They were free men and enjoyed rights such as the use of weapons and the privilege to join the Thing as farm owners landlords. The profile is specified in Rígsthula, a Scandinavian legend describing the god Ríg lying with three couples to procreate and give birth to the three social classes: thralls, karls and earls. The poem describes the image and behavior as it should be, and the type of work expected at each.

The odalsbóndi could give up some of their land to other karls in exchange for loyalty and unconditional support whenever necessary. However, the term karl in some ancient writings denoting a free man status of low social class without access to family ties with upper castes or royalty.
