Background and detail

Military Context. Following the occupation of Jutland by Tilly and Wallenstein in 1627, Christian IV launched an amphibious campaign in 1628 to destroy naval facilities in Ålborg, Wismar, and Greifswald. These successes, combined with the threat of a Danish-Swedish alliance, strengthened Christian's negotiating position against Wallenstein, who feared losing access to the Baltic.

Negotiations. Despite pressure from the Catholic League to continue the war, emissaries from both sides met in Lübeck in January 1629. Christian IV's position was bolstered by his 1628 military successes and his personal meeting with Gustavus Adolphus of Sweden in February 1629, which heightened Wallenstein's fear of a Scandinavian alliance.

Treaty Terms. The treaty was concluded on 22 May 1629 and ratified by Ferdinand II on 7 June. It ended the Danish intervention without territorial diminution for Denmark, but bound Christian IV not to interfere further in the Thirty Years' War. This removal of Danish obstacles facilitated Gustavus Adolphus's entry into the war in 1630.
