History of Greenland

The history of Greenland is a history of life under extreme Arctic conditions: currently, an ice sheet covers about eighty percent of the island, restricting human activity largely to the coasts. The first humans are thought to have arrived in Greenland around 2500 BC. Their descendants most likely died out and were replaced and succeeded by several other human groups migrating from continental North America since then. There has been no evidence discovered that Greenland was known to Norsemen until the 9th century AD, when Norse Icelandic explorers settled on its southwestern coast.
