An evaluation of Zenobia is difficult; the queen was courageous when her husband's supremacy was threatened and by seizing the throne, she protected the region from a power vacuum after Odaenathus' death. According to Watson, she made what Odaenathus left her a "glittering show of strength". In the view of Watson, Zenobia should not be seen as a total powermonger, nor as a selfless hero fighting for a cause; according to the historian David Graf, "She took seriously the titles and responsibilities she assumed for her son and that her program was far more ecumenical and imaginative than that of her husband Odenathus, not just more ambitious".
