The twelfth-century legal compilation known as the Usatges de Barcelona holds an important place in the history of Catalonia. Recognized as authoritative by kings and parliaments alike from at least the thirteenth century, the Usatges were integrated into the official collection of Catalan law commissioned by the Corts and the new king of Aragón, Fernando de Antequera, in 1412–13. The work of the jurists who carried out this task was eventually fixed in print (in Catalan) in 1495 as the Constitutions y altres drets de Cathalunya, which was reissued in 1588–89 and again in 1704. The Usatges thus formed part of the law of the region for over 500 years, until the suppression of Catalan local law in the Decreto de Nueva Planta of 1716; thereafter, they survived — and still survive — as a focus of Catalan nationalism and regional pride. For medieval historians, the Usatges usefully supplement Catalonia's abundant documentary evidence, evidence unaccompanied before the thirteenth century by significant narrative sources. Individual articles cover such diverse topics as composition payments for injuries, guidelines for judicial proceedings, inheritance rules, military obligation, the status of Jews and Muslims, marriage, rape, treason, and public highways. Drawn from and influenced by a wide variety of sources — including the Visigothic code, Roman law, comital charters, and royal decrees — they provide valuable information about legal traditions and reasoning in Catalonia.
