In past centuries, the Transumanza had a great impact on the lives of the shepherds whose job was made more difficult by the lack of modern agricultural machinery, enclosed pens for grazing, and refrigeration of the sheep's milk that was gathered along the way. Economic concerns were established at the grazing sites, these dealing with the production and sale of cheese, sheepskins, and wool. Much of the work was carried out by men with women remaining behind in Abruzzo. The well-worn paths along which the sheep traveled during their migrations were referred to as "tratturi". The three main pathways included those between L'Aquila and Foggia (called "The King's pathway"), Celano and Foggia, and Pescasseroli and Candela ("The wool pathway").[1] The migrations many times lasted up to two weeks with stops at locations known as "stazioni di posta" (post stations).
In earlier times, sheep migrations similar to the transumanza were also conducted in Spain and the Balkan states. The custom was at its peak in the fifteenth century following the population losses in the area due to the Black Plague.
