House of Tudor - Ascent To The Throne

Ascent To The Throne

The Tudors descended on Henry VII's mother's side from John Beaufort, one of the illegitimate children of the 14th century English Prince John of Gaunt, 1st Duke of Lancaster (the third surviving son of Edward III of England) by Gaunt's long-term mistress Katherine Swynford. The descendants of an illegitimate child of English Royalty would normally have no claim on the throne, but the situation was complicated when Gaunt and Swynford eventually married in 1396, when John Beaufort was 25. The church retroactively declared the Beauforts legitimate by way of a papal bull the same year, confirmed by an Act of Parliament in 1397. A subsequent proclamation by John of Gaunt's legitimate son, King Henry IV, also recognised the Beauforts' legitimacy, but declared them ineligible ever to inherit the throne. Nevertheless, the Beauforts remained closely allied with Gaunt's legitimate descendants from his first marriage, the Royal House of Lancaster.

John Beaufort's granddaughter Lady Margaret Beaufort, a considerable heiress, was married to Edmund Tudor, 1st Earl of Richmond. Tudor was the son of Welsh courtier Owen Tudor (Welsh: Owain ap Tewdwr) and Katherine of Valois, widowed Queen Consort of the Lancastrian King Henry V. Edmund Tudor and his siblings were either illegitimate, or the product of a secret marriage, and owed their fortunes to the good will of their legitimate half-brother King Henry VI.
