Crusading at it's Height

I've been looking at many websites for information but I found that lots are just too much to take in at once; almost like there way to spread out over the place or too random or they just aren't clear enough. Anyway, I found this website that is very clear and gives some really helpful information. Also, lots of the links here are primary sources!
Hope it helps!
