Treasure linked to Viking king 'Harald Bluetooth' found on Baltic island

Hundreds of 1,000-year-old silver coins, rings, pearls and bracelets linked to the era of Danish King Harald Gormsson have been found on the northern German island of Ruegen in the Baltic Sea. Archaeologists said about 100 of the silver coins were probably from the reign of Harald Gormsson, better known as "Harald Bluetooth," who lived in the 10th century and introduced Christianity to Denmark.

'Bluetooth' was one of the last Viking kings of what is now Denmark, northern Germany, southern Sweden and parts of Norway. His nickname came from the fact he had a dead tooth that looked bluish, but it's now best known for the wireless Bluetooth technology invented by Swedish telecom company Ericsson. The company named the technology, developed to wirelessly unite computers with cellular devices, after him for his ability to unite ancient Scandinavia. The technology logo carries the runic letters for his initials HB.
