Frederick IV of Denmark

Frederick IV joined the Great Northern War against Sweden, forming an alliance with Russia and Saxony. Denmark's early campaigns failed, leading to the Treaty of Travendal in 1700, which temporarily removed Denmark from the war.

After Sweden's defeat at Poltava, Frederick IV re-entered the Great Northern War. Danish forces invaded Scania but were repelled at the Battle of Helsingborg in 1710, failing to regain lost territories.

Frederick IV signed the Treaty of Frederiksborg ending the Great Northern War for Denmark. Denmark gained the Duchy of Schleswig but failed to recover Scania, and Sweden paid a war indemnity.
