Was there any flaws in Queen Nzinga's rule?

Queen Nzinga's rule, while marked by her diplomatic acumen and resistance against Portuguese colonization, had some flaws. Her reliance on alliances with European powers sometimes backfired, leading to internal conflicts and weakened regional ties. Additionally, her military strategies, though innovative, occasionally resulted in heavy losses for her forces. Despite her strong leadership, these factors complicated her efforts to maintain stability and autonomy in her kingdom.
