What military leader is quoted as saying "I came, I saw, I conquered"?

The military leader quoted as saying “I came, I saw, I conquered” was Julius Caesar.

The original Latin phrase is “Veni, vidi, vici,” a famously concise report of victory. Ancient sources connect it with Caesar’s rapid defeat of Pharnaces II of Pontus at the Battle of Zela in 47 BC, in what is now Turkey. The wording emphasized that the campaign had been completed almost immediately.

The phrase was reportedly used in a message to the Roman Senate and later became associated with Caesar’s triumphal celebrations. Its three matching verbs—came, saw, conquered—give it the memorable rhythm that made it one of the best-known quotations from antiquity.

A common mix-up is treating the phrase as a general Roman motto or as a line from Shakespeare’s Julius Caesar. It is specifically attributed to the historical Julius Caesar, although the exact circumstances and wording survive through later ancient accounts.
