Cause → Event → Consequence
The Great Northern War, a prolonged conflict between Russia and Sweden for dominance over the Baltic region, had been ongoing since 1700. By 1720, both powers were engaged in naval operations in Baltic waters, with Russia seeking to press its advantage against a weakening Swedish empire.
On 7 August 1720, Russian and Swedish naval forces clashed in the Ledsund strait near the island communities of Föglö and Lemland in Åland. The battle was the final large-scale naval engagement of the Great Northern War, fought in the waters of the Baltic Sea.
The Battle of Grengam brought an end to offensive naval operations by both Russia and Sweden in the Baltic. Russia conducted one further coastal raid on Sweden in spring 1721, after which the Treaty of Nystad was signed, formally concluding the Great Northern War.
