursions. Although Decius managed to quell the revolt, discontent in the legions was growing. Decius was proclaimed emperor by the Danubian armies in the spring of 249 and immediately marched on Rome.
On the Danube, Scythian tribes were once again on the loose, despite the peace treaty signed in 251. They invaded Asia Minor by sea, burned the great Temple of Artemis at Ephesus, and returned home with the plunder. Lower Moesia was also invaded in early 253. Aemilianus, governor of Moesia Superior and Pannonia, took the initiative and defeated the invaders.
Sometime between 258 and 260 (the exact date is unclear), while Valerian was distracted with the ongoing invasion of Shapur I in the East, and Gallienus was preoccupied with his problems in the West, Ingenuus, governor of at least one of the Pannonian provinces, took advantage and declared himself emperor. Valerian II had apparently died on the Danube, most likely in 258. Ingenuus may have been responsible for Valerian II's death. Alternatively, the defeat and capture of Valerian at the battle of Edessa may have been the trigger for the subsequent revolts of Ingenuus, Regalianus, and Postumus.
In any case, Gallienus reacted with great speed. He left his son Saloninus as caesar at Cologne, under the supervision of Albanus (or Silvanus) and the military leadership of Postumus. He then hastily crossed the Balkans, taking with him the new cavalry corps (comitatus) under the command of Aureolus and defeated Ingenuus at Mursa or Sirmium. Ingenuus was killed by his own guards or committed suicide by drowning himself after the fall of his capital, Sirmium.
In the years 267–269, Goths and other barbarians invaded the empire in great numbers. Sources are extremely confused on the dating of these invasions, the participants, and their targets. Modern historians are not even able to discern with certainty whether there were two or more of these invasions or a single prolonged one. It seems that, at first, a major naval expedition was led by the Heruli starting from north of the Black Sea and leading to the ravaging of many cities of Greece (among them, Athens and Sparta). Then another, even more numerous army of invaders started a second naval invasion of the empire. The Romans defeated the barbarians on sea first. Gallienus' army then won a battle in Thrace, and the emperor pursued the invaders. According to some historians, he was the leader of the army who won the great Battle of Naissus, while the majority believes that the victory must be attributed to his successor, Claudius II.
However, he fell victim to the Plague of Cyprian (possibly smallpox) and died early in January 270. Before his death, he is thought to have named Aurelian as his successor, though Claudius' brother Quintillus briefly seized power.
When Claudius died, his brother Quintillus seized power with the support of the Senate. With an act typical of the Crisis of the Third Century, the army refused to recognize the new Emperor, preferring to support one of its own commanders: Aurelian was proclaimed emperor about May 270 by the legions in Sirmium.
Carus was apparently a senator and filled various posts, both civil and military, before being appointed prefect of the Praetorian Guard by the emperor Probus in 282. Two traditions surround his accession to the throne in August or September of 282. According to some mostly Latin sources, he was proclaimed emperor by the soldiers after the murder of Probus by a mutiny at Sirmium. Greek sources however claim that he rose against Probus in Raetia in usurpation and had him killed. Bestowing the title of Caesar upon his sons Carinus and Numerian, he left Carinus in charge of the western portion of the empire to look after some disturbances in Gaul and took Numerian with him on an expedition against the Persians, which had been contemplated by Probus.
Probus was eager to start his eastern campaign, delayed by the revolts in the west. He left Rome in 282, traveling first towards Sirmium, his birth city. Different accounts of Probus's death exist. According to Joannes Zonaras, the commander of the Praetorian Guard Marcus Aurelius Carus had been proclaimed, more or less unwillingly, emperor by his troops. Probus sent some troops against the new usurper, but when those troops changed sides and supported Carus, Probus' remaining soldiers assassinated him at Sirmium (September/October 282). According to other sources, however, Probus was killed by disgruntled soldiers, who rebelled against his orders to be employed for civic purposes, like draining marshes. Allegedly, the soldiers were provoked when they overheard him lamenting the necessity of a standing army. Carus was proclaimed emperor after Probus' death and avenged the murder of his predecessor.
