People have always endeavored to make the most out of their connections. We've all heard the saying, "it's not necessarily what you know, but who you know." Certainly this is evident throughout history. A man or woman could rise rapidly from gaining the eye or attention of those in power. For men, a deed well done, the ability to command men or prove worthy in battle brought him to the forefront. Women often played a more passive part, being desired for the wealth or beauty they possessed.
The rewards of royal favor could result in gifts, as well as titles and lands that resulted in power and income. It seems that with so much to gain there would be no question as to whether you'd want to seek the lord's favor and be right grateful for catching his eye. Not always so. Drawing favor wasn't always welcomed and could more times than not, end up being be paid for in the bestower's own coin. Those who fell from favor often paid with their lives.
In 1214, Matilda Fitzwalter caught the eye of King John, successor and brother to King Richard, the Lionheart. John was used to taking what he liked and known for his terrible Plantagenet temper. When Matilda was repulsed by the King's advances, John had her held in the northeastern turret of the White Tower.
The King, it seems, was determined to get under her skin one way or another. He had a poisoned egg sent to her during her confinement. It killed her.
