In 202, Emperor Septimius Severus returns to Rome after a five-year absence. Festivals are held to celebrate his six-year reign. Severus undertakes changes in the imperial government, giving the Roman army a dominant role, raising pay in the legions and permitting legionaries to marry in order to secure their loyalty.
Rome establishes medical licenses, awarded only to trained physicians who have passed examinations. Medical societies and civic hospitals are set up, and laws are passed to govern the behavior of medical students. They are prohibited from visiting brothels.
