Julius Caesar's "veni, vidi, vici" was not associated with a
city. It was associated with the kingdom of Pontus (in
north-eastern Turkey) rather than a city. When the Romans were
fighting the civil war between the forces of Caesar and the senate,
Pharnaces II, the king of Pontus, took advantage of this to seize
neighbouring Colchis and Lesser Armenia. Caesar undertook a rapid
march on Pontus and swiftly defeated Pharnaces at the Battle of
Zela (47 BC). His five-day campaign so swift and his victory so
complete that Caesar said "Veni, vidi, vici" (I came, I saw, I
won).
The sentence was also meant to be a snide remark about Pompey
the Great, his enemy in the civil war. Sixteen year earlier, Pompey
had struggled to defeat another king of Pontus in the Third
Mithridatic War (73-63 BC) whereas he defeated Pontus quickly and
easily. Caesar put Pompey's reputation as a great general into
question. Caesar had also defeated Pompey at the Battle of
Pharsalus a year before his defeat of Pharnaces. The ancient
historian Suetonius said that these three words were deployed in
the triumphal ceremony in Rome which celebrated this victory.
The Battle of Zela took place near Zela, which is now Zile, in
the Tokat Province of Turkey.
