De Bellis Antiquitatis or DBA (English: Of the Wars of Antiquity) is a fast play set of rules for the hobby of historical miniature wargaming, particularly ancient and medieval wargaming in the period 3000 BC to 1485 AD. These rules allow entire armies to be represented by less than 50 figures. The rules also include a campaign system and over 200 army lists. DBA is produced by the Wargames Research Group and was the first game in the DBx series, which now includes De Bellis Multitudinis (DBM, a more complex version of DBA), De Bellis Magistrorum Militum (DBMM, a successor or alternative to DBM), Hordes of the Things (a fantasy version), and De Bellis Renationis (DBR, a Renaissance version). An online video game titled DBA Online was also created.
