These negotiations give us an insight into the state of things in Northern waters at that time. At the same time there were difficulties with the Hanseatic League, which tried to seize upon all trade.
Among these so-called Norwegian tributary countries was Greenland, which is mentioned with the others in the complaint of 1431; but whether this means that the English extended their trading voyages, which frequently became piratical expeditions, so far, we do not know; in any case it is not impossible, although of course the voyage to Iceland with its rich fisheries was much more important. We know that this was carried on from Bristol in particular, where, as has been said, many Norwegians were established.
[Sidenote: Possibility of voyages to Greenland in the 15th century (?)]
The statements about Greenland contained in the papal letter of 1448 were, as we have seen, false. Perhaps not very much more weight is to be attached to the story, in Peyrere's "Relation du Groënland" (Paris, 1647), of Oluf Worm of Copenhagen having found in an old Danish MS. a statement that about 1484 there were more than forty experienced men living at Bergen, who were in the habit of sailing to Greenland every year and bringing home valuable goods; but as they would not sell their wares to the Hanse merchants, the latter revenged themselves by inviting them to a supper and killing them all at night. This then was said to be the end of the Greenland voyage, which had to cease thenceforward, because no one knew the course any more [cf. Grönl hist. Mind., iii. pp. 471, f.]. The story as given here is in many respects improbable; but even if the forty or more men and the annual voyage are exaggerations, there are other indications that about that time there may have been some sort of communication with Greenland or the countries to the west of it, as will be mentioned later. The royal monopoly of the Iceland trade was no longer in force, and the same may have applied to Greenland. It is then conceivable that merchants may have gone there; and if their trading prospered they had every reason to keep it as secret as possible, lest others should interfere with their livelihood. This would explain why such voyages are not mentioned by historical authorities. Just then, too, was an uneasy time, with a sort of war of privateers between England and Denmark-Norway, which was not concluded until the provisional peace of 1490; there were thus many pirates and privateers in Northern waters, who may well have extended their activity upon occasion to the remote and unprotected Greenland, where they could plunder with even greater impunity than in Iceland, and perhaps they increased the ruin of the settlements there.
