It's never explicitly stated why or how Newman became the arch nemesis of Jerry in Seinfeld but it's very clear there is a history there.

No character in Seinfeld, not even Elaine, takes as much pleasure in seeing Jerry fail. At one point Jerry refers to Newman as being "pure evil" but he does concede that "he is Merry!".
Newman appears in 44 episodes of Larry David and Jerry Seinfeld's immortal sitcom and is often the highlight of any scene he appears in. He is the most recurring speaking character in the show outside of the main four characters and his chemistry with Michael Richards' Kramer should probably have led to a spin-off comedy somewhere down the road.
