The
History of the Peloponnesian War is a historical account of the
Peloponnesian War (431–404 BC), which was fought between the
Peloponnesian League (led by
Sparta) and the
Delian League (led by
Athens). It was written by
Thucydides, an
Athenian historian who also happened to serve as an Athenian general during the war. His account of the conflict is widely considered to be a classic and regarded as one of the earliest scholarly works of history. The
History is divided into eight books.
