Gaius Marius was supposed to have won the civic crown 3 times. The civic crown was only won for exceptional valour. The grass crown was very rarely won. Winners of the Grass Crown were Publius Decimus Mus, Scipio Africanus, Quintus Fabius Maximus Cuncator, Quintus Sertorius, Lucius Cornelius Sulla and a Gaius Fonteius. Under Sulla's laws, any winner of a grass or civic crown was adlected automatically to the senate. Which indicates even the civic was rarely won. Caesar won the civic becaue he reportedly saved a cohort thru his valour. Becauseof this he became a senator at age 20.
