First coined by Martin Esslin, Theatre of Absurd, a class of literature consists of a pessimistic view of humanity struggling vainly to find a purpose and to control its fate. There is little dramatic action: however frantically the characters perform, their business serves to underscore the fact that nothing happens to change their existence . Language in such works is full of cliches, puns, repetitions, and non sequitur. The main figures who popularised this class include Arthur Adamov, Jean Genet, Harold Pinter, Eugene Ionesco, and Samuel Beckett.
