When one truly looks at Iceland's history objectively, one can see what the real causes of Iceland's collapse was. The lack of competition and the monopolistic qualities that eventually came about when five families cornered the chieftaincy market was one reason. These five families bought the majority of chieftaincies. They controlled the court and legal system to a significant extent. This meant that there were not as many chieftains to choose from. This led to less competition, creating opportunities for increased exploitation over the free farmers, eventually leading to a revolt against the 5 families.
