History of Germany between 487 AD - 843 AD
Numerous small Frankish kingdoms existed during the 5th century around Cologne, Tournai, Le Mans, Cambrai and elsewhere. After the fall of the Western Roman Empire, the Franks created an empire under the Merovingian kings and subjugated the other Germanic tribes. The Merovingian kings of the Germanic Franks conquered northern Gaul in 486 AD. Swabia became a duchy under the Frankish Empire in 496, following the Battle of Tolbiac; in 530 Saxons and Franks destroyed the Kingdom of Thuringia. In the 5th and 6th centuries the Merovingian kings conquered several other Germanic tribes and kingdoms. King Chlothar I (558–561) ruled the greater part of what is now Germany and made expeditions into Saxony, while the Southeast of modern Germany was still under influence of the Ostrogoths. Saxons inhabited the area down to the Unstrut River.
Regions of the Frankish Empire were placed under the control of autonomous dukes of mixed Frankish and native blood. Frankish Colonists were encouraged to move to the newly conquered territories. While the local Germanic tribes were allowed to preserve their laws, they were pressured into becoming Christians.
The German territories became part of Austrasia (meaning "eastern land"), the northeastern portion of the Kingdom of the Merovingian Franks. As a whole, Austrasia comprised parts of present-day France, Germany, Belgium, Luxembourg and the Netherlands. After the death of the Frankish king Clovis I in 511, his four sons partitioned his kingdom including Austrasia. Authority over Austrasia passed back and forth from autonomy to kingly subjugation, as Frankish lands were alternately united and subdivided by the Merovingian kings.
In 718, Charles Martel, the Franconian Mayor of the Palace, made war against Saxony because of its help for the Neustrians. His son Carloman started a new war against Saxony in 743, because the Saxons gave aid to Duke Odilo of Bavaria.
In 751, Pippin III, Mayor of the Palace under the Merovingian king, himself assumed the title of king and was anointed by the Church. Now the Frankish kings were set up as protectors of the pope, and Charles the Great launched a decades-long military campaign against their heathen rivals, the Saxons and the Avars. The campaigns and insurrections of the Saxon Wars lasted from 772 to 804. The Saxons and Avars were eventually overwhelmed, the people were forcibly converted to Christianity, and the lands were annexed by the Carolingian Empire.
After the death of Frankish king Pepin the Short in 768 AD, his son Charles consolidated his control over his kingdom and became known as "Charles the Great" or "Charlemagne." From 771 until his death in 814, Charlemagne extended the Carolingian empire into northern Italy and the territories of all west Germanic peoples, including the Saxons and the Baiuvarii (Bavarians). In 800, Charlemagne's authority was confirmed by his coronation as Holy Roman Emperor by the pope on Christmas Day in Rome. Imperial strongholds (Kaiserpfalzen) became economic and cultural centres, of which Aachen was the most famous.
Fighting among Charlemagne's grandchildren caused the Carolingian empire to be partitioned into several parts by the Treaty of Verdun (843), the Treaty of Meerssen (870), and the Treaty of Ribemont. The German region developed out of the East Frankish kingdom, East Francia.
The Church of Saint Demetrius, or Hagios Demetrios, is the main sanctuary dedicated to Saint Demetrius, the patron saint of Thessaloniki. It is part of the site Palaeochristian and Byzantine Monuments of Thessaloniki on the list of World Heritage Sites by UNESCO since 1988.
The first church on the spot was constructed in the early 4th century AD, replacing a Roman bath. A century later, a prefect named Leontios replaced the small oratory with a larger, three-aisled basilica. Repeatedly gutted by fires, the church eventually was reconstructed as a five-aisled basilica in 629–634. This was the surviving form of the church much as it is today. The most important shrine in the city, it was probably larger than the local cathedral. The historic location of the latter is now unknown.
The church had an unusual shrine called the ciborium, a hexagonal, roofed structure at one side of the nave. It was made of or covered with silver. The structure had doors and inside was a couch or bed. Unusually, it did not hold any physical relics of the saint. The ciborium seems to have been a symbolic tomb. It was rebuilt at least once.
The basilica is famous for six extant mosaic panels, dated to the period between the latest reconstruction and the inauguration of the Byzantine Iconoclasm in 730. These mosaics depict St. Demetrius with officials responsible for the restoration of the church (called the founders, ktetors) and with children. An inscription below one of the images glorifies heaven for saving the people of Thessalonica from a pagan Slavic raid in 615.
Thessaloniki became part of the Ottoman Empire in 1430. About 60 years later, during the reign of Bayezid II, the church was converted into a mosque, known as the Kasımiye Camii after the local Ottoman mayor, Cezeri Kasım Pasha. The symbolic tomb however was kept open for Christian veneration. Other magnificent mosaics, recorded as covering the church interior, were lost either during the four centuries when it functioned as a mosque (1493–1912) or in the Great Thessaloniki Fire of 1917 that destroyed much of the city. It also destroyed the roof and upper walls of the church. Black-and-white photographs and good watercolour versions give an idea of the early Byzantine craftsmanship lost during the fire.
Following the Great Fire of 1917, it took decades to restore the church. Tombstones from the city"s Jewish cemetery - destroyed by the Greek and Nazi German authorities - were used as building materials in these restoration efforts in the 1940s. Archeological excavations conducted in the 1930s and 1940s revealed interesting artifacts that may be seen in a museum situated inside the church"s crypt. The excavations also uncovered the ruins of a Roman bath, where St. Demetrius was said to have been held prisoner and executed. A Roman well was also discovered. Scholars believe this is where soldiers dropped the body of St. Demetrius after his execution. After restoration, the church was reconsecrated in 1949.
