Arson in medieval Scandinavia

Arson in medieval Scandinavia (Old Norse hús-brenna or hús-bruni, "house-burning") was a technique sometimes employed in blood feuds and political conflicts in order to assassinate someone. In committing arson, a group of attackers would set fire to the home of an opponent, sometimes by quickly and surreptitiously piling wood, brush and other combustible materials against the exterior of a dwelling and set it on fire. Typically the attackers would surround the house to prevent the escape of its inhabitants, although women, the elderly, and small children were sometimes allowed to leave.

In Iceland

Under Icelandic law as codified in the Gragas, quickfire could be punished by death only if the arsonists were killed in the act. However, if captured alive the arsonists had to be tried and sentenced to outlawry, even if they were thralls. Failure to observe these formalities could result in the killer of quickfire-arsonists being prosecuted himself. At least some Icelanders considered quickfire dishonorable, hence when the enemies of Gunnar Hámundarson attacked his home they refused to burn him inside, despite the fact that it would have been faster and less costly in lives. Members of Gunnar's clan showed no such scruples when, around 1010, they burned Bergthorshvoll, home of Gunnar's erstwhile ally Njáll Þorgeirsson, his wife Bergþóra, his sons Helgi and Skarphéðinn Njálsson, and his grandson Þórður Kárason. It is because of this occurrence of quickfire that the name of the saga in Icelandic is Brennu-Njáls saga, "The Saga of the Burning of Njáll". One son-in-law, Kári Sölmundarson, escaped and later killed many of the burners. Here is the description of the arson of Njáll's house :
