The history of medieval Iceland and its society drawn by Njal's Saga has been proved by the legend of that age. The history of the Icelandic Commonwealth is based on the history of European settlers who have autonomy with common consent, not kings and pastors. During this period, I revealed the independence of individuals and the political structure that emphasizes the law. As is evidenced by the legend of Iceland like Njal's Saga, there is no political state to enforce the rules and obligations of the structured society.
Saga of Iceland is a prose story based on historical events related to Iceland, which occurred in the 9th century, the 10th century and the early 11th century. This history of Iceland is often called the Saga era. Some of the legends are fantastic, but they are believed to be mainly based on historical truth. Most of what we know about Erik the Red is based on the two Iceland legends, Greenland Saga and Erik the Red's Saga. Erik Thorvaldsson is believed to be born in the Jæren district of Rogaland, located in the southwest end of Norway in 950 AD. His famous name, Erik the Red, probably points to the red color of his hair and beard. It may have been obtained for his temper, which is also considered to be unstable. Eric's father Thorvald Asvaldsson was expelled to Norway by the Norwegians for massacre in about 960.
The legend of Iceland is the history of Ice Island and numerous medieval literary works on families living in the 9th, 10th and 11th centuries. This time was not called the more general "Viking era", it was called "the legendary era" of Iceland. What is unique about the legend of Iceland is that they are considered to be the most authentic look of society in the Viking era. They are in contrast to other sources such as various Christian chronicles, which are written primarily by external observers.
