Have you graduated college? I got my bachelors in 2016.

I am still doing my bachelors actually. The term "bachelor" used to refer to a knight bachelor who was too poor or young to father vassals under his own banner.

Wow. I never knew that.  What other titles did knights have back in the day?

A few other I can't think of right now. But by the end of the 13th century, the term was used by junior members of guilds or universities.

What types of guilds were there then?
