Treaty of Frederiksborg

Treaty of Frederiksborg

The Treaty of Frederiksborg was a 1720 peace agreement that ended hostilities between the Kingdom of Denmark–Norway and the Kingdom of Sweden after the Great Northern War. Negotiated in the aftermath of the Treaty of Nystad and the shifting alliances of the War of the Spanish Succession era, the accord restored territorial status and clarified maritime and trade arrangements in the Baltic Sea region. The treaty's provisions influenced later accords such as the Treaty of Stockholm (1720) and affected relations among states like the Electorate of Brandenburg and the Tsardom of Russia.

Background

The treaty arose from the collapse of Swedish power following defeats at the Battle of Poltava and setbacks during the Great Northern War (1700–1721). The Kingdom of Denmark–Norway had previously concluded the Treaty of Roskilde (1658) and faced fluctuating fortunes against Sweden during the Scanian War and the Northern Wars. By 1720, the Riksdag of the Estates in Stockholm and the Danish court at Copenhagen sought stability after interventions by the Holy Roman Empire, the Kingdom of Prussia, and the Margraviate of Brandenburg. Danish ambitions to secure control over the Sound Dues and Swedish efforts to maintain holdings in Skåne and Bohuslän framed the negotiations, alongside concerns involving the Hanoverian dynastic interests and the House of Oldenburg.

Negotiation and Signing

Representatives met at Frederiksborg Castle under mediation influenced by major diplomatic actors such as emissaries from the Kingdom of Great Britain, the Dutch Republic, and envoys associated with the Imperial Court in Vienna. Delegations included ministers aligned with the Kingdom of Denmark–Norway and delegates from the Age of Liberty faction within the Swedish Riksdag. The conference followed precedents set by the Peace of Nystad and the Treaty of Utrecht, and negotiators referenced earlier settlements like the Treaty of Frederiksborg (1700) in diplomatic correspondence. Signing occurred on 3 July 1720, with seals affixed by plenipotentiaries representing the Kingdom of Denmark–Norway under the House of Oldenburg and the Kingdom of Sweden under the regency and parliamentary authorities following the abdication of Charles XII of Sweden influences.

Terms and Provisions

The treaty reaffirmed territorial status quo ante bellum for several contested provinces, aligning with earlier arrangements from the Peace of Nystad and the Treaty of Stockholm (1719–1720). It confirmed the return or retention of territories including parts of Skåne, Halland, and Bohuslän under Swedish administration while recognizing Danish interests in the Duchy of Schleswig and Holstein. Maritime provisions addressed the tolls and rights in the Øresund and the regulation of the Sound Dues that had been central to Copenhagen’s revenue strategy. Commercial clauses referenced trading rights for the Dutch East India Company, the Swedish East India Company, and merchants from Hanover and Lisbon who trafficked along the Baltic Sea and the North Sea. The treaty incorporated indemnities and prisoner exchange protocols mirroring practices from the Treaty of Nystad and financial stipulations reminiscent of arrangements made in the Treaty of Vienna (1725) negotiations. Provisions concerning border demarcation engaged surveying parties from the University of Copenhagen and cartographers linked to the Royal Swedish Academy of Sciences.

Aftermath and Impact

Regionally, the Treaty of Frederiksborg contributed to a reordering of power in Northern Europe that benefited the Tsardom of Russia and the Electorate of Brandenburg-Prussia while constraining Swedish imperial reach. The settlement influenced later diplomatic conferences, including those that produced the Treaty of Stockholm (1720) and subsequent agreements involving the Hanseatic League cities and the Kingdom of Norway. Economically, stabilization of the Øresund toll regime affected merchant houses such as the Dutch East India Company and the British East India Company and altered trade flows between Amsterdam, Hamburg, and Stockholm. Politically, the treaty strengthened the position of factions in the Swedish Riksdag of the Estates that favored reconciliation with neighboring monarchies and provided momentum for internal reforms promoted by figures associated with the Age of Liberty. Military repercussions included demobilization measures comparable to those stipulated in the Peace of Nystad, with reductions in garrison presence across border fortresses like Kronborg and Bohus Fortress.

Ratification and Implementation

Ratification was carried out by the respective legislative bodies: the Danish chancelleries and the Swedish Riksdag approved the articles in separate sessions, invoking precedents from the Treaty of Copenhagen (1660) and citing customs established under the House of Oldenburg. Implementation required joint commissions to delineate borders and oversee prisoner exchanges; these commissions included jurists and engineers educated at the University of Uppsala and the University of Copenhagen. Adjustments to the Sound Dues administration were phased in to accommodate merchants from the Dutch Republic, Kingdom of Great Britain, and Hanover, while indemnity payments were scheduled alongside arms reductions influenced by international observers from the Imperial Court and the Netherlands Republic. Over the following decade, the treaty's terms were enforced through bilateral protocols and local accords mediated by consuls from Hamburg and envoys attached to the courts in Stockholm and Copenhagen.
