History of Sweden between 540 AD - 789 AD
In Swedish prehistory, the Vendel era (550-793) is the name given to a part of the Germanic Iron Age (or, more generally, the Migration Period). The migrations and the upheaval in Central Europe had lessened somewhat, and two power regions had appeared in Europe: the Merovingian kingdom and the Slavic princedoms in Eastern Europe and the Balkans. A third power, the Catholic Church, had begun to expand its influence. In Scandinavia, the Germanic clan society was still very much alive. In Uppland in what today is the east-central part of Sweden, Old Uppsala was probably the centre of religious and political life. It had both a well-known sacred grove and great Royal Mounds.
There were lively contacts with Central Europe, and the Scandinavians continued to export iron, fur and slaves; in return they acquired art and innovations, such as the stirrup. The finds in Vendel and Valsgärde show that Uppland was an important and powerful area consistent with the sagas' account of a Swedish kingdom. Some of the riches were probably acquired through the control of mining districts and the production of iron. The rulers had troops of mounted elite warriors with costly armour. Graves of mounted warriors have been found with stirrups and saddle ornaments of birds of prey in gilded bronze with encrusted garnets. These mounted elite warriors are mentioned in the work of the 6th century Goth scholar Jordanes, who wrote that the Swedes had the best horses beside the Thuringians. They also echo much later in the Norse sagas, where king Adils is always described as fighting on horseback (both against Áli and Hrólf Kraki). Snorri Sturluson wrote that Adils had the best horses of his days. Games were popular, as is shown in finds of tafl games, including pawns and dice. This is the time when Swedish expeditions start to explore the waterways of what was to become Russia.
Narikala is an ancient fortress overlooking Tbilisi, the capital of Georgia, and the Kura River. The fortress consists of two walled sections on a steep hill between the sulphur baths and the botanical gardens of Tbilisi. On the lower court there is the recently restored St Nicholas church. Newly built in 1996–1997, it replaces the original 13th-century church that was destroyed in a fire. The new church is of 'prescribed cross' type, having doors on three sides. The internal part of the church is decorated with the frescos showing scenes both from the Bible and history of Georgia.
The fortress was established in the 4th century and it was a Persian citadel. It was considerably expanded by the Umayyads in the 7th century and later, by king David the Builder (1089–1125). Most of extant fortifications date from the 16th and 17th centuries. In 1827, parts of the fortress were damaged by an earthquake and demolished.
