11 Jul 1469 Calais: Marriage of George Duke of Clarence and Isabel Neville
Edward IV King England's marriage to Elizabeth Woodville caused Warwick The Kingmaker to change sides from York to Lancaster. It isn't clear why he did so.
Before the announcement of Edward's marriage at the Privy Council in 1464 Warwick &had been negotiating with the French for Edward to marry a French princess which implies he wasn't considering either of his two daughters for marriage to Edward IV - even a daughter of an Earl isn't sufficiently noble for the wife of a King. English Kings traditionally married Princesses from France and Spain.
In Jul 1469 Warwick married his eldest daughter Isabel to King Edward IV's brother George Duke of Clarence. He had requested Edward approve this marriage previously without success - a younger brother married to the heiress of Warwick would be too powerful. Now he proceeded without Edward IV's authorisation.

22 Jul 1470 Angers Cathedral: Angers Agreement
Warwick, now firmly opposed to King Edward IV, agreed with Margaret of Anjou (King Henry VI's wife) that he, Warwick, would invade England and Warwick's youngest daughter Anne would marry King Henry VI's and Margarets son Edward of Westminster.
At Angers Cathedral Margaret is reported to have kept Warwick on his knees for a full twenty minutes before responding to him. Warwick was, after all, the cause of her husband being challenged for the throne. He had alot to apologise for.

03 Oct 1470 Re-adeption of Henry VI
Henry VI was re-adepted, or restored, to the crown of England. Henry was at this time affected by his long standing illness; he had to be led by the hand during his parade through London. It didn't last long. Six months after the re-adeption Edward IV landed at Ravenspur and, after the battles of Barnet and Tewkesbury, was restored to the throne.

14 Apr 1471 Battle of Barnet
George Duke of Clarence's defection to Lancaster was short-lived. Anne Neville's marriage to Edward of Westminster rather put George's marriage to Isabel Neville in the shade. Any hopes of Kingship were clearly second now to Edward of Westminster. George received and accepted an offer of reconcillation from King Edward IV.
Warwick "Kingmaker" was relying on George to add to his already large army. In the event George supported York. Even so Warwick's army was considerably larger than King Edward's.
The battle was fought in mist; visibilty was poor. At one point during the battle an incident of friendly fire was perceived as treachery resulting in a large contigent leaving the field. King Edward IV took full advantage of the confusion.
Warwick "Kingmaker" was killed, as was his brother John. Their bodies were displayed in St Paul's Cathedral for three days then buried in Bisham Abbey.

21 May 1471 Tower of London: Death of Henry VI
After the defining Battle of Tewkesbury there was little left of the Lancastrian cause. King Henry VI's son Edward of Westminster had been killed. Henry's wife Margaret captured. Its not clear whether Henry VI was murdered by Edward or died of natural causes. He was in his fifties. Most of the second half of his reign had been spent either captured or in a catatonic state. The House of Lancaster expired in the male line.

12 Jul 1472 St Stephen's Chapel: Marriage of Richard Duke of Gloucester and Anne Neville
Richard Duke of York, King Edward's youngest brother, future King Richard III married Anne Neville who had been widowed a year before at the Battle of Tewkesbury.
Unfortunately this brought Richard into competition with his older brother George who had enjoyed the whole of the inheritance of Richard Neville "Kingmaker"; Richard was now entitled to half.
Margaret was imprisoned first in Wallingford Castle, then the Tower of London. Eventually, in 1475, she was ransomed by King Louis XI. She spent the last seven years of her life living in relative obscurity.
29 Jul 1476 St Mary and All Saints (Fotheringay): Reburial of Richard and Edmund of York, and Edward of Norwich
The apotheosis of the reign of the House of York. King Edward IV's father and younger brother had both been killed at the Battle of Wakefield, Dec 1460, their heads displayed on Micklegate Bar (York) as seen by Edward of York as he triumphantly entered York after the Battle of Towton. King Edward IV had their remains buried at Fotheringay Church in full state.
Elizabeth I, who was descended from King Edward IV's daughter Elizabeth, queen consort of Henry VII, visited Fotheringay to find the tombs of her York ancestors exposed to the elements. She had the remains of Richard and Edmund, as well as that of Edward of Norwich (brother of Richard of Conisburgh, grand-father of King Edward IV) moved to new tombs inside the remaining part of Fotheringay Church.

18 Feb 1478 Bowyer Tower: Execution of George Duke of Clarence
George Duke of Clarence's wife Isabel died on 22 Dec 1476 two months after giving birth to Richard who died young. George was convinced of foul play. Blaming Isabel's lady in waiting Ankarette Twynyho he had her arrested and executed.
George requested to marry Mary, Duchess of Burgundy. King Edward IV refused. George left court.
Implicated in a plot for King Edward's IV murder George continued to challenge Edward.
King Edward IV had George Duke of Clarence arrested, imprisoned in the Tower of London, and tried for treason. Found guilty George Duke of Clarence was privately executed, traditionally, by being drowned in a butt of Malmsey wine.
George's two children who survived to adulthood, Margaret and Edward, were both executed for being from the House of York. Edward, the last of the legitimate male Planatagent line, was executed for his involvement in the Perkin Warbreck plot. The evidence was tenuous, and he had been in imprisoned in the Tower for most of his twenty four years. The Spanish were concerned that King Henry VII may be challenged by Edward discouraging them from allowing Prince Arthur to marry Catherine of Aragon. Henry's subsequent execution of Edward caused Catherine much angst believing it to be the reason for her many troubles. George's daughter Margaret's son Henry Pole was beheaded aged 24. Margaret was beheaded aged 67. All by Henry VIII.
