1. The origins of the Tudor dynasty
The House of Tudor became one of the most successful royal dynasties in British history, with a direct line passing from Henry Tudor to his son Henry VIII and his three children Edward VI, Mary I and Elizabeth I.
Yet this powerful dynasty which provided England with five sovereigns had its roots firmly in Welsh soil at a place called Penmynydd on the island of Anglesey. The Tudurs, to give them their original Welsh spelling, would go on to take their place in history, thanks to their son, Owain ap Maredudd ap Tudur – or Owen Tudor as he later became known.
But just how a commoner managed to marry into royalty and kick-start a dynasty beggars belief. It all began with an unlikely liaison between Catherine of Valois and a charismatic Welshman with a taste for adventure.
2. Birth of the Tudors
It would take just two generations for Owen Tudor's grandson Henry VII to be crowned the first Tudor king of England but getting there was no mean feat for the Tudur family of north Wales.
Historian Anna Whitelock looks at the changing fortunes of the Tudur family of Anglesey and the birth of Henry VII at Pembroke Castle.
3. The rise of Owen Tudor
Following the death of Henry V in 1422, Owen – by now a squire – was employed as Keeper of the Queen's Wardrobe. Legend has it that he accidentally fell onto the queen's lap during a drunken dance at court.
The pair became lovers and secretly married in around 1429. The first of their four children, Edmund, was born a year later.
Favoured by his step-brother, King Henry VI, Edmund was made the Earl of Richmond.
His younger brother Jasper became the Earl of Pembroke and crucially helped his young nephew Henry VII escape to France from Tenby during the Wars of the Roses.
The rights of Englishmen
Catherine and Owen chose to live away from court as their union was unpopular among the ruling classes.
Henry VI however continued to look after his step-father and in 1431 Owen was granted the 'rights of Englishmen' freeing him of the harsh penalties placed on his countrymen following the failed Welsh Wars of Independence.
He was now legally allowed to marry an Englishwoman, own land and bear arms.
The death of a queen
In 1437 Catherine retired to Bermondsey Abbey and gave birth to a baby girl but became gravely ill and died soon after.
With Catherine gone, news of Owen and Catherine's secret marriage reached the Duke of Gloucester and his allies.
Owen suddenly found himself vulnerable to outside forces bent on destroying him for his unlawful marriage and illegitimate children by the late queen.
4. A change in fortune
Having being pardoned and bailed by his step-son, King Henry VI, Owen Tudor's fortunes began to improve when he was moved into the royal household.
Historian Anna Whitelock looks at the changing fortunes of Owen Tudor following the death of his wife, Catherine of Valois, former queen of England.
Records show that by 1459 Owain ap Maredudd was increasingly referred to as Owen Tudor – an anglicised version of his name – incorporating his grandfather's surname. Why this happened is a mystery but the great Tudor dynasty could quite easily have been known as the (Maredudds) Merediths.

6. Owen's Tudor legacy
The people of Wales viewed the Battle of Bosworth as a Welsh victory, a fulfilment of the ancient Welsh prophecy that the Welsh would regain Britain from the Saxons. However, in reality, the Tudors kept their Welsh roots at arms length. After all, being Welsh wasn't popular at court.
Henry VII was only a quarter Welsh and his claim to the throne was due to his English mother, Lady Margaret Beaufort. In reality the succession of Tudor monarchs did very little for their countrymen.
The Acts of Union
The Acts of Union 1536 and 1543 passed by Henry VIII’s parliament had a profound effect on Welsh culture, forbidding anyone in authority to speak Welsh and making English the ‘natural mother tongue’.
While this helped the Welsh gentry who became equal to their English counterparts, the vast majority of the population were Welsh-speaking and the acts had a detrimental effect on the Welsh language and culture.
The Welsh Bible
Another Tudor monarch, Elizabeth I, introduced the Welsh Bible in 1588. The Welsh public may have perceived this as a gesture of kindness from the Tudor Queen to the people of her ancestral country.
In reality, the Protestant Elizabeth had a political motive behind the gift. Wales was historically a Catholic country and a Welsh Bible was a good way of spreading Protestantism in what was a strategically vulnerable area.
The Tudors may well have chosen to forget their Celtic roots for political gain but without the Tudurs of Penmynnyd, the great Tudor dynasty and some of England's most recognisable rulers would have ceased to exist.
