The Treaty of Åbo was the culmination of the Russo-Swedish War, which lasted from 1741 to 1743. This conflict erupted as Sweden sought to reassert itself in the region and reclaim territories lost during earlier wars, while Russia, under Empress Elizabeth, aimed to expand its influence and secure its borders. The war saw several battles, with both sides experiencing victories and losses. However, lack of resources and internal political issues led to Swedish fatigue and a desire for peace. The negotiations took place in Åbo, modern-day Turku, Finland, where envoys from both countries convened to finalize the treaty. The terms of the treaty were favorable to Russia, which secured several key territories along the eastern coast of the Gulf of Bothnia and parts of Finland, shifting the balance of power in the region significantly. This treaty laid the groundwork for future Russian expansionism and diminished Swedish influence in Northern Europe. The peace also highlighted the changing dynamics of power in Europe, as the traditional military might of Sweden was challenged by the rising strength of Russia.
