Grœnlendinga saga (Old Norse pronunciation: [ˈgrøːnˌlendingɑ ˈsɑɣɑ]; Modern Icelandic: Grænlendinga saga, Icelandic pronunciation: [ˈkrainˌlɛntinka ˈsaːɣa] , literally Saga of the Greenlanders), is one of the sagas of Icelanders. Like the Saga of Erik the Red, it is one of the two main sources on the Norse colonization of North America. The saga recounts events that purportedly happened around 1000 and is preserved only in the late 14th century Flateyjarbók manuscript.
The Saga of the Greenlanders starts with Erik the Red, who leaves Norway and colonizes Greenland. It then relates six expeditions to North America, led respectively by Bjarni Herjolfsson, Leif Erikson, Thorvald Eriksson, Thorstein Eriksson and his wife Gudrid Thorbjarnardóttir, Thorfinn Karlsefni, and Freydís Eiríksdóttir. Bjarni and his crew discover three lands by chance during their voyage to Greenland, but they never set foot on the lands themselves. Leif learns about Bjarni's encounters and, after buying Bjarni's ship, sails to the lands to explore them. During his adventures, Leif names the three lands Helluland, Markland, and Vinland. Later, Thorvald, Leif's brother, sets sail to Vinland and lives there until he gets killed by the natives in a combat. Thorstein and Gudrid attempt to travel to Vinland but eventually fail, and thereafter Thorstein dies of an illness. Karlsefni, who then marries Gudrid, journeys to Vinland and stays there until the following spring. The final expedition is made by Freydís, who sails to Vinland with the brothers Helgi and Finnbogi but eventually slaughters their crew and returns to Greenland.
