Battle context
The Battle of Sybota, fought in 433 BC between Corcyra and Corinth, stands as one of the immediate catalysts for the Peloponnesian War. The engagement drew in competing interests that sharpened the divisions between the Athenian and Spartan alliance systems, accelerating the broader conflict that would consume the Greek world for nearly three decades. Corcyra's recorded casualties of 1,000 indicate a substantial and costly confrontation. The battle's role as a direct precursor to the Peloponnesian War places it among the critical pre-war incidents that forced the major powers to commit to positions from which large-scale conflict became unavoidable.
