The Persians (Greek: Πέρσαι, Latin Persae) by Aeschylus is the oldest surviving Greek tragedy and the only one to deal with recent historical events, portraying the Persian court during Xerxes' invasion of Greece, which ended with defeat at Salamis and Plataea in 480 BC. The play was produced at Athens only eight years later in 472 BC, with the statesman Pericles acting as choregos or producer. Aeschylus himself was a veteran of the Persian Wars, fighting at Marathon in 490 BC. The tone of the work is one of compassion for the defeated mixed with pride in the Greek victory.
