Hammasaiheiden

Hammasaiheiden, also known as the "Great Northern War," was a significant conflict that took place in the 18th century between Sweden and Russia. The war began in 1700 and lasted until 1721, with a brief interruption from 1714 to 1721. The conflict was part of the larger Great Northern War, which also involved Denmark-Norway, Poland-Lithuania, and Saxony-Poland.

The war was primarily a result of territorial disputes and power struggles in the Baltic region. Sweden, under King Charles XII, sought to expand its influence and territory, while Russia, under Peter the Great, aimed to secure its borders and challenge Swedish dominance. The war was marked by several major battles, including the Battle of Poltava in 1709, which is considered one of the largest and bloodiest battles in European history.

The Treaty of Nystad, signed in 1721, officially ended the war. Sweden was forced to cede significant territories to Russia, including the provinces of Ingria and Karelia. The war had profound implications for both Sweden and Russia, shaping their future political and military strategies. It also marked the beginning of Russia's rise as a major European power.
