A Doll's House is an 1879 play by Norwegian playwright Henrik Ibsen. Written one year after The Pillars of Society, the play was the first of Ibsen's to create a sensation and is now perhaps his most famous play, and required reading in many secondary schools and universities. The play was controversial when first published, as it is sharply critical of 19th century marriage norms.
It follows the formula of well-made play up until the final act, when it breaks convention by ending with a discussion, not an unravelling. It is often called the first true feminist play. The play is also an important work of the naturalist movement, in which real events and situations are depicted on stage in a departure from previous forms such as romanticism. - Wikipedia
