However, the number of independent farmers probably decreased with time as they were forced into becoming tenants of the chiefs, a process that is well documented in Iceland. We don’t have corresponding records for the process in Greenland, but it seems likely there too, because the forces promoting it were even more marked in Greenland than in Iceland. Those forces consisted of climate fluctuations driving poorer farmers in bad years into debt to richer farmers who lent them hay and livestock, and who could eventually foreclose on them.
