Its origin is not documented but its characteristics are unique. This is certainly the book identified in an inventory at the Great Mosque of Qairawan in 693AH (1294AD).
It originally contained about 600 pages of various sizes up to 31 x 41 cm. Many of them were scattered during the later Ottoman period and the last century. 67 remaining folios were transferred from Qairawan to Tunis in 1967.
The Blue Qur'an was probably executed in Andalusia or North Africa 1100 to 1000 years ago for a very powerful Islamic monarch who has not been identified. Its sumptuous indigo dye is considered as a successful attempt to surpass the luxury of Byzantine purple.
