A light read, think of this book as an index of sorts, for when you eventually want to narrow your reading with an in-depth biography on "women who ruled."
Offhand, I wouldn't say these were "History's 50 Most Remarkable Women." A good number of them were in positions of power only because they had wimps for partners. China alone had two horrid empresses who started out as third class concubines who end up controlling the kingdom thanks to a combination of weakness, ineptitude, and apathy in their partners. And they made even more horrific mothers. Nothing remarkable about that.
A small percentage here also found themselves occupying seats of power only because their male blood relations (fathers, brothers, uncles) or spouses died during their reign or time in office. Sirimavo Bandaranaike, Indira Gandhi (no relation to Mahatma, it turns out, as Indira's married name was originally spelled Gandhy) and Benazir Bhutto come to mind. Or abdicated, as in the case of Elizabeth II, whose uncle, the Prince of Wales, chucked the monarchy in favor of his twice-married paramour, paving the way for her reluctant father. Others still were their fathers' or patrons' pawns in the Machiavellian plays for power (even though some of them predate Machiavelli): Isabella the "She-Wolf" and Lucrezia Borgia and Caterina Sforza were indeed different shades of remarkable: Isabella for what she did to her husband, Lucrezia for what she supposedly did with her brother, and Caterina, for what she was about to allow her enemies to do with her kids, prompting even Machiavelli to write about it! Using this yardstick, the writer overlooked Agrippina the Younger, Nero's mother, who should have been in that bunch. But most undeserving to be called "remarkable" would be Mary Queen of Scots and Sweden's fickle dilettante, Queen Christina. And Bathsheba. What exactly did she accomplish by her moonlit skinny-dipping, apart from having her husband killed so she could canoodle with the king?
Which is not to say that all those who inherited their positions through the same channels did too badly. Deserving special mention here are Boudica of Britain, Zenobia of Palmyra, Theodora of Byzntium, Cleopatra of Egypt, and Livia of Rome. Even Tomyris of Massagetae. Props too, to Queens Victoria and Elizabeths I and II. Especially Elizabeth I.
But topping my list are two women who owed their positions to no man--they came to power by virtue of their own merits. First runner-up would be the Oxford Chemistry grad Margaret Thatcher, and my overall winner for the epitome of remarkable in its truest translation of the word, which is to say she is "worthy of being or likely to be noticed especially as being uncommon or extraordinary," Golda Meir. And lastly, a special award goes to the woman whose husband owed his position to her: Eva Duarte Peron.
