Since Shakespeare wasn't born until 1564 and Richard III died in 1485, they didn't actually "know" each other personally. Instead, one of Shakespeare's most well known plays is based on the life of Richard III.
According to William Shakespeare, Richard III had a hump back.
The phrase "A horse! a horse! my kingdom for a horse!" is famously uttered by Richard III in William Shakespeare's play, Richard III. It reflects Richard's desperation in battle, where he is willing to trade his kingdom for a horse to save his life.
