Römische Interessengemeinschaft Straubing, also known as COHORS-II-RAET, is a historical reenactment group focused primarily on presenting Roman history and culture from the first century AD. The group aims to give visitors an authentic experience through well-researched information and historically accurate portrayals. Its members consult specialist literature and expert opinions, maintain connections with museums and other institutions, and continually update their equipment as new historical findings emerge.

COHORS-II-RAET brings Roman history to life at events hosted by museums and schools, and takes part in Roman festivals. Its portrayals include figures such as Emperor Vespasian, who ruled from AD 69 until his death, and Antonia Caenis, a former enslaved woman and secretary to Antonia Minor. The organization’s website introduces its team, provides information about joining the group, and features a photo gallery and video content documenting past appearances. Through public events and educational presentations, the group shares its interest in Roman history with audiences and offers opportunities to explore its reenactment activities.
