Matilda was the daughter and heiress of King Henry I, wife of the Holy Roman Emperor and later of the Count of Anjou, mother of Henry II, the first Plantagenet King of England and she was Lady of the English and should have been Queen. She did not succeed herself but ultimately won as she put her son on the throne. She could have been a power behind her son's throne however she was outshone by the most brilliant and extraordinary woman of her time: Eleanor of Aquitaine, a most powerful duchess in her own rights, former Queen Consort of France and now Queen of England.
Yes, there was quite of injustice with regards to female rulers at the time and the prejudices against woman in power (not that our time this in an unknown phenomenon!) played against her. But one can not help it to feel that she may be had more pretensions than actual talent. There is something haughty and unlike able about her.
But judge for yourself. This book is an excellent and a great read. I enjoyed it very much
