Diploma

• The Diploma, also known as a ‘Missio’, was a Roman military discharge certificate inscribed on a Bronze Tablet.
• It was awarded after 25 years of military service.

Right of Marriage

• For Legionaries, the Diploma also conferred the right of Conubium or Marriage.
• During the first two centuries CE, the Roman soldier was not officially allowed to  marry until discharged.
• In practice, many soldiers had common law families, living close to the Fortress, but they were not recognised by the State until after the soldier had retired.

Roman Citizenship

• For the Roman Auxiliaries, after 25 years Service, the Diploma also conferred Roman Citizenship, as well as the right of Conubium (Marriage).

Entry to the Equestrian Class

• During the Empire, every year, thirty Primus Pilus centurions were promoted into the Equestrian class on retirement and receipt of their Diploma.
