Richard Neville KG, 16th Earl of Warwick (November 22, 1428 – April 14, 1471), known as Warwick the Kingmaker, is an English nobleman, administrator, and military commander.

The son of Richard Neville, 5th Earl of Salisbury, Warwick is the wealthiest and most powerful English peer of his age, with political connections that go beyond the country's borders.

One of the main protagonists in the Wars of the Roses, he is instrumental in the deposition of two kings, a fact which later earns him his epithet of "Kingmaker".

Through fortunes of marriage and inheritance, Warwick emerges in the 1450s at the center of English politics.

Originally a supporter of King Henry VI, a territorial dispute with the Duke of Somerset leads him to collaborate with Richard, Duke of York,in opposing the king.

From this conflict, he gains the strategically valuable post of Captain of Calais, a position that benefits him greatly in the years to come.

The political conflict later turns into full-scale rebellion, and both York and Warwick's father, Salisbury, fall in battle.

York's son, however, later triumphs with Warwick's assistance, and was crowned King Edward IV.

Edward initially ruled with Warwick's support, but the two later fall out over foreign policy and the king's choice of partner in marriage.

After a failed plot to crown Edward's brother, George, Duke of Clarence, Warwick instead restores Henry VI to the throne.

The triumph is short-lived however: on April 14, 1471 Warwick is defeated by Edward at the Battle of Barnet, and killed.

Warwick has no sons.

The elder of his two daughters, Isabel, marries George, Duke of Clarence.

His younger daughter Anne, after a short-lived marriage to King Henry's son Edward of Westminster, who dies in battle at the age of 17, then marries King Edward's younger brother Richard, Duke of Gloucester, who later becomes King Richard III.

Warwick's historical legacy has been a matter of much dispute.

Historical opinion has alternated between seeing him as self-centered and rash, and regarding him as a victim of the whims of an ungrateful king.

It is generally agreed, however, that in his own time he enjoyed great popularity in all layers of society, and that he was skilled at appealing to popular sentiments for political support.
