Crowds and Power (original title Masse und Macht) is a 1960 book by Elias Canetti, dealing with the dynamics of crowds and "packs" and the question of how and why crowds obey rulers. Canetti draws a parallel between ruling and paranoia. Also, the memoirs of Daniel Paul Schreber are analyzed with an implicit critique of Sigmund Freud.
The book was translated from the German by Carol Stewart in 1962.
