Josep Capdeferro is a Legal Historian specialised in the Early Modern period (16th-18th centuries). He is associate professor at Universitat Pompeu Fabra (Barcelona). Most of his works are based on archival research.

He deals with a wide range of topics: Jurists; legal sources; legal culture; rule of law; judicial records; representative institutions; parliamentarism; local governments; accountability; minorities; discriminations; women; guilds; conflicts of jurisdictions.

Some of his recent works focus on a singular court called "Tribunal de Contrafaccions" (early 18th century), the punishment that adulteress women received in Barcelona at the "Casa de les Egipcíaques" (15th-18th centuries), parliamentary dynamics (parliamentary committees) and institutional accountability.
