Pannonia in the context of "Republic of Serbia"

The First Bulgarian Empire (Church Slavonic: блъгарьско цѣсарьствиѥ, romanized: blŭgarĭsko tsěsarǐstvije; Bulgarian: Първо българско царство) was a medieval state that existed in Southeastern Europe between the 7th and 11th centuries AD. It was founded in 680–681 after part of the Bulgars, led by Asparuh, moved south to the northeastern Balkans. There they secured Byzantine recognition of their right to settle south of the Danube by defeating – possibly with the help of local South Slavic tribes – the Byzantine army led by Constantine IV. During the 9th and 10th century, Bulgaria at the height of its power spread from the Danube Bend to the Black Sea and from the Dnieper River to the Adriatic Sea and became an important power in the region competing with the Byzantine Empire.

As the state solidified its position in the Balkans, it entered into a centuries-long interaction, sometimes friendly and sometimes hostile, with the Byzantine Empire. Bulgaria emerged as Byzantium's chief antagonist to its north, resulting in several wars. The two powers also enjoyed periods of peace and alliance, most notably during the Second Arab Siege of Constantinople, where the Bulgarian army broke the siege and destroyed the Arab army, thus preventing an Arab invasion of Southeastern Europe. Byzantium had a strong cultural influence on Bulgaria, which also led to the eventual adoption of Christianity in 864. After the disintegration of the Avar Khaganate, the country expanded its territory northwest to the Pannonian Plain. Later the Bulgarians confronted the advance of the Pechenegs and Cumans, and achieved a decisive victory over the Magyars, forcing them to establish themselves permanently in Pannonia.

Trajan (/ˈtreɪdʒən/ TRAY-jən; born Marcus Ulpius Traianus, 18 September 53 – c. 9 August 117) was a Roman emperor from AD 98 to 117, remembered as the second of the Five Good Emperors of the Nerva–Antonine dynasty. He was a philanthropic ruler and a successful soldier-emperor who presided over one of the greatest military expansions in Roman history, during which, by the time of his death, the Roman Empire reached its maximum territorial extent. He was given the title of Optimus ('the best') by the Roman Senate.

Trajan was born in the municipium of Italica in the present-day Andalusian province of Seville in southern Spain, an Italic settlement in Hispania Baetica; his gens Ulpia came from the town of Tuder in the Umbria region of central Italy. His namesake father, Marcus Ulpius Traianus, was a general and distinguished senator. Trajan rose to prominence during the reign of Domitian; in AD 89, serving as a legatus legionis in Hispania Tarraconensis, he supported the emperor against a revolt on the Rhine led by Antonius Saturninus. He then served as governor of Germania and Pannonia. In September 96, Domitian was succeeded by the elderly and childless Nerva, who proved to be unpopular with the army. After a revolt by members of the Praetorian Guard, Nerva decided to adopt as his heir and successor the more popular Trajan, who had distinguished himself in military campaigns against Germanic tribes.

The Scordisci (Ancient Greek: Σκορδίσκοι; Latin: Scordiscii, Scordistae) were an Iron Age cultural group who emerged after the Celtic settlement of Southeast Europe, and who were centered in the territory of present-day Serbia, at the confluence of the Savus (Sava), Dravus (Drava), Margus (Morava) and Danube rivers. They were historically notable from the beginning of the third century BC until the turn of the common era, and consolidated into a tribal state. At their zenith, their core territory stretched over regions comprising parts of present-day Serbia, Croatia, Bulgaria and Romania, while their influence spread even further. After the Roman conquest in the 1st century AD, their territories were included into the Roman provinces of Pannonia, Moesia and Dacia.

The Pannonian Basin, with the term Carpathian Basin being sometimes preferred in Hungarian literature, is a large, mainly lowland area in southeastern Central Europe, briefly described as a sedimentary basin. Under the geopolitically changed conditions created by World War I and the ensuing Treaty of Trianon, the geomorphological term Pannonian Plain was also used for roughly the same region, referring to the lowlands in the area occupied by the Pannonian Sea during the Pliocene. However, Hungarian geographers consider the term "Pannonian Plain" not only unhistorical but also topographically highly erroneous. Regarding the name as such, they are arguing in terms of ancient history, namely that the northern and eastern boundary line of the namesake Roman province of Pannonia was formed by the River Danube, thus the Great Hungarian Plain was not part of the original Pannonia province.

