Kofun (古墳 , from Sino-Japanese "ancient grave") are megalithic tombs or tumuli in Japan, constructed between the early 3rd century and the early 7th century AD.
 The term Kofun is the origin of the name of the Kofun period, which indicates the middle 3rd century to early-middle 6th century.
 Many Kofun have distinctive keyhole-shaped mounds (zenpō-kōen fun (前方後円墳 ) ), which are unique to ancient Japan.
 The Mozu-Furuichi kofungun or tumulus clusters have been proposed for inscription on the UNESCO World Heritage List, while Ishibutai Kofun is one of a number in Asuka-Fujiwara similarly residing on the Tentative List.
Scythian Neapolis (Greek: Σκυθική Νεάπολις ) was a settlement that existed from the end of the 3rd century BC until the second half of the 3rd century AD.
 The archeological ruins sit on the outskirts of the present-day Simferopol.
 This city was the center of the Crimean Scythian tribes, led by Skilurus and Palacus (who were probably buried at the local mausoleum).
 The town ruled over a small kingdom, covering the lands between the lower Dnieper river and Crimea.
 In the 3rd and 2nd centuries BC, it was a city "with a mixed Scythian-Greek population, strong defensive walls and large public buildings constructed using the orders of Greek architecture".
 Neapolis was destroyed halfway through the 3rd century AD by the Goths.
Germanic names, inherited from the Suevi (who settled in Galicia and northern Portugal in 409 AD), Visigoths, Vandals, Franks and other Germanic peoples, were the most common Galician names during the early and high Middle Ages.
 This article deals with Germanic personal names recorded and used in Galicia, northern Portugal and its adjoining regions: territories of the kingdom of the Suebi during the early Middle Ages from its 409 settlement to the 12th century.
The Early Middle Ages (or early medieval period), lasting from the 5th to the 10th century CE, marked the start of the Middle Ages of European history.
 The Early Middle Ages followed the decline of the Western Roman Empire and preceded the High Middle Ages (c. 10th to 13th centuries).
 The Early Middle Ages largely overlap with Late Antiquity.
 The term "Late Antiquity" is used to emphasize elements of continuity with the Roman Empire, while "Early Middle Ages" is used to emphasize developments characteristic of the later medieval period.
The history of the Netherlands is the history of seafaring people thriving on a lowland river delta on the North Sea in northwestern Europe.
 Records begin with the four centuries during which the region formed a militarized border zone of the Roman empire.
 This came under increasing pressure from Germanic peoples moving westwards.
 As Roman power collapsed and the Middle Ages began, three dominant Germanic peoples coalesced in the area, Frisians in the north and coastal areas, Low Saxons in the northeast, and the Franks in the south.
According to archaeological evidence, the Rhine-Weser Germanic or Weser-Rhine Germanic peoples were Germanic tribes whose settlement area in Roman times lay between the River Weser and the Middle Rhine although, later, during the Migration Period, they migrated southwest before reaching the border of the Roman Empire on the Rhine.
 This relatively recent term is based on archaeological finds dating to the 1st to 4th century AD, which can be roughly divided into five or six groups and identified as Germanic.
 From a comparison of archaeological evidence with ancient Roman writings, the Rhine-Weser Germanii included the Cherusci and Chatti as well as a number of smaller tribes, which are named by Roman sources and located in this region: the Usipetes, Tencteri, Sicambri, Bructeri, Chattuarii, Chamavi and Ampsivarii.
 Thus, the Rhine-Weser Germanii represent the group from which the Franks came later.
 The archaeological finds for the Rhine-Weser Germanii suggest they were the same tribal grouping as that referred to in the writings of Pliny the Elder and Tacitus as the Istvaeones (Istriones).
Old Norse religion developed from early Germanic religion during the Proto-Norse period, when the North Germanic peoples separated into a distinct branch of the Germanic peoples.
 It was displaced by Christianization of the North Germanic peoples.
 Scholars reconstruct aspects of North Germanic religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet.
 Numerous Old Norse works dated to the 13th century record Norse mythology, a component of North Germanic religion.
The Franks (Latin: "Franci" or "gens Francorum ") were a collection of Germanic peoples that originated in the lands between the Lower and Middle Rhine in the 3rd century AD and eventually formed a large empire dominating much of western and central Europe during the Middle Ages.
 The Frankish Empire ultimately led to the birth of modern France and Germany and thus the Franks are seen as the forebears of the French and German peoples (in addition to Austrians, the Dutch, Luxembourgers and some other European nations).
The most important phenomenon that took place within the lands of Poland in the Early Middle Ages, as well as other parts of central and eastern Europe, was the arrival and permanent settlement of Slavic peoples.
 The Slavic migrations in the area of contemporary Poland started in the second half of the 5th century AD, about a half century after these territories were vacated by Germanic tribes.
 The first waves of the incoming Slavs settled the vicinity of the upper Vistula River and elsewhere in the lands of present southeastern Poland and southern Masovia.
 Coming from the east, from the upper and middle regions of the Dnieper River, the immigrants would have had come primarily from the western branch of the early Slavs known as Sclaveni, and since their arrival are classified as West Slavs.
 Their early archeological traces belong to the Prague-Korchak culture, which is similar to the earlier Kiev culture.
Chagnoald (Cagnoald, Cagnou) (died 633 AD) was a Frankish bishop of Laon during the 7th century.
 The family to which Chagnoald belonged is known as the Faronids, named after his brother Saint Faro, who was bishop of Meaux, while his sister was Saint Burgundofara, who founded the convent of Faremoûtiers.
 They were the children of the chancellor to Dagobert I, Chagneric.
