King Charles XII of Sweden

King Charles XII of Sweden (1682–1718) was a determined and military-focused ruler who ascended the throne at age 15. Known for his strategic skills, he led Sweden during the Great Northern War (1700–1721), fighting against a coalition of Eastern and Northern European powers. His aggressive campaigns initially expanded Swedish influence but eventually led to significant losses and Sweden's decline as a major European power. He is remembered for his fierce dedication, resilience, and military prowess, dying during a siege in Norway at age 36, leaving a complex legacy as both a military leader and a symbol of Swedish nationalism.
