In The Wahhabis seen through European Eyes (1772-1830) Giovanni Bonacina offers an account of the early reactions in Europe to the rise of the Wahhabi movement in Arabia. Commonly pictured nowadays as a form of Muslim fundamentalism, the Wahhabis appeared to many European witnesses as the creators of a deistic revolution with serious political consequences for the Ottoman ancien regime. They were seen either in the light of contemporary events in France, or as Islamic theological reformers in the mould of Calvin, opposing an established church and devotional traditions. These audacious but fascinating attempts to interpret the unknown by way of the better known are illustrated in Bonacina’s book.
