A liberty pole is a wooden pole, or sometimes spear or lance, surmounted by a "cap of liberty", mostly of the Phrygian cap. The symbol originated in the immediate aftermath of the assassination of the Roman dictator Julius Caesar by a group of Rome's Senators in 44 BCE. Immediately after Caesar was killed the assassins, or Liberatores as they called themselves, went through the streets with their bloody weapons held up, one carrying a pileus carried on the tip of a spear. This symbolized that the Roman people had been freed from the rule of Caesar, which the assassins claimed had become a tyranny because it overstepped the authority of the Senate and thus betrayed the Republic.

The Phrygian cap or liberty cap is a soft conical cap with the apex bent over, associated in antiquity with several peoples in Eastern Europe and Anatolia, including the Persians, the Medes and the Scythians, as well as in the Balkans, Dacia, Thrace and in Phrygia, where the name originated. The oldest depiction of the Phrygian cap is from Persepolis in Iran.