The Plague of Justinian (541–542 AD) was a pandemic that afflicted the Byzantine (Eastern Roman) Empire and especially its capital, Constantinople, as well as the Sasanian Empire, and port cities around the entire Mediterranean Sea, as merchant ships harbored rats that carried fleas infected with plague. Some historians believe the plague of Justinian was one of the deadliest pandemics in history, resulting in the deaths of an estimated 25–50 million people during two centuries of recurrence, a death toll equivalent to 13–26% of the world's population at the time of the first outbreak.
By the mid-550s, Justinian had won victories in most theatres of operation, with the notable exception of the Balkans, which were subjected to repeated incursions from the Slavs and the Gepids. Tribes of Serbs and Croats were later resettled in the northwestern Balkans, during the reign of Heraclius. Justinian called Belisarius out of retirement and defeated the new Hunnish threat. The strengthening of the Danube fleet caused the Kutrigur Huns to withdraw and they agreed to a treaty that allowed safe passage back across the Danube.
Justin's successor, Tiberius II, choosing between his enemies, awarded subsidies to the Avars while taking military action against the Persians. Although Tiberius' general, Maurice, led an effective campaign on the eastern frontier, subsidies failed to restrain the Avars. They captured the Balkan fortress of Sirmium in 582, while the Slavs began to make inroads across the Danube.
The alliance of the Holy League pressed home the advantage of the defeat at Vienna, culminating in the Treaty of Karlowitz (26 January 1699), which ended the Great Turkish War. The Ottomans surrendered control of significant territories, many permanently.
After the Austro-Turkish War of 1716–1718, the Treaty of Passarowitz confirmed the loss of the Banat, Serbia, and "Little Walachia" (Oltenia) to Austria. The Treaty also revealed that the Ottoman Empire was on the defensive and unlikely to present any further aggression in Europe.
The Austro-Russian–Turkish War (1735–1739), which was ended by the Treaty of Belgrade in 1739, resulted in the Ottoman recovery of northern Bosnia, Habsburg Serbia (including Belgrade), Oltenia, and the southern parts of the Banat of Temeswar; but the Empire lost the port of Azov, north of the Crimean Peninsula, to the Russians. After this treaty, the Ottoman Empire was able to enjoy a generation of peace, as Austria and Russia were forced to deal with the rise of Prussia.
The Russo-Turkish War (1877–1878) ended with a decisive victory for Russia. As a result, Ottoman holdings in Europe declined sharply: Bulgaria was established as an independent principality inside the Ottoman Empire; Romania achieved full independence, and Serbia and Montenegro finally gained complete independence, but with smaller territories.
Archaeological finds have produced a large number of cauldrons that have since the work of Paul Reinecke in 1896 been identified as having been produced by the Huns. Although typically described as "bronze cauldrons". the cauldrons are often made of copper.
Serbia decreed general mobilization on the 25th. Serbia accepted all of the terms of the ultimatum except for article six, which demanded that Austrian delegates be allowed in Serbia for the purpose of participation in the investigation into the assassination. Following this, Austria broke off diplomatic relations with Serbia and, the next day, ordered a partial mobilization.
The Battle of Cer was a military campaign fought between Austria-Hungary and Serbia in August 1914, starting three weeks into the Serbian Campaign, the initial military action of the First World War. It took place around Cer Mountain and several surrounding villages, as well as the town of Šabac. The battle was a part of the first Austro-Hungarian invasion of Serbia, began on the night of 15 August when elements of the Serbian 1st Combined Division encountered Austro-Hungarian outposts that had been established on the slopes of Cer Mountain earlier in the invasion. The clashes that followed escalated into a battle for control over several towns and villages near the mountain, especially Šabac.
Faced with Russia in the east, Austria-Hungary could spare only one-third of its army to attack Serbia. After suffering heavy losses, the Austrians briefly occupied the Serbian capital, Belgrade. A Serbian counter-attack in the Battle of Kolubara succeeded in driving them from the country by the end of 1914. For the first ten months of 1915, Austria-Hungary used most of its military reserves to fight Italy.
