Events

January–June

• March 11 (February 29 Old Style) – Queen Ulrika Eleonora of Sweden resigns, to let her husband Frederick I take over as king of Sweden. She had desired a joint rule, in a similar manner to William III and Mary II in Britain, but as the Swedish Riksdag of the Estates refuses this, she abdicates in her husband's favour instead.

• July 27 – The Battle of Grengam takes place in the Ledsund strait between the island communities of Föglö and Lemland. It was the last major naval battle in the Great Northern War that took place in the Åland Islands, marking the end of Russian and Swedish offensive naval operations in Baltic waters.
• August 14 – The Spanish Villasur expedition, which set out on June 16 from New Mexico, with the intention of checking French influence on the Great Plains of North America, ends in failure, as it is ambushed by a Pawnee and Otoe force.
