Like Vladimir, the Danish king Harald Bluetooth (910–985) was raised as a non-Christian. In the 960s he united Denmark and gained temporary control of Norway. Recognizing the power of Christian monotheism as a unifying force for his new kingdom, he made the decision to convert. (Intel and Ericsson engineers chose to call their new technology “Bluetooth” because it brought computers and mobile phones together just as Harald had unified Denmark and Norway.)
