On average, women rulers with real power have had an outstandingly good record.
Wu Zetian 625-705
Isabel la Catolica 1451-1504
Queen Elizabeth the First 1533-1603
Angela Merkel 1954
The point is that not that women will invariably be better leaders than men. However, it is undeniably true that for those who have exercised power, the record of women has been infinitely superior to that of men. The first three rulers pictured above led their nations in the best years of their histories - Golden Ages. Angela Merkel may not lead Germany to a golden age but she is doing a great job so far. We are heading towards some very bad times indeed and our almost universally male leaders have done nothing substantive to turn the situation around. Can we learn something from this?
