Adaptations to children's and young people's theater have arrived late to Spain. The pioneer country in it (with Shakespeare at the head thanks to the Lamb brothers) is at the forefront and there children and young people already have adaptations to manga, video games, animated series... Later, Spanish publishers will be encouraged and these will come to light thanks to great adapters and playwrights ranging from Valle-Inclán to Lorca, and many more later.With Realism and the Vanguards, more of the same thing will happen: due to the postwar period, this advance guard of reforming creators, mainly coming from France and Germany, will flood us with influences that will finally give us a slap in the face of existential boredom.
