Ulrika Eleonora, Queen of Sweden (d. 1741)
Ulrika Eleonora or Ulrica Eleanor (23 January 1688 – 24 November 1741), known as Ulrika Eleonora the Younger, was Queen of Sweden, reigning in her own right from 5 December 1718 until her abdication on 29 February 1720 in favour of her husband King Frederick, and then as his consort until her death.

She was the youngest child of King Charles XI and Ulrika Eleonora of Denmark and named after her mother. After the death of her brother King Charles XII in 1718, she 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 in favor of her husband, Landgrave Frederick I of Hesse-Kassel.
