Charles XI or Carl (Swedish: Karl XI; 4 December [O.S. 24 November] 1655 – 15 April [O.S. 5 April] 1697) was King of Sweden from 1660 until his death in 1697.
He was the only son of King Charles X Gustav and Hedwig Eleonora of Holstein-Gottorp. His father died when he was four years old, so Charles was educated by his governors until his coronation at the age of seventeen. Soon afterward, he was forced out on military expeditions to secure the recently acquired dominions from Danish troops in the Scanian War. Having successfully fought off the Danes, he returned to Stockholm and engaged in correcting the country's neglected political, financial, and economic situation. He managed to sustain peace during the remaining 20 years of his reign.
