The early 20th century is often referred to as the "Golden Age" of Czech fantasy. During this period, Czech writers and artists began to draw inspiration from their folklore heritage, creating works that blended traditional mythology with modern literary styles. One of the most notable authors of this era was Karel Čapek, a science fiction and fantasy writer who is best known for coining the term "robot" in his 1920 play "R.U.R." (Rossum's Universal Robots).
