Ali Bey al Abbasi

Domingo Francisco Jorge Bada y Leblich , better known by his pseudonym and nom de plume Ali Bey el Abbassi , was a Spanish explorer, soldier, and spy in the early 19th century. He supported the French occupation of Spain and worked for the Bonapartist administration, but he is principally known for his travels in North Africa and the Middle East. He witnessed the Saudi conquest of Mecca in 1807.

Bada y Leblich was born in Barcelona on April 1, 1767. After receiving a liberal education, he devoted particular attention to the Arabic language, which he learned in Vera, Almera, where his father was a military accountant, and in London. He also made a special study of the manners and customs of Arabian lands.
