Leone Caetani

His father Onorato Caetani, Prince of Teano and Duke of Sermoneta, was Italian Minister of Foreign Affairs in 1896 in the second di Rudini cabinet; his English mother, Ada Bootle Wilbraham, was the daughter of the Earl of Lathom.

Caetani spent many years researching and traveling throughout the Muslim world, gathering material on a wide range of Islamic cultures from Tunisia, Algeria, Egypt, Syria, Turkey, Iraq, the Levant, the Sahara, India, Central Asia, and southern Russia.

After the end of his marriage[3] and the rise of Fascism, in August 1921 Caetani decided to emigrate to Vernon, British Columbia, Canada, with his new partner Ofelia Fabiani and their daughter Sveva.

In 1935, the Fascist regime stripped him of his Italian citizenship and expelled him from the Accademia dei Lincei; he died of throat cancer on December 24, 1935 in Vancouver, British Columbia.

Caetani presented his critical analysis and conclusions regarding what he believed to be inconsistencies, contradictions, and variances in the Islamic sources in his ten-volume work Annali dell'Islam.
