The restoration of Edward IV in 1471 is sometimes seen as marking the end of the Wars of the Roses proper.

Peace is restored for the remainder of Edward's reign.

His youngest brother, Richard, Duke of Gloucester, and Edward's lifelong companion and supporter, William Hastings, are generously rewarded for their loyalty, becoming effectively governors of the north and midlands respectively.

The reinstated king also restores his brother Clarence to royal favor.

As his father-in-law had died, Clarence becomes jure uxoris Earl of Warwick, but does not inherit the entire Warwick estate as his younger brother, Richard, Duke of Gloucester, marries Anne Neville, the widowed younger sister of Clarence's wife.

Clarence on March 25, 1472, is created 1st Earl of Warwick.

With the deaths of Somerset and his younger brother, the House of Beaufort, who are distant cousins of Henry VI and had a remote claim to succeed him, has been almost exterminated.

Only the female line of Somerset's uncle, the 1st Duke of Somerset, remains, represented by Lady Margaret Beaufort and her son Henry Tudor.

Henry escapes from Wales with Jasper Tudor, his paternal uncle, and remains in exile in Brittany for the remainder of Edward's reign.

The year after the Battle of Tewkesbury however, Lady Margaret marries Lord Stanley, one of King Edward's supporters, who will later turn against Edward's brother Richard of Gloucester when he becomes King as Richard III, and will be instrumental in putting Henry Tudor on the throne.

Clarence's wife Isabel had in 1475 given birth to a son, Edward, later Earl of Warwick.

She died on December 22, 1476, two months after giving birth to a short-lived son named Richard, and they are buried together at Tewkesbury Abbey in Gloucestershire.

Their surviving children, Margaret and Edward, will be cared for by their aunt, Anne Neville, until she dies in 1485, when Edward is ten years old.

Though most historians now believe Isabel's death was a result of either consumption or childbed fever, Clarence is convinced she had been poisoned by one of her ladies-in-waiting, Ankarette Twynyho, whom, as a consequence, he has judicially murdered in April of 1477, by summarily arresting her and bullying a jury at Warwick into convicting her of murder by poisoning.

She is hanged immediately after trial with John Thursby, a fellow defendant.

Clarence's mental state, never stable, deteriorates from this point and leads to his involvement in yet another rebellion against his brother Edward.

The arrest and committal to the Tower of one of Clarence's retainers, an Oxford astronomer named Dr. John Stacey, leads to his confession under torture that he had 'imagined and compassed' the death of the King, and used the black arts to accomplish this.

He implicates one Thomas Burdett, and one Thomas Blake, a chaplain at Stacey's college.

All three are tried for treason, convicted, and condemned to be drawn to Tyburn and hanged.

Blake is saved at the eleventh hour by a plea for his life from James Goldwell, Bishop of Norwich, but the other two are put to death as ordered.

This is a clear warning to Clarence, which he chooses to ignore.

He appoints Dr. John Goddard to burst into Parliament and regale the House with Burdett and Stacey's declarations of innocence that they had made before their deaths.

Goddard is a very unwise choice, as he is an ex-Lancastrian who has expounded Henry VI's claim to the throne.

Edward summons Clarence to Windsor, severely upbraids him, accuses him of treason, and orders his immediate arrest and confinement.

Clarence is imprisoned in the Tower of London and put on trial for treason against his brother Edward IV.

Clarence is not present—Edward IV himself prosecutes his brother, and demands that Parliament pass a Bill of Attainder against his brother, declaring that he is guilty of 'unnatural, loathly treasons' which were aggravated by the fact that Clarence was his brother, who, if anyone did, owed him loyalty and love.

Following his conviction, he is "privately executed" at the Tower on February 18, 1478, by tradition in the Bowyer Tower, and soon after the event, the rumor gains ground that he had been drowned in a butt of Malmsey wine.

Shortly afterward, his son Edward Plantagenet is created Earl of Warwick.
