I just saw your bug list for AGCEEP 1.40. If wanted, I'd like to offer my help. For now, here's a description I made of Iceland, Gotland and Normandy:
Iceland:
Although not inhabited until the Viking Age, people knew Iceland long before that time. Iceland was first inhabited round 875 when Norse people started settling there, bringing their pagan gods. By the end of the 10th century the Norwegian king Olaf I Tryggvason forced his subjects to accept Christianity. In the early 13th century the Norwegian king set out to unite all Norwegian Viking Age settlements and in 1264 they were persuaded to swear allegiance to the king of Norway. In the late Middle Ages Iceland's economy, based mostly on farming and fishing, deteriorated and the plague visited Iceland twice killing approximately half the population each time. In 1530 the Reformation was instituted in Denmark but it wasn’t till 1550 that the island’s resistance to the Lutheran Reformation ended. Round 1600 all foreign trade in Iceland was monopolized and given to Danish traders. This arrangement remained intact for nearly two centuries, during which Iceland's contacts with the outside world were almost exclusively restricted to Denmark. The Icelandic people, unlike Norway and Sweden, never demanded more autonomy from Denmark and remained part of Denmark.
Gotland:
Since the 10th century, Gotland had been a part of Sweden, paying an annual tax for protection but otherwise remaining an independent peasant community. Early on Gotland became a commercial center and by the 12th century Gotland dominated the routes between Russia and Western Europe. Until the mid-14th century most of the Novgorod trade passed through the island. They became christianised in the 12th century, brought by a Norwegian king, on the run from his own people. In 1361 the Danish king Valdemar IV Atterdag conquered Gotland after which the trade routes shifted and Gotland declined. For the next three centuries Denmark, Hanseatic League, pirates, and Teutonic Knights variously controlled it, until in 1645 it came again under Swedish rule.
Normandy:
Raids of the Vikings, or Northmen, from the 8th century on, repeatedly devastated the Normandy coast, each time moving farther inland. Finally the French king Charles III the Simple ceded the territory to Rollo, the chief of the largest band of Vikings. The Vikings immigrated in large numbers to settle the country, and they adopted the French language, customs, and religion. These Vikings became known as Normans, and the region they settled became known as Normandy. In 1066, William, duke of Normandy and a distant successor to Rollo, invaded England. He became William I of England (William the Conqueror) and united the rule of England and Normandy in him. During the next four centuries both England and France battled for control over Normandy, until the French achieved permanent control in 1450 after their victory in the Battle of Formigny.
I hope it's satisfactory
