誰が エドマンド・テューダー (リッチモンド伯) と結婚しましたか？

初代リッチモンド伯エドマンド・テューダー（Edmund Tudor, 1st Earl of Richmond, 1430年頃 - 1456年11月1日）は、イングランドの貴族。オウエン・テューダーとキャサリン・オブ・ヴァロワ（フランス王シャルル6世の娘でヘンリー5世の未亡人）の長男でベッドフォード公ジャスパー・テューダーの兄、ランカスター朝最後の国王であるヘンリー6世の異父弟、テューダー朝の始祖である国王ヘンリー7世の父。

Lady Margaret Beaufort ( BOH-fərt or BEW-fərt; 31 May 1443 – 29 June 1509) was a major figure in the Wars of the Roses of the late 15th century, and mother of Henry VII of England, the first Tudor monarch. She was also a second cousin of Henry VI, Edward IV and Richard III of England.

A descendant of King Edward III, Lady Margaret passed a disputed claim to the English throne to her son, Henry Tudor. Capitalising on the political upheaval of the period, she actively manoeuvred to secure the crown for her son. Margaret's efforts ultimately culminated in Henry's decisive victory over King Richard III at the Battle of Bosworth Field. She was thus instrumental in orchestrating the rise to power of the Tudor dynasty. With her son crowned Henry VII, Margaret wielded a considerable degree of political influence and personal autonomy. She was also a major patron and cultural benefactor during her son's reign, initiating an era of extensive Tudor patronage.

Margaret is credited with the establishment of two prominent Cambridge colleges, founding Christ's College in 1505 and beginning the development of St John's College, which was completed posthumously by her executors in 1511. Lady Margaret Hall, Oxford, a 19th-century foundation named after her, was the first Oxford college to admit women.
