There is a reason chess evolved the way it did:
…we find that queenly reigns participated more in inter-state conflicts, without experiencing more internal conflict. Moreover, the tendency of queens to participate as conflict aggressors varied based on marital status.
Among married monarchs, queens were more likely to participate as attackers than kings. Among unmarried monarchs, queens were more likely to be attacked than kings. These results are consistent with an account in which queens relied on their spouses to manage state affairs, enabling them to pursue more aggressive war policies. Kings, on the other hand, were less inclined to utilize a similar division of labor.
This asymmetry in how queens relied on male spouses and kings relied on female spouses strengthened the relative capacity of queenly reigns, facilitating their greater participation in warfare.
