Sweden and Prussia sign the Treaty of Stockholm.

The Treaty of Stockholm, signed in 1720, marked a pivotal moment in European history, concluding hostilities between Sweden and Prussia during the final stages of the Great Northern War (1700–1721). Under the treaty’s terms, Sweden ceded Swedish Pomerania south of the Peene River, including the island of Usedom, to Prussia, significantly altering the balance of power in the Baltic region. In exchange, Prussia compensated Sweden with a monetary sum, ensuring its territorial gains while avoiding further military entanglements. This treaty was part of a broader effort to resolve the war, as Sweden sought to stabilize its diminished empire following repeated defeats, while Prussia emerged as a rising power. The agreement not only reinforced Prussia’s ambitions but also reflected the shifting dynamics of European politics in the early 18th century.
