The final settlement at Lund, signed on 16 September (
O.S.) / 26 September 1679, detailed and amended Fontainebleau. French pressure assured that the terms of Fontainebleau were confirmed, as was Sweden's exemption from the
Sound Dues. In addition to these openly proclaimed articles, the treaty included secret paragraphs negotiated by
Johan Göransson Gyllenstierna. They outlined a strategy of mutual assistance, which Gyllenstierna understood was the only way the Scandinavian countries were able to compete with
France and
Brandenburg-Prussia. Gyllenstierna had come to power during the war, and by 1679 controlled Sweden's foreign policy to a point that he was given "free hand" by
Charles XI in negotiating the treaty. His goal was to free the resources bound by the continuous Dano-Swedish hostilities, assert common control of the Baltic Sea, advance to a more favourable commercial position with respect to the
Dutch Republic, and be able to negotiate better terms with
France with respect to military alliances. Yet, as Charles XI and other leading Swedish figures, he was also hostile towards Denmark–Norway, and had proposed to eliminate Denmark–Norway in a joint Franco-Swedish attack just prior to the negotiations. While his motives remain speculative, the secret alliance as laid out in the treaty included several co-operations in northern
Germany, joint negotiations with France, and a joint position regarding the
Baltic Sea trade. A defensive alliance was also concluded, but included in the public part of the treaty. The secret articles of Lund were revealed only in 1870. ==Consequences==
