Harald Bluetooth was king of Denmark in the late 900s. He managed
to unite Denmark and part of Norway into a single kingdom then
introduced Christianity into Denmark. He left a large monument, the
Jelling rune stone, in memory of his parents. He was killed in 986
during a battle with his son, Svend Forkbeard. Choosing this name for
the standard indicates how important companies from the Nordic region
(nations including Denmark, Sweden, Norway and Finland) are to the
communications industry, even if it says little about the way the
technology works.
