One Thousand and One Nights (Arabic: أَلْفُ لَيْلَةٍ وَلَيْلَةٌ, Alf Laylah wa-Laylah) is a collection of Middle Eastern folktales compiled in the Arabic language during the Islamic Golden Age. It is often known in English as The Arabian Nights, from the first English-language edition (c. 1706–1721), which rendered the title as The Arabian Nights' Entertainments.
The work was collected over many centuries by various authors, translators, and scholars across West Asia, Central Asia, South Asia, and North Africa. Some tales trace their roots back to ancient and medieval Arabic, Persian, and Mesopotamian literature. Most tales, however, were originally folk stories from the Abbasid and Mamluk eras, while others, especially the frame story, are probably drawn from the Pahlavi Persian work Hezār Afsān (Persian: هزار افسان, lit. 'A Thousand Tales'), which in turn relied partly on Indian elements.