On 13 November, Károlyi signed an armistice with the Allied nations in Belgrade. It limited the size of the Hungarian army to six infantry and two cavalry divisions. Demarcation lines defining the territory to remain under Hungarian control were made.
The Yugoslav government was overthrown two days later (Tripartite Pact Signature) by nationalists. The Yugoslav coup d'état of 27 March 1941 in Belgrade, Kingdom of Yugoslavia, replaced the regency led by Prince Paul and installed King Peter II.
Yugoslavia and Greece were invaded in April 1941 and surrendered before the end of the month. Germany and Italy divided Greece into occupation zones but did not eliminate it as a country. The key areas of Central Macedonia, Athens, and Thessaloniki were occupied by Germany while others by Italians and parts by Bulgarian forces.
On 17 April 1941, after King Peter II and other members of the government fled the country, the remaining representatives of the government and military met with the German officials in Belgrade.
Despite conflicts with the rival monarchic Chetnik movement, Tito's Partisans succeeded in liberating territory, notably the "Republic of Užice". During this period, Tito held talks with Chetnik leader Draža Mihailović on 19 September and 27 October 1941.
On 7 March 1945, the provisional government of the Democratic Federal Yugoslavia (Demokratska Federativna Jugoslavija, DFY) was assembled in Belgrade by Josip Broz Tito, while the provisional name allowed for either a republic or monarchy.
Prime Minister Josip Broz Tito met with the president of the Bishops' Conference of Yugoslavia, Aloysius Stepinac on 4 June 1945, two days after his release from imprisonment. The two could not reach an agreement on the state of the Catholic Church. Under Stepinac's leadership, the bishops' conference released a letter condemning alleged Partisan war crimes in September 1945.
n 1952, following pressure from Tesla's nephew, Sava Kosanović, Tesla's entire estate was shipped to Belgrade in 80 trunks marked N.T. In 1957, Kosanović's secretary Charlotte Muzar transported Tesla's ashes from the United States to Belgrade. The ashes are displayed in a gold-plated sphere on a marble pedestal in the Nikola Tesla Museum.
In the same year, Tito became active in promoting a peaceful resolution of the Arab–Israeli conflict. His plan called for Arabs to recognize the state of Israel in exchange for territories Israel gained.
In 1974 Kosovo's political status improved further when a new Yugoslav constitution granted an expanded set of political rights. Along with Vojvodina, Kosovo was declared a province and gained many of the powers of a fully-fledged republic: a seat on the federal presidency and its own assembly, police force and national bank.
In the late 1980s, Milošević allowed the mobilization of Serb nationalist organizations to go unhindered by actions from the Serbian government, with Chetniks holding demonstrations, and the Serbian government embracing the Serbian Orthodox Church and restored its legitimacy in Serbia.
Provincial power was still exercised by the Communist Party, but now devolved mainly to ethnic Albanian communists. Tito's death on 4 May 1980 ushered in a long period of political instability, worsened by growing economic crisis and nationalist unrest.
In 1981 it was reported that some 4,000 Serbs moved from Kosovo to central Serbia after the Kosovo Albanian riots in March that resulted in several Serb deaths and the desecration of Serbian Orthodox architecture and graveyards.
The first major outbreak occurred in Kosovo's main city, Pristina, when a protest of University of Pristina students over long queues in their university canteen rapidly escalated and in late March and early April 1981 spread throughout Kosovo, causing mass demonstrations in several towns. The disturbances were quelled by the Presidency of Yugoslavia proclaiming a state of emergency, sending in riot police and the army, which resulted in numerous casualties.
In February 1982 a group of priests from Serbia proper petitioned their bishops to ask "why the Serbian Church is silent" and why it did not campaign against "the destruction, arson and sacrilege of the holy shrines of Kosovo". Such concerns did attract interest in Belgrade. Stories appeared from time to time in the Belgrade media claiming that Serbs and Montenegrins were being persecuted.
The sixth UN conference on trade and development in Belgrade, 6–30 June 1983 was held against the background of earlier UNCTADs which have substantially failed to resolve many of the disagreements between the developed and developing countries and of a world economy in its worst recession since the early 1930s. The key issues of the time were finance and adjustment, commodity price stabilization, and trade.
