Christina (Swedish: Kristina, 18 December 1626 – 19 April 1689), a member of the House of Vasa, was Queen of Sweden in her own right from 1632 until her abdication in 1654. She succeeded her father Gustavus Adolphus upon his death at the Battle of Lützen in 1632, but began ruling the Swedish Empire when she reached the age of eighteen in 1644.
