Troll, troll is usually used as a term for a kind of supernatural Old Scandinavian nature, but can also be a term for a person with special properties.
During the persecution of people accused of magical operations in Scandinavia in the 1500 - and 1600's was the crime they allegedly committed, described as magic. The correct legal term for criminal respectively witch and wizard - the majority referred to as witches. The modern German umbrella term witch was first introduced in Denmark-Norway, Iceland and Sweden at the end of the 1600s, and is therefore not used in the legislation against witchcraft activities either in Norway or other Nordic countries.
The concept of witchcraft is derived from the term troll that has a long, ambivalent and partially written story in Scandinavia (Read about this in Catharina Raudveres article "Trolldómr in Early Medieval Scandinavia"). Typically, troll identified as a type figure with characteristics that giant, evil, sinister and ugly - almost as a kind of monster or monster. But in other cases, troll be perceived as dwarf-like creatures, it is not unusual to talk about kid stuff. The similarities is that all trolls are anti-social, they act in the dead of night, and they have no particular gender identity. Different combinations of words which control is included as the first or second paragraph is very widespread and numerous. In Norse sagas have ideas about trolls generally a derogatory and negative undertone. "You're more like a troll than a man," was perceived as a highly defamatory utsagt. Troll occur in myths, fairy tales, legends, folklore and ban. Their habitat is often associated with the underworld and Hades and often added to the Scandinavian mountains and deep forests.
The concept of witchcraft, which is the derivative of the term troll, evolved as a result of a historic transformation process where trolls go from deceased relatives to be demons. From about the 1500s describes the crime witchcraft as a contact between humans and demons, or, in other words, between witches and wizards. This gradual historical change means a demonization of the notion of control. Troll denotes no longer a connection to the deceased, but for Satan and his demons. In 1587 wrote the Danish minister Hans Lauridsen in Sielebog (1587, page 90) that the troll was nothing other than the fallen demons. From this time, most of the supernatural beings demonized. This process can be seen as a kind diabolisering of Nordic folklore.
From the 1700s to the present day
During the 1700s harmless trolls done gradually before up to our own time have a renaissance as part of the growing market for entertainment magic. The Nordic trolls got a romantic veil over it and became more and more stupid spectacular fantasy figures, often depicted as multiheaded beings. The strict laws about the persecution of trollpeople, however, abolished around 1840. Besides the application as scary characters in fairy tales for children, witch in our modern world has become an important Scandinavian tourist product and acting otherwise as the monster figures in popular horror films from the far north.
Silly christianity skewed everything around trolls and no one knows what a true Norwegian troll is.
