No, there is no war in "Oedipus Rex" by Sophocles (495 B.C.E. -- 405 B.C.E.).
Specifically, the violence that occurs does not take place on the battlefield. Instead, there is a mental war of wits in which the loser Sphinx kills herself and the victor Oedipus becomes King of Thebes. That incident is preceded by a violent street brawl over a right-of-way that leaves five people dead. It subsequently is succeeded by the violent suicide of Oedipus' wife and by Oedipus' violent self-blinding.
"Rex" is Latin for "King". Oedipus Rex means "Oedipus the King".
Thebes is the setting of Oedipus Rex because it is the place where the story begins.
'King' is an English equivalent of 'Rex' in the play 'Oedipus Rex'.
The shepherd in Oedipus Rex is the person who rescues Oedipus Rex as a child. The shepherd also confirms the main character's fate.
