1430 - 1500 (Midnight Sun)

This is the timeline for the [Midnight Sun TL.

PoD

 * 1430. The Greenland Norse are pushed to the edge of starvation by worsening climactic conditions and hostile Inuit, abandoning their Western Settlement to withdraw to the very southern tip of Norway. After the daughter of a major chief, Jon Arnason, starves to death, he realizes that the colony will be destroyed unless serious action is taken. He orders his men to begin large-scale fishing in an attempt to utilize a new food source.
 * 1431. After Arnason survives the winter in a far greater state of comfort than his non-fishing compatriots, they also adopt it. As there is a shortage of boats to fish from, or timber to build new boats, the Norse for the first time offer to trade iron for Inuit kayaks. The Inuit accept, and a trading post is set up at the former Western Settlement.
 * 1432. Arnason's son Einar is stranded at the Western Settlement over the winter, but is fortunately taken in by the Inuit. He acquires a working knowledge of their language, and marries an Inuit woman. Meanwhile, the Eastern Settlement begins hunting whales in line with Inuit custom, enabling them to gain a supply both of food and fuel.
 * 1433. Several Norse overwinter at the Western Settlement, where Einar Arnason's first child, a daughter named Freydis, is born. The Inuit are able to make a much larger and more successful hunt using iron tools, and request, through Einar, that a blacksmith be sent to the Western Settlement.
 * 1434. The Western Settlement has expanded into a joint Inuit-Norse community of around 60 people. The Inuit begin to adopt iron tools on a larger scale, and produce larger kayaks carrying two to three passengers. After the death of the Inuit chief at the Western Settlement, or Ivituut, Einar Arnason is made the new chief by acclamation. The last cows die out in southern Greenland after fodder proves inadequate. Only sheep, goats and dogs are left to the Norse.
 * 1435. The main hay barn burns down at the Eastern Settlement, starving about 90% of the livestock. The people begin to starve also, and attack the richer farms, killing much of their breeding stock. Jon Arnason is one of the dead. Some hundreds trek over southern Greenland to Ivituut, but most die on the way.
 * 1436. An expedition from the Western Settlement reaches the Eastern one, finding only a few thousand people still alive. Most are evacuated to the Western settlement, leaving only around a thousand. After they request more hunters, several dozen Inuit move south to the Eastern settlement, greatly enhancing its food production capabilities.
 * 1437. The last priest consecrated by the last bishop sent from Europe dies. Several dozen Norse object to the fact that no baptism, absolution, or other religious ceremony can now be carried out. Some leave in two of the last remaining ships for Europe. They are never heard from again, and were presumably killed by the impassable conditions in the North Sea.
 * 1438. After a glacier cuts off the fjord at the Western Settlement, Einar Arnason orders the community, now numbering around 500, transferred wholesale to the Eastern Settlement. The Inuit inhabitants also move.
 * 1439. Several hundred Inuit arrive at the Eastern - and now only- Settlement this year to trade. Some stay there, and take up sheep farming or act as hunters for the less competent Norse. Some of the poorer Norse return north to the Inuit, judging it better to be well-fed barbarians than starving civilized people.
