part of the empire the six rapidly growing cities of the Teutonic order, Kulm, Thorn, Dantzic, Elbing, Braunsberg, and Koenigsberg; and finally, in Livonia and Esthonia, Riga, Dorpat, Reval, and Pernau.  Noteworthy was the treaty concluded in A.D. 1241, between Hamburg and Lubeck, whereby the former assumed control of the interests in the North Sea and the Elbe, while the latter safeguarded those of the Baltic.  This treaty between Hamburg and Lubeck is sometimes regarded as the beginning of the Hanseatic League.  It has here been sufficiently demonstrated, however, that the association was the result of a slow and gradual process, enforced by conditions, and that it did not originate in the mind of any particular statesman as a definite plan.

The two groups, the maritime and the inland municipal, had developed independently:  it now remained to unite them; and from the union thus effected sprang the great institution of the German Hansa.  The private associations, not excepting the Gothland Company, in view of the rapid extension of commerce and the consequent jealousy of foreign competitors, were no longer able to afford sufficient protection to the foreign trade—­a condition which did not escape the statesmen of Lubeck, with their marked power of initiative and political sagacity.

Thus it came, during the last decades of the thirteenth century, that the private societies became more and more dependent upon the municipal unions, which, under the leadership of the free and centrally located city of Lubeck, now assumed the energetic guardianship of maritime commerce, by reason of which they were drawn from their hitherto isolated position and gradually became fused into an increasingly compact union.

Already at the close of the thirteenth century the young institution of the Hansa received its initiation in warfare in a conflict with the kingdom of Norway, which country was compelled to purchase peace at the price of new and greater concessions to the league.  Soon thereafter, however, the steady progress of the Hansa met with a rebuff.  Denmark, at that time the foremost power of the North, had for more than a century endeavored to obtain the supremacy of the Baltic, at the entrance to which it was so advantageously situated.  At one time Lubeck was for an entire decade forced into a sort of vassalage to the energetic king Eric Menved of Denmark, although the relations to the sister-cities of the league, which had never been entirely severed, were subsequently restored and confirmed by new treaties.  When finally, in A.D. 1361, the Danish king Waldemar Atterdag, inspired by rapacity and revenge, went so far as to fall upon the metropolis of the Baltic, the Swedish city of Wisby, in the midst of peace, and to annex it, thereby inflicting serious losses upon the resident Low-German merchants, Lubeck once more placed herself at the head of the Wendish cities and at the diet of Greifswald decreed war against the ruthless invader.  But the expedition proved disastrous, owing chiefly to the tardiness of the kings of Sweden and Norway, who had been drawn into the alliance.  Nevertheless, the unfortunate admiral of the Lubeck fleet, Johann Wittenborg, who also enjoyed the rank of burgomaster of the Hanseatic city, was put to the axe in the public market-place of Lubeck in expiation of his failure.
