Eleanor of Castile, first queen consort of Edward I of England, died on November 28, 1290. She was married to Edward when she was but thirteen years of age. She bore to him sixteen children, of whom three were boys. Edward was the only son to live to adulthood and he eventually became King Edward II.
Eleanor is credited with having a system of reimbursement for the queen consort established, and this continued down through the years.
She and Edward had many adventures, and apparently were much enamored of each other. Following her death, Edward took her to London and at each stopover erected a cross in her memory. Very interesting history if you are into that sort of thing. Look it up.
