So far, however, the Union only exercised rights abroad. It was from Wisby also that the reaction was to come for union at home; but this was a little later, when its strength was well matured and established.
What really, in the first instance, led the Germans from their inland towns to the shores of the Baltic was the desire to benefit by the great wealth that lay hidden in its waters in the form of fish, which could be obtained in return for the mere labour of fishing. At a time when all Europe was Catholic, or of the Greek Church, and fasts as well as feasts strictly observed, the sale of fish was an important industry, and, above all, of salted fish, since our forefathers were ignorant of the art of preserving these creatures fresh by means of ice. Now, from the beginning of the twelfth century until the beginning of the fifteenth, when they once more altered their course, each spring and autumn the migratory fish, and especially that most prolific and valued of fish, the herring, came in great shoals to the shores of Scania,[4] the isle of Rügen, and the coasts of Pomerania, tempting the inhabitants of the strand and near inland hamlets out on to the waters to secure these treasures. Nor had nature herewith ceased her bounties. At certain points of the littoral there were salt springs, in which the precious draught could at once be pickled; and it is certain that the art of preserving the gifts of the ocean from decay was familiar to the Slav inhabitants of these districts long before it was known to those of the German Ocean. Already, in the eleventh century, "salt Kolberg" was famed as an emporium for salted herrings; and the words of a Polish poem of rejoicing at a victory won over its inhabitants in 1105 are extant to this day. It has more historical than literary value. "Formerly," so jubilantly sang the conquerors of the harbour, "they brought us salt and stinking fish, now our sons bring them to us fresh and quivering."
Salted herrings became an acknowledged form of tax or tribute, as also a medium of exchange for inland produce, and it was the value of these small fish that really first roused the cupidity of the inland dweller and caused them to compete with and finally oust the pagan Slav. And Wisby for a time was their great emporium, whence they extended their power, founding among other towns Novgorod on the Lake of Olm. It was to Wisby that association dues were paid; it was in Wisby that common money was deposited. They were kept in the German Church of Our Lady Maria Teutonicorum. For the churches in those times were buildings as much secular as religious, being not only places of worship, but also banks, storehouses, market-places, and sanctuaries. Four aldermen, selected from important cities of the League, namely, Wisby, Lübeck, Soest, and Dortmund, had each a key to the common treasure. The rules laid down in common council, over which these aldermen presided, and whose execution they enforced, were stringent in the extreme. For example, according to an old principle of Teutonic laws, a city was made responsible if a trader suffered malignant shipwreck or was robbed of his goods within its domain, and if these things occurred they were bound to help the sufferers to recover their goods or safety.
That it was not always an easy task for the towns to execute this command may be gathered from the fact that in the earliest times even the Church looked on flotsam and jetsam as its legitimate dues; indeed, the revenues of some monasteries and churches were distinctly founded on this. Even Papal authority, even excommunication in later days, could not for a long while break the force of a barbarous and cruel custom. All the booty the waves cast on the shore was designated by the well-sounding term of strandgut (property of the shore), and was regarded as a gift from Providence. The dwellers on the Baltic shore held so naïve a belief with respect to this matter that in their daily prayers they innocently asked God to give them a good harvest of strandgut.
Lübeck in 1287, demanding from Reval, on the basis of its treaties, the restitution of stranded property, is told frankly by the governor of the city that "however many and long and large letters they may send him across the seas," yet his vassals would hold to the rights of their land, and "if," he adds, "on your letters or your prayers your goods are restored to you, I will suffer my right eye to be put out."
Still by steady persistence the German cities got their will, and of course they exercised it first on members of their union. The defaulting city had to pay a fine of something like two to three hundred pounds of our money to the common fund of the Union, and, in event of a recurrence, was threatened with expulsion from the community. This punishment was called unhansing, and it was inflicted several times, and was only atoned for by the heaviest penalties not only of money tributes, but often of pilgrimages to some distant sacred shrine, to wipe out the disgrace that the city had drawn down, not on itself alone, but also on its brethren of the League, by the fact that there could be such a black sheep among them.
Such, briefly, was the empire that, by the middle of the thirteenth century, was exercised by a community of German men of commerce, who had their seat of control, not at home, but on a foreign soil. Such, briefly, was the rise of these powerful merchants who not only dared to dictate terms to distant cities, but were absolutely obeyed. Such, briefly, was the transformation of bands of pirates and adventurous traders into a peace-loving and industrious association.
Let us now take a rapid glance at what had occurred meantime in the Holy Roman Empire and the towns.
