Ulrika Eleonora of Sweden

Ulrika Eleonora or Ulrica Eleanor (23 January 1688 – 24 November 1741), known as Ulrika Eleonora the Younger, reigned as Queen of Sweden from 5 December 1718 until her abdication on 29 February 1720 in favour of her husband Frederick. Following her husband's accession as King Frederick I, Ulrika Eleonora served as his queen consort until her death in 1741.

Ulrika Eleonora was the youngest child of King Charles XI and Ulrika Eleonora of Denmark and named after her mother. In 1715, she married Frederick of Hesse-Kassel. After the death of her brother Charles XII in 1718, Ulrika Eleonora claimed the throne. Her deceased older sister, Hedvig Sophia, had left a son, Charles Frederick of Holstein-Gottorp, who had the better claim by primogeniture. Ulrika Eleonora asserted that she was the ''closest'' surviving relative of the late king (the idea of proximity of blood) and cited the precedent of Queen Christina. She was recognized as successor by the Riksdag after she had agreed to renounce the powers of absolute monarchy established by her father. She abdicated in 1720, at which time her husband became king. Provided by Wikipedia
