How to Be a Dictator: The Cult of Personality in the Twentieth Century by Frank Dikötter
A good overview of 8 dictators of the 20th century that heavily relied on their 'cult of personality' to hold onto power. I read a lot of history, so for me this book felt light to me. The chapters on Hitler and Mao Zedong weren't all that revealing to me as I have read a lot about those dictators. The other chapters were more interesting to though.
