Editing 420 BC (section)

==== Greece ====
* The young and popular [[Alcibiades]] is elected "[[Strategos]]" (one of a board of ten generals) and begins to dominate [[Athens|Athenian]] life and politics. A Quadruple Alliance of [[Athens]], [[Argos, Peloponnese|Argos]], [[Mantineia]] and [[Ancient Elis|Elis]], which has been organised by Alcibiades (in opposition to [[Nicias]]) confronts a [[Sparta]]n-[[Boeotia]]n alliance.
