1. William Marshal (1146-1219, English)
William Marshal is the greatest knight of the middle ages because he satisfied all the virtues of knighthood despite the odds against him. He was immensely skillful with all sorts of arms; was loyal to his lord; defended the faith gallantly; won the favor of a great woman; was the most famous knight of his times and thereafter; was respected, diplomatic and merciful. He made his mark kicking the steel pants of all comers at the many tournaments held during his day, and that didn’t mean he won crummy trophies; no, he literally kicked ass and took names – so that he could ransom those defeated knights with their families. Aside from actual battle, the tournament was the one place a knight could enjoy combat, be seen by his betters, and display his prowess. And with the money William bought better arms and land, on top of gaining prestige.
