Barbarian invasions in the context of "Republic of Italy"

Italy, officially the Italian Republic, is a country in Southern and Western Europe. It consists of a peninsula that extends into the Mediterranean Sea, with the Alps on its northern land border, as well as nearly 800 islands, notably Sicily and Sardinia. Italy shares land borders with France to the west; Switzerland and Austria to the north; Slovenia to the east; and the two enclaves of Vatican City and San Marino. It is the tenth-largest country in Europe by area, covering 301,340 km (116,350 sq mi), and the third-most populous member state of the European Union, with nearly 59 million inhabitants. Italy's capital and largest city is Rome; other major cities include Milan, Naples, Turin, Palermo, Bologna, Florence, Genoa, and Venice.

The history of Italy goes back to numerous Italic peoples – notably including the ancient Romans, who conquered the Mediterranean world during the Roman Republic and ruled it for centuries during the Roman Empire. With the spread of Christianity, Rome became the seat of the Catholic Church and the Papacy. Barbarian invasions and other factors led to the decline and fall of the Western Roman Empire between late antiquity and the Early Middle Ages. By the 11th century, Italian city-states and maritime republics expanded, bringing renewed prosperity through commerce and laying the groundwork for modern capitalism. The Italian Renaissance flourished during the 15th and 16th centuries and spread to the rest of Europe. Italian explorers discovered new routes to the Far East and the New World, contributing significantly to the Age of Discovery.

The High Middle Ages, or High Medieval Period, was the period of European history between c. 1000 and c. 1300; it was preceded by the Early Middle Ages and followed by the Late Middle Ages, which ended c. 1500 according to historiographical convention. Key historical trends of the High Middle Ages include the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, and the Renaissance of the 12th century, including the first developments of the rural exodus and urbanization. By 1350, the robust population increase had greatly benefited the European economy, which had reached levels that would not be seen again in some areas until the 19th century. That trend faltered in the early 14th century, as the result of numerous events which together comprised the crisis of the late Middle Ages—most notable among them being the Black Death, in addition to various regional wars and economic stagnation.

From c. 780, Europe saw the last of the barbarian invasions and became more socially and politically organized. The Carolingian Renaissance stimulated scientific and philosophical activity in Northern Europe. The first universities started operating in Bologna, Oxford, Paris, Salamanca, Cambridge and Modena. The Vikings settled in the British Isles, France and elsewhere, and Norse Christian kingdoms started developing in their Scandinavian homelands. The Magyars ceased their expansion in the 10th century, and by 1000, a Christian Kingdom of Hungary had become a recognized state in Central Europe that was forming alliances with regional powers. With the brief exception of the Mongol invasions in the 13th century, major nomadic incursions ceased. The powerful Byzantine Empire of the Macedonian and Komnenos dynasties gradually gave way to the resurrected Serbia and Bulgaria and to a successor crusader state (1204 to 1261), who continually fought each other until the end of the Latin Empire. The Byzantine Empire was reestablished in 1261 with the recapture of Constantinople from the Latins, though it was no longer a major power and would continue to falter through the 14th century, with remnants lasting until the mid 15th century.

In historiography, the Late or Later Roman Empire, traditionally covering the period from 284 CE to 641 CE, was a time of significant transformation in Roman governance, society, and religion. Diocletian's reforms, including the establishment of the tetrarchy, aimed to address the vastness of the empire and internal instability. The rise of Christianity, legalized by Constantine the Great in 313 CE, profoundly changed the religious landscape, becoming a central force in Roman life. Simultaneously, barbarian invasions, particularly by the Goths and the Huns, weakened the Western Roman Empire, which collapsed in 476 CE. In contrast, the Eastern Roman Empire endured, evolving into the Byzantine Empire and laying the foundations for medieval Europe.

Dalmatian city-states were formerly Roman municipalities in Dalmatia where the local Romance population survived the Barbarian invasions after the fall of the Western Roman Empire in the 400s CE. Eight little cities were created by the indigenous Illyro-Roman inhabitants of the region, who maintained political links with the Eastern Roman Empire, which in return defended these cities, enabling their commercial trade with Byzantium.

The original names of these city-states were Arba, Cattarum, Crespa, Jadera, Ragusium, Spalatum, Tragurium, and Vecla. The language and the laws were initially Latin, but after a few centuries, they developed their own vulgar Latin language, Dalmatian, which survived into the 19th century. The cities were maritime centers with important commerce links, mainly with the Italian Peninsula and with the rising Republic of Venice.

The Battle of Ravenna, capital of the Western Roman Empire, between the Heruli under their King Odoacer and the remnants of the Western Roman army in Roman Italy occurred in early September 476, and represented a culminating event in the ongoing fall of the Western Roman Empire. The Western Roman Empire had been in relative decline since the beginning of the barbarian invasions and Rome, the symbolical heart and largest city of the Western Empire, was sacked in 410 by the Visigoths and in 455 by the Vandals. By 476 the Roman emperor was little more than a puppet, having very little de facto control of any territory outside of Italy. The last Roman emperor, Romulus Augustulus, was not recognized as a legitimate ruler outside of Italy; the Eastern Roman Empire recognized Julius Nepos as the true Western Roman Emperor.

Herulians were foederati of the Western Roman Empire; they were mercenary troops of the Roman army of Italy. They envied the fortune of their brethren in Gaul, Spain, and Africa, whose victorious arms had acquired an independent and perpetual inheritance; and they insisted that a third part of the lands of Italy should be immediately divided among them. Orestes, the father of emperor Romulus Augustus, rejected their demand – causing their revolt. From all the camps and garrisons of Italy the confederates flocked to the standard of Odoacer, their leader; Orestes later retreated to Pavia. Pavia was subsequently pillaged and Orestes was executed.
