Civic Crown
The Civic Crown (Latin: corona civica) was a chaplet of common oak leaves woven to form a crown. During the Roman Republic and the subsequent Principate, it was regarded as the second highest military decoration to which a citizen could aspire (the Grass Crown being held in higher regard). It was reserved for Roman citizens who saved the lives of fellow citizens by slaying an enemy on a spot held by the enemy that same day. The citizen saved must admit it; no one else could be a witness.
After Sulla's constitutional reforms, any recipient of the Civic Crown was entitled entry into the Roman Senate. Furthermore, the recipient was required by law to wear his crown at every public gathering, and was applauded even by men much senior to himself. It later became a prerogative for Roman Emperors to be awarded the Civic Crown (originating with Augustus, who was awarded it for saving the lives of citizens by ending the series of civil wars).
Pliny wrote about the Civic Crown at some length in Naturalis Historia:
