Agaja is credited with introducing many features of the Dahomey state that became defining characteristics for future kings. It is often said that Agaja created the "Mehu" (a prime minister), the "Yovogan" (chief to deal with Europeans), and other administrative positions. However, oral traditions sometimes ascribe these developments to other kings. In addition, Agaja is sometimes credited as the king who created the Dahomey Amazons, a military unit composed entirely of women. Multiple histories account that Agaja did have armed female bodyguards in his palace and that he did dress women in armor in order to attack Whydah in 1728; however, historian Stanley Alpern believes that the Amazons were not likely fully organized during his reign.
