Nikiasfrieden
After the two generals who opposed peace, the Athenian Cleon and the Spartan Brasidas, were slain in battle, Nicias decided to seek peace between all the warring states. Nicias, and Pleistoanax, King of Sparta, negotiated in 421 BC the Peace of Nicias between Athens and Sparta, which brought a temporary end to the Peloponnesian War.
