I can see there are many here who are interested in feudal Japan, and perhaps also samurai.
Here is a good link, I have spent some time on it to recap and there are good summaries and it is very user-friendly.
The only minus is: It seems to be still under construction, or, the creators of the site seem to have missed some topics, names etc...however, very good site if you want to pass the time and just get a summary on stuff.
