1667

1667 was a year marked by significant diplomatic settlements that reshaped colonial and regional power balances in Europe and its overseas empires.

In the Atlantic world, the Second Anglo-Dutch War concluded with the Treaty of Breda. The agreement ended hostilities between England and the Dutch Republic and established colonial settlements that influenced head-to-head imperial rivalry for years to come. Notably, the Dutch gained Suriname in South America, while England secured the Caribbean island of Tobago, helping to define the respective colonial empires of both states.

In Eastern Europe, the Russo-Polish War (1654–1667) ended with the Treaty of Andrusovo. The settlement redrew borders along the Dnieper River and shifted influence between the Polish-Lithuanian Commonwealth and the Tsardom of Russia, with Russia gaining control over Ukrainian lands on the left bank and a greater say in regional affairs. The agreement altered the balance of power in the region and set the stage for subsequent alternations of control in Ukrainian and neighboring territories.

Beyond these two major diplomatic milestones, 1667 saw ongoing imperial competition and conflict across various theaters, as European powers negotiated borders, trade, and influence. The year's treaties helped shape late 17th-century geopolitics by clarifying possessions and spheres of influence that would influence regional and global dynamics for years to come.
