Map of the eastern Norse settlement in medieval Greenland. The area is within the current municipality of Kujalleq. The known major farms and churches are identified, as well as some probable geographical names.
The Eastern Settlement (Old Norse: Eystribyggð) was the first and largest of the three areas of Norse Greenland, settled c. AD 985 by Norsemen from Iceland. At its peak, it contained approximately 4,000 inhabitants. The last written record from the Eastern Settlement is of a wedding solemnized in 1408, placing it about 50–100 years later than the end of the more northern Western Settlement.
Despite its name, the Eastern Settlement was more south than east of its companion and, like the Western Settlement, was located on the southwestern tip of Greenland at the head of long fjords: Tunulliarfik Fjord or Eiriksfjord, Igaliku or Einarsfjord, Sermilik Fjord, to name a few (see map at right).
The economy of the medieval Norse settlements was based on livestock farming - mainly sheep and cattle, with significant supplement from seal hunting. A climate deterioration in the 14th century may have increased the demand for winter fodder and at the same time decreased productivity of hay meadows. Isotope analysis of bones excavated at archaeological investigations in the Norse settlements have found that fishing played an increasing economic role towards the end of the settlement's life. While the diet of the first settlers consisted of 80% agricultural products and 20% marine food, from the 14th century the Greenland Norsemen had 50–80% of their diet from the sea.
In the Greenlandic Inuit tradition, there is a legend about Hvalsey. According to this legend, there was open war between the Norse chief Ungortoq and the Inuit leader K'aissape. The Inuit made a massive attack on Hvalsey and burned down the Norse inside their houses, but Ungortoq escaped with his family. K'aissape conquered him after a long pursuit, which ended near Kap Farvel. However, according to archaeological studies, there is no sign of a conflagration.
