Uncivilized does not mean stupid or brutes.
Yet the presence of gathering places certainly does suggest civility! A warlord could command the cooperation necessary perhaps, but would have little reason to build that structure rather than walls and towers
any examples of women warlords ? I'm interested because both gendering and not gendering that sentence would upset feminists and I can't tell if this is trolling or whether more thought went into why gendering felt like the safe bet here.
Standout for me: Ching Shih (China, 1775–1844), Njinga of Ndongo and Matamba (Angola, c. 1583–1663), Zenobia (Palmyrene Empire, 3rd century CE), Trưng Trắc and Trưng Nhị (Vietnam, 1st century CE), Æthelflæd, Lady of the Mercians (England, c. 870–918).
Some honorable mentions: Boudica, Khutulun, Rani Lakshmibai, Grace O’Malley.
