Terra di Lavoro (Liburia in Latin) is the name of a historical region of Southern Italy. It corresponds roughy to the modern southern Lazio and northern Campania and upper north west and west border area of Molise regions of Italy.
In Italian the name means literally "Land of Work", but in fact derives from the ancient Liburia, a territory north of Aversa which took its name from the ancient tribe of the Leborini.
The Terra di Lavoro was originally a giustizierato (justiciarship) and then a province of the Kingdom of Sicily, later Kingdom of Naples. After the Congress of Vienna (1815) it became a department of the Kingdom of the Two Sicilies, and, after the unification of Italy (1860s), a province of the Regno d'Italia. The capital was Capua until 1818 and then Caserta.
In the pre-Republican Italy, the Terra di Lavoro was one of the largest provinces: it comprised the current province of Caserta, the southern part of today's provinces of Latina and Frosinone, the countryside of Nola of the province of Naples, and the Sannio (provinces of Benevento, Campobasso and Isernia).
