Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
SvetovitSvetovit, Sventovit, Svantovit is the god of abundance and war, and the chief god of the Slavic tribe of the Rani, and later of all the Polabian Slavs. His organized cult was located on the island of Rügen, at Cape Arkona, where his main temple was also located. According to the descriptions of medieval chroniclers, the statue representing this god had four heads, a horn and a sword, and to the deity himself were dedicated a white horse, a saddle, a bit, a flag, and eagles.
GaelsThe Gaels (ɡeɪlz ; Na Gaeil n̪ɣə ˈɡeːlj; Na Gàidheil nə ˈkɛː.al; Ny Gaeil nə ˈɡeːl) are an ethnolinguistic group native to Ireland, Scotland and the Isle of Man. They are associated with the Gaelic languages: a branch of the Celtic languages comprising Irish, Manx and Scottish Gaelic. Gaelic language and culture originated in Ireland, extending to Dál Riata in western Scotland. In antiquity, the Gaels traded with the Roman Empire and also raided Roman Britain.
Slavic paganismSlavic mythology or Slavic paganism is the religious beliefs, myths, and ritual practices of the Slavs before Christianisation, which occurred at various stages between the 8th and the 13th century. The South Slavs, who likely settled in the Balkan Peninsula during the 6th–7th centuries AD, bordering with the Byzantine Empire to the south, came under the sphere of influence of Eastern Christianity, beginning with the creation of writing systems for Slavic languages (first Glagolitic, and then Cyrillic script) in 855 by the brothers Saints Cyril and Methodius and the adoption of Christianity in Bulgaria in 864 and 863 in Great Moravia.
Christian missionA Christian mission is an organized effort for the propagation of the Christian faith. Missions involve sending individuals and groups across boundaries, most commonly geographical boundaries, to carry on evangelism or other activities, such as educational or hospital work. Sometimes individuals are sent and are called missionaries, and historically may have been based in mission stations. When groups are sent, they are often called mission teams and they do mission trips.
TheodoretTheodoret of Cyrus or Cyrrhus (Θεοδώρητος Κύρρου; AD 393 – 458/466) was an influential theologian of the School of Antioch, biblical commentator, and Christian bishop of Cyrrhus (423–457). He played a pivotal role in several 5th-century Byzantine Church controversies that led to various ecumenical acts and schisms. He wrote against Cyril of Alexandria's 12 Anathemas which were sent to Nestorius and did not personally condemn Nestorius until the Council of Chalcedon.
Northern CrusadesThe Northern Crusades or Baltic Crusades were Christian colonization and Christianization campaigns undertaken by Catholic Christian military orders and kingdoms, primarily against the pagan Baltic, Finnic and West Slavic peoples around the southern and eastern shores of the Baltic Sea, and also against Orthodox Christian Slavs (East Slavs). The most notable campaigns were the Livonian and Prussian crusades. Some of these wars were called crusades during the Middle Ages, but others, including most of the Swedish ones, were first dubbed crusades by 19th-century romantic nationalist historians.
SaxonsThe Saxons (Saxones, Sachsen, Seaxan, Sahson, Sassen, Saksen) were a group of Germanic peoples whose name was given in the early Middle Ages to a large country (Old Saxony, Saxonia) near the North Sea coast of northern Germania, in what is now Germany. In the late Roman Empire, the name was used to refer to Germanic coastal raiders, and in a similar sense to the later "Viking" (pirate or raider). Their origins are believed to be in or near the German North Sea coast where they appear later, in Carolingian times.
Christianisation of the Germanic peoplesThe Germanic peoples underwent gradual Christianization in the course of late antiquity and the Early Middle Ages. By AD 700, England and Francia were officially Christian, and by 1100 Germanic paganism had also ceased to have political influence in Scandinavia. Germanic peoples began entering the Roman Empire in large numbers at the same time that Christianity was spreading there. The connection of Christianity to the Roman Empire was both a factor in encouraging conversion as well as, at times, a motive for persecuting Christians.
DonatismDonatism was a Christian sect leading to a schism in the Church, in the region of the Church of Carthage, from the fourth to the sixth centuries. Donatists argued that Christian clergy must be faultless for their ministry to be effective and their prayers and sacraments to be valid. Donatism had its roots in the long-established Christian community of the Roman province Africa Proconsularis (present-day Tunisia, the northeast of Algeria, and the western coast of Libya) and Mauretania Tingitana (roughly with the northern part of present-day Morocco), in the persecutions of Christians under Diocletian.
