R.U.R. is a 1920 science fiction play by the Czech writer Karel Čapek. "R.U.R." stands for Rossumovi Univerzální Roboti (Rossum's Universal Robots,[1] a phrase that has been used as a subtitle in English versions).[2] The play had its world premiere on 2 January 1921 in Hradec Králové;[3] it introduced the word "robot" to the English language and to science fiction as a whole.[4]R.U.R. became influential soon after its publication.[5][6][7] By 1923, it had been translated into thirty languages.[5][8]R.U.R. was successful in its time in Europe and North America.[9] Čapek later took a different approach to the same theme in his 1936 novel War with the Newts, in which non-humans become a servant-class in human society.[10]
