Katherine Swynford, Royal Mistress

Katherine Swynford (c.1350? - 10 May 1403) was the daughter of a knight from Hainaut. Her father, Paon de Roet (his and Katherine's arms are shown), followed Philippa of Hainaut when she came to England to marry King Edward III. Katherine was a lady-in-waiting to the queen.

Just as kings found advantageous marriages for their offspring, so did they help their favorites marry well. Katherine Roet was married to Hugh Swynford, a knight in the retinue of John of Gaunt. Accordingly, Katherine was transferred to the household of Gaunt's wife, Blanche. When Blanche died in 1368, Katherine became lady-in-waiting to her daughters, Philippa and Elizabeth. Katherine and Hugh had three or four children.

In the same year that Hugh Swynford died, 1371, John of Gaunt married Constance of Castile and returned to England from the continent. Katherine was now lady-in-waiting to Constance, the new Duchess of Lancaster and also styled Queen of Castile. Katherine now had a little more to her name: Hugh was not wealthy, but the king and Gaunt made sure his estates in Lincolnshire became Katherine's (Hugh's son and heir being a minor, the estates would have become property of his overlords, the king and Gaunt). Gaunt also increased her annuity from 20 to 50 marks, a very decent sum, to help the upkeep of the estates.

In 1373, Katherine had a child, John Beaufort (the surname came from one of Gaunt's estates in Hainaut). The father was John of Gaunt. They had three more children, all while Constance of Castile was still alive. Gaunt did not exactly keep the relationship quiet: he gave Katherine an annuity and several estates as a sign of his favor. 

Knowing that Katherine was the favorite of Gaunt (the most powerful man in England after the king), many would try to curry favor with her. The mayor of Leicester gave her a gift of 16 shillings' worth of wine, recorded as to "Lady Katherine Swynford, mistress of the Duke of Lancaster." That was in August 1375 and is the first public acknowledgement of the affair. The public in general, however, was appalled at the behavior, and the two were forced to break off the affair in 1381. Katherine left her position as lady-in-waiting to the woman whose husband she was sleeping with and settled in Lincoln, likely the Kettlethorpe estate from her deceased husband.

What did Constance think of this affair? Did she know? Gaunt was her best option for getting to the Castilian throne that had been usurped from her father, so she may have taken the bad with the potential good. Her Castilian ladies-in-waiting, however, likely noticed and complained: in 1373 they were all sent by Gaunt to Nuneaton Priory, a Benedictine monastery many days' journey from London. (They were allowed back a year later.)

Katherine was not completely personae non grata, however. King Richard II made her a Lady of the Garter in 1387. She also was brought back into royal service, so to speak, by joining the household of Mary de Bohun, Gaunt's daughter-in-law by virtue of marriage to his eldest son, Henry Bolingbroke (the future King Henry IV).

Constance of Castile, Duchess of Lancaster, died 24 March 1394 and was buried in Leicester. Gaunt and Katherine were now free to pursue an open relationship. They were still haunted by the scandal, and the shadow of adultery. 

How they handled it, and what happened after, will be tomorrow's topic.

John of Gaunt

John of Gaunt (6 March 1340 - 3 February 1399) was a highly influential man in adulthood. He was the third son of Edward III and Queen Philippa, born while the queen was in Ghent in Flanders (called "Gaunt" in English). (Actually, he was the 4th son, but an earlier son had died after a few weeks, years before John was born.)

In the 1350s, he was raised in the household of his older brother Edward of Woodstock (later known as the Black Prince). Accounting records showed that John had two "Saracen" companions named Sigo and Nakon.

He spent much of his youth in France and Spain where he took part heavily in the "family business," which was fighting France in the Hundred Years War. Edward tried (as kings do) to arrange advantageous matches for his children, and for John he arranged a marriage to Blanche of Lancaster in 1359. Blanche was not only a great beauty, but her father was the powerful first Duke of Lancaster, Henry of Grosmont. (Trivia: both John and Blanche had King Henry III as their great-great-grandfather, making them third cousins.)

John's father-in-law died in 1361, and a year later Edward made John the Duke of Lancaster and gave him half Henry of Grosmont's lands. He inherited even more land when his wife's sister, Maud the Countess of Leicester, died childless in 1362. At this point John owned land in almost every county in England and 30 castles. The rents from these properties flowing upward to John gave him an income of £8,000 - £10,000 annually (the buying power of about $200 million today), and allowed him to maintain a lifestyle comparable to a king's.

In 1370 he took a small army to Aquitaine to reinforce his older brother Edward, whose health was beginning to suffer. John was left in charge while Edward returned to England. In September 1371, John returned to England, but not before re-marrying. Blanche had died in 1368. This time, John married Constance of Castile, daughter of Peter the Cruel. Peter had been king of Castile, but was killed in 1369 by his half-brother Henry. John felt that Constance gave him a potential claim to the throne of Castile. He even introduced her to England as Queen of Castile and tried to style himself King of Spain, or at least "my lord of Spain," but no one was buying it. Ultimately, his and Constance's daughter Catherine married Henry II's son, Henry III of Castile, settling the matter of Castilian succession.

Now I'd like to jump to John's third wife, even though we haven't discussed the death of his second; yes, that's an important clue to what's to come. See you next time.
