The fearsome warriors of the Viking Age were predominantly farmers, merchants, and craftsmen who took to raiding to supplement their income. However, as the power of local chieftains and kings grew, these raids became more organized and were conducted on a larger scale farther afield. Elites gradually assumed religious functions in addition to their political ones, which led to an increase in the prevalence of warrior cults, such as those of Odin.
