Historathon is a reading challenge originating from BookTube (this guy: @revenantreads)

Each quarter of the year you have to read non-fiction history books dealing with a corresponding time period in history:

Q1: Prehistory and ancient history (prehistory-500)
Q2: Middle ages (500-1500)
Q3: Early modern (1500-1820)
Q4: Modern (1820-present)

Add as many books to each quarter as you like, the more the better!
