The Migration Period (circa 300 to 600 AD), also known as the Barbarian Invasions, was a period in European history marked by large-scale migrations that saw the fall of the Western Roman Empire and subsequent settlement of its former territories by various tribes, and the establishment of the post-Roman kingdoms.
The term refers to the important role played by the migration, invasion, and settlement of various tribes, notably the Franks, Goths, Alemanni, Alans, Huns, early Slavs, Pannonian Avars, Bulgars and Magyars within or into the territories of the Roman Empire and Europe as a whole. The period is traditionally taken to have begun in AD 375 (possibly as early as 300) and ended in 568. Various factors contributed to this phenomenon of migration and invasion, and their role and significance are still widely discussed.
Historians differ as to the dates for the beginning and ending of the Migration Period. The beginning of the period is widely regarded as the invasion of Europe by the Huns from Asia in about 375 and the ending with the conquest of Italy by the Lombards in 568, but a more loosely set period is from as early as 300 to as late as 800. For example, in the 4th century a very large group of Goths was settled as foederati within the Roman Balkans, and the Franks were settled south of the Rhine in Roman Gaul. In 406 a particularly large and unexpected crossing of the Rhine was made by a group of Vandals, Alans and Suebi. As central power broke down in the Western Roman Empire, the military became more important but was dominated by men of barbarian origin.
There are contradictory opinions as to whether the fall of the Western Roman Empire was a result of an increase in migrations, or if both the breakdown of central power and the increased importance of non-Romans created additional internal factors. Migrations, and the use of non-Romans in the military, were known in the periods before and after, and the Eastern Roman Empire adapted and continued to exist until the fall of Constantinople to the Ottomans in 1453. The fall of the Western Roman Empire, although it involved the establishment of competing barbarian kingdoms, was to some extent managed by the Eastern emperors.
The migrants are thought to have comprised of war bands or tribes of 10,000 to 20,000 people. Immigration was common throughout the time of the Roman Empire, but over the course of 100 years, the migrants numbered not more than 750,000 in total, compared to an average 40 million population of the Roman Empire at that time. The first migrations of peoples were made by Germanic tribes such as the Goths (including the Visigoths and the Ostrogoths), the Vandals, the Anglo-Saxons, the Lombards, the Suebi, the Frisii, the Jutes, the Burgundians, the Alemanni, the Sciri and the Franks; they were later pushed westward by the Huns, the Avars, the Slavs and the Bulgars. Later invasions, such as the Vikings, the Normans, the Varangians, the Hungarians, the Arabs, the Turks, and the Mongols also had significant effects (especially in North Africa, the Iberian Peninsula, Anatolia and Central and Eastern Europe).
Germanic Tribes
Germanic peoples moved out of southern Scandinavia and northern Germany to the adjacent lands between the Elbe and Oder after 1000 BC. The first wave moved westward and southward (pushing the resident Celts west to the Rhine around 200 BC), moving into southern Germany up to the Roman provinces of Gaul and Cisalpine Gaul by 100 BC, where they were stopped by Gaius Marius and later by Julius Caesar. It is this western group which was described by the Roman historian Tacitus (AD 56–117) and Julius Caesar (100–44 BC). A later wave of Germanic tribes migrated eastward and southward from Scandinavia, between 600 and 300 BC, to the opposite coast of the Baltic Sea, moving up the Vistula near the Carpathian Mountains. During Tacitus’ era they included lesser-known tribes such as the Tencteri, Cherusci, Hermunduri and Chatti; however, a period of federation and intermarriage resulted in the familiar groups known as the Alemanni, Franks, Saxons, Frisians and Thuringians.
First wave
The first wave of invasions, between AD 300 and 500, is partly documented by Greek and Latin historians but is difficult to verify archaeologically. It puts Germanic peoples in control of most areas of what was then the Western Roman Empire.[12]
The Tervingi crossed the Danube into Roman territory in 376, in a migration fleeing the invading Huns. Some time later in Marcianopolis, the escort to their leader Fritigern was killed while meeting with Roman commander Lupicinus. The Tervingi rebelled, and the Visigoths, a group derived either from the Tervingi or from a fusion of mainly Gothic groups, eventually invaded Italy and sacked Rome in 410 before settling in Gaul. Around 460, they founded the Visigothic Kingdom in Iberia. They were followed into Roman territory first by a confederation of Herulian, Rugian, and Scirian warriors under Odoacer, that deposed Romulus Augustulus in 476, and later by the Ostrogoths, led by Theodoric the Great, who settled in Italy.
In Gaul, the Franks (a fusion of western Germanic tribes whose leaders had been aligned with Rome since the 3rd century) entered Roman lands gradually during the 5th century, and after consolidating power under Childeric and his son Clovis’s decisive victory over Syagrius in 486, established themselves as rulers of northern Roman Gaul. Fending off challenges from the Alemanni, Burgundians, and Visigoths, the Frankish kingdom became the nucleus of what would later become France and Germany.
The initial Anglo-Saxon settlement of Britain occurred during the 5th century, when Roman control of Britain had come to an end. Saxons, Angles and Jutes from Denmark and Northern Germany migrated to southern and eastern England. The Burgundians settled in northwestern Italy, Switzerland and Eastern France in the 5th century.
Second wave
Between AD 500 and 700, Slavic tribes settled more areas of central Europe and pushed farther into southern and eastern Europe, gradually making the eastern half of Europe predominantly Slavic.[15] Additionally, Turkic tribes such as the Avars and later Ugric Magyars became involved in this second wave. In AD 567, the Avars and the Lombards destroyed much of the Gepid Kingdom. The Lombards, a Germanic people, settled in Italy with their Herulian, Suebian, Gepid, Thuringian, Bulgar, Sarmatian and Saxon allies in the 6th century. They were later followed by the Bavarians and the Franks, who conquered and ruled most of Italy.
The Bulgars, originally a nomadic group probably from Central Asia, occupied the Pontic steppe north of Caucasus since the 2nd century, but later, pushed by the Khazars, the majority of them migrated west and dominated Byzantine territories along the lower Danube in the 7th century. From that time the demographic picture of the Balkans changed permanently, becoming predominantly Slavic, while pockets of native people survived in the mountains of the Balkans.
The Hungarian conquest of the Carpathian Basin from around AD 895 and the following Hungarian invasions of Europe and the Viking expansion from the late 8th century conventionally mark the last large movements of the period. Christian missionaries gradually converted the non-Islamic newcomers and integrated them into the Christendom.
During the early Byzantine–Arab Wars, Arab armies attempted to invade southeast Europe via Asia Minor during the late 7th and early 8th centuries but were defeated at the siege of Constantinople (717–718) by the joint forces of Byzantium and the Bulgars. During the Khazar–Arab Wars, the Khazars stopped the Arab expansion into Europe across the Caucasus (7th and 8th centuries). At the same time, the Moors (consisting of Arabs and Berbers) invaded Europe via Gibraltar (conquering Hispania from the Visigothic Kingdom in 711), before being halted by the Franks at the Battle of Tours in Gaul. These battles broadly demarcated the frontiers between Christendom and Islam for the next millennium. The following centuries saw the Muslims successful in conquering most of Sicily from the Christians by 902.
