On March 2, 1534, the Congress was opened by the Burgomaster of Hamburg in the grand council chamber of the local guildhall, an historical room, unfortunately destroyed in the great fire that devastated Hamburg in 1842. In an eloquent speech the local magnate described the miseries entailed by the war in which the Lübeckers had engaged against the Dutch, and urged that peace should be concluded in the interest of the common Hanseatic merchants. The burgomaster was followed by an imperial councillor, who said the same things in yet stronger terms. Wullenweber was visibly angered. His anger was increased when the Dutch envoy rose to his feet and claimed that it should be laid down as a principle "that the sea and all other waters should be free to the shipping of whosoever listed," adding that "if the Lübeckers suffered damage in consequence, they should find comfort in God's will and in the mutability of all earthly things."
This was too much for Wullenweber's temper to bear. He declared with violence that if the speeches continued in this tone and spirit he and his colleagues should leave the assembly, and this, in fact, they shortly afterwards did. Not only did he leave the assembly, but the city also, after he found that all the demands of Lübeck fell on deaf ears. But before he left he made a powerful speech in the guildhall, wherein he asserted and maintained that all he had done had been done solely for the general benefit of the League. He even accused the other Hanseatic delegates of being Dutch in sympathy, "a thing," he added, "which they and the Dutch would repent of as long as he lived."
He was asked to explain his projects. He sketched a plan almost identical in spirit with the Navigation Act of Cromwell; it might indeed almost be regarded as its prototype. When taunted regarding the egotism of this proposal, when told that the sole purpose that inspired it was to prevent the vessels of other powers from deriving a profit out of carriage of goods, Wullenweber retorted as angrily as Cromwell might have done, and with the same contempt for the petty spirits that could see no higher object, nor any larger or wider aims than purely personal and financial ones. To Wullenweber's mind there was at stake not only vulgar profit, but the control and supervision of the Baltic trade, the maintenance of the Hanseatic colonies, indeed of all commercial navigation; in a word, of everything that had made the Hansa what it was.
The colonial policy pursued by the Hansa, which had been one of its sources of strength, became a cause of weakness, and ultimately led to its fall. It was based in all essentials upon the same principles as those pursued later by other nations with regard to their foreign non-European colonies, and which led in time to the loss of these same colonies. The chief points were these: that the direct intercourse and traffic with the Eastern settlements and their commercial domain were reserved exclusively to Hanseatic vessels, and that transport by land was forbidden, because in that case it was not so easy to keep watch upon business, and to be assured that no Hanseatic laws were transgressed. Foreign flags were excluded from all Eastern ports and non-Hanseatic merchants not admitted to their markets. All traffic from the Eastern cities to non-Hanseatic places, and all traffic with these places were to go by way of Lübeck. This is the sum of the Lübeck Staple Act, which had a little sunk into abeyance during the late disorders and which Wullenweber desired to see fully reinforced. Again, to refer to England's dictator, with whom Wullenweber had some points of resemblance, this Lübeck staple was neither more nor less than the British staple, prescribed by Cromwell's Navigation Act, when it excluded foreign flags from American harbours, and interdicted the Americans from sending ships to any other European harbour than those of the mother-land. Two hundred years separated these two Tribunes of the People from each other, and yet, in some respects, their ideals and ideas were identical. But to return to the course of our narrative, which has been interrupted in order to make clearer the aims the Lübeck burgomaster had in view.
Wullenweber grew daily more angered at the tone adopted in the Congress, not only from his opponents, but by those from whom he had a right to look for support.
On March 12th, accompanied by Max Meyer, and the same military train with which he had entered, he left Hamburg, shaking the dust of the city off his feet in anger. He was soon followed by the delegates of the other Baltic cities. The congress had come to an untimely end, and nothing had been settled.
Wullenweber's object in returning so precipitately was twofold. He desired to know the wishes of the city under the changed circumstances, and he wished to complain of the colleagues who had failed to support him. This precipitous return greatly alarmed the citizens, all the more because during Wullenweber's absence the aristocratic party had tried to lodge various complaints against the absent burgomaster, and to stir up the people to revolt and discontent. They had even ventured to insinuate that he was guilty of "stealing and treason." Indeed, the tumult in the city was so great and seemed so threatening, that many timid spirits began to think that discretion was the better part of valour, and that it would be well to absent themselves awhile.
Into this state of affairs Wullenweber, by his unexpected return, dropped like a bombshell. He saw that energetic steps were needful here. He did not hesitate for a moment to take them. A meeting of the Forty-six was held, who were charged to invite the burghers to a general assembly in St. Mary's Church. More than a thousand persons replied to the summons. Wullenweber mounted the pulpit. In ardent words he expressed his patriotic intentions, and related in detail the reasons for his abrupt departure from Hamburg. He also complained most bitterly of the conduct of those who should have supported him. Next day he addressed a similar meeting in the guildhall, and spoke, if possible, in stronger terms, openly accusing his opponents of envy, and saying he was well aware that some among them even intended to attack him at night in his house, and to make him prisoner.
The upshot of his two speeches was that the democratic party once more gained the upper hand; that it was agreed that Wullenweber should act entirely according to his own discretion in the matter with the Netherlanders; that three of the municipal councillors inimical to him should be removed from their place; and that various burghers, whom he designated as "of Swedish or Netherlandish sympathy," should either be banished or imprisoned.
With his power thus increased, Wullenweber returned to Hamburg, and the congress was reopened. Since, however, he could gain no support from the other Hanseatic cities for his policy of continuing the war with the Netherlands, he at last consented to accept a truce of four years; a truce which he recognized would leave his hands free for the execution of his other plans.
