This page is for you. A lot of the information on my website is very detailed. Here's a quick refresher course on the basics of the outlaw, his friends, foes and other general information. There are lots of different Robin Hood stories out there.
Storytellers continue to add new stories and new characters to the legend.
For example, the early stories say Robin Hood was not a nobleman. Now he often is one. Marian and Tuck weren't in the earliest tales. This page summarizes some of the most common elements of the legend. Many of the stories here contradict each other.
