Charles XII, sometimes Carl XII or Carolus Rex, was King of Sweden from 1697 to 1718. He belonged to the House of Palatinate-Zweibrücken, a branch line of the House of Wittelsbach. Charles was the only surviving son of Charles XI and Ulrika Eleonora the Elder. He assumed power, after a seven-month caretaker government, at the age of fifteen.

Monument to Charles XII in Stockholm, with Charles pointing towards Russia. Stockholmers call this statue "the lion among four pots" ("Lejonet mellan fyra krukor") referring to the mortars. This contrasts with a nearby statue of Charles XIII, which has lions similarly arranged; that statue is known as "the pot among four lions" ("Krukan mellan fyra lejon"), referring to a Swedish slang expression for a klutz.