Gallic groups, originating from the various La Tène chiefdoms, began a southeastern movement into the Balkans from the 4th century BC. Although Gallic settlements were concentrated in the western half of the Carpathian basin, there were notable incursions and settlements within the Balkans.

From their new bases in northern Illyria and Pannonia, the Gallic invasions climaxed in the early 3rd century BC, with the invasion of Greece. The 279 BC invasion of Greece proper was preceded by a series of other military campaigns waged in the southern Balkans and against the Kingdom of Macedonia, favoured by the state of confusion ensuing from the disputed succession after Alexander the Great's death. A part of the invading Celts crossed over to Anatolia and eventually settled in the area that came to be named after them, Galatia.

The Boii (Latin plural, singular Boius; Ancient Greek: Βόιοι) were a Celtic tribe of the later Iron Age, attested at various times in Cisalpine Gaul (present-day Northern Italy), Pannonia (present-day Austria and Hungary), present-day Bavaria, in and around present-day Bohemia (after whom the region is named in most languages; comprising the bulk of today's Czech Republic), parts of present-day Slovakia and Poland, and Gallia Narbonensis (located in modern Languedoc and Provence).

In addition, the archaeological evidence indicates that in the 2nd century BC Celts expanded from Bohemia through the Kłodzko Valley into Silesia, now part of Poland and the Czech Republic.

The pileus (Ancient Greek: πῖλος, pîlos; also pilleus or pilleum in Latin) was a brimless felt cap worn in Ancient Greece, Etruria, Illyria (especially Pannonia), later also introduced in Ancient Rome. The pileus also appears on Apulian red-figure pottery.

The pilos together with the petasos were the most common types of hats in Archaic and Classical era (8th–4th century BC) Greece. In the 5th century BC, a bronze version began to appear in Ancient Greece and it became a popular infantry helmet. It occasionally had a horsehair crest. The Greek pilos resembled the Roman and Etruscan pileus, which were typically made of felt. The Greek πιλίδιον (pilidion) and Latin pilleolus were smaller versions, similar to a skullcap.

Romulus Augustus (c. 460-465) – (c. 511-530), nicknamed Augustulus, was Roman emperor of the West from 31 October 475 until 4 September 476. Romulus was placed on the imperial throne while still a minor by his father Orestes, the magister militum, for whom he served as little more than a figurehead. After a rule of ten months, the barbarian general Odoacer defeated and killed Orestes and deposed Romulus. As Odoacer did not proclaim any successor, Romulus is typically regarded as the last Western Roman emperor, his deposition marking the end of the Western Roman Empire as a political entity. The deposition of Romulus Augustulus is also sometimes used by historians to mark the transition from antiquity to the medieval period.

Very few records survive of Romulus's reign. There are no known policies, laws or inscriptions of significance of the emperor, which leaves the impression that he was a shadowy and relatively inconsequential figure. The nickname "Augustulus" means "little Augustus" and was a derisive reference to his young age. Romulus's immediate family, including his father and possibly his mother, and maybe both his paternal and maternal grandparents, were from the Roman province of Pannonia, and many of his family members had military backgrounds.

The Vandals were a Germanic people who were first mentioned in the written records as the inhabitants of what is now Poland, during the period of the Roman Empire. Much later, in the 5th century, a group of Vandals led by kings established Vandal kingdoms, first within the Iberian Peninsula, and then in the western Mediterranean islands and North Africa.

Archaeologists associate the early Vandals with the Przeworsk culture, which has led to some authors equating them to the Lugii, who were another group of Germanic peoples associated with that same archaeological culture and region. Expanding into Dacia during the Marcomannic Wars and into Pannonia during the Crisis of the Third Century, the Vandals were confined to Pannonia by the Goths around 330 AD, where they received permission to settle from Constantine the Great. Around 400, raids by the Huns from the east forced many Germanic tribes to migrate west into the territory of the Roman Empire and, fearing that they might be targeted next, the Vandals were also pushed westwards, crossing the Rhine into Gaul along with other tribes in 406. In 409, the Vandals crossed the Pyrenees into the Iberian Peninsula, where the Hasdingi and the Silingi settled in Gallaecia (northwest Iberia) and Baetica (south-central Iberia).
