Elizabeth of York
Elizabeth of York (11 February 1466 – 11 February 1503) was the first queen consort of England of the Tudor dynasty from 18 January 1486 until her death, as the wife of Henry VII.
She married Henry in 1485 after his victory at the Battle of Bosworth Field, which marked the end of the Wars of the Roses.
Together, Elizabeth and Henry had seven, possibly eight, children.
After the death of her father, King Edward IV, Elizabeth's brothers
the "Princes in the Tower" disappeared, their fate uncertain.
Although the 1484 act of Parliament "Titulus Regius" declared the marriage of her parents, Edward and Elizabeth Woodville, invalid, she and her sisters were subsequently welcomed back to court by Edward's brother, King Richard III.
As a Yorkist princess, the final victory of the Lancastrian faction in the War of the Roses may have seemed a further disaster, but Henry Tudor knew the importance of Yorkist support for his invasion and promised to marry Elizabeth before he arrived in England.
This may well have contributed to the hemorrhaging of Yorkist support for Richard.
Although Elizabeth seems to have played little part in politics, her marriage appears to have been a successful one.
Her eldest son Arthur, Prince of Wales, died at age 15 in 1502, and three other children died young.
Her second, and only surviving, son became King Henry VIII of England, while her daughters Mary and Margaret became queen of France and queen of Scotland, respectively; many modern royals, including Elizabeth II, trace their line through Margaret.
