ded south and arrived in Labrador and Newfoundland. Upon the brothers' return to Portugal, the cartographic information supplied by Corte-Real was incorporated into a new map of the world which was presented to the Ercole I d'Este, Duke of Ferrara by Alberto Cantino in 1502. The Cantino planisphere, made in Lisbon, accurately depicts the southern coastline of Greenland.
King Christian IV's Expeditions to Greenland was a series of expeditions in the years 1605–1607 to Greenland and Arctic waterways in order to locate the lost eastern Norse settlement and assert Danish sovereignty over Greenland. The expeditions were mostly unsuccessful, partly due to leaders who lacked experience with the difficult arctic ice and weather conditions, and partly because the expedition leaders were given instructions to search for the Eastern Settlement on the east coast of Greenland just north of Cape Farewell, which is almost inaccessible due to southward drifting ice. The pilot on all three trips was English explorer James Hall.
After the Norse settlements died off, the area came under the de facto control of various Inuit groups, but the Danish government never forgot or relinquished the claims to Greenland that it had inherited from the Norwegians; and when contact with Greenland was re-established in the early 18th century, Denmark asserted its sovereignty over the island. In 1721, a joint mercantile and clerical expedition led by Danish-Norwegian missionary Hans Egede was sent to Greenland, not knowing whether a Norse civilization remained there. The expedition can be seen as part of the Danish colonization of the Americas. After 15 years in Greenland, Hans Egede left his son Paul Egede in charge of the mission in Greenland and returned to Denmark where he established a Greenland Seminary. This new colony was centered at Godthåb ("Good Hope") on the southwest coast. Gradually, Greenland was opened up to Danish merchants, and closed to those from other countries
