However, the long wars against the Longobards weakened the region. With the Donation of Sutri in 728, the Bishop of Rome acquired the first territory in the region beyond the Duchy of Rome. The strengthening of the religious and ecclesiastical aristocracy led to continuous power struggles between secular lords ("Baroni") and the Pope until the middle of the 16th century. Innocent III tried to strengthen his own territorial power, wishing to assert his authority in the provincial administrations of Tuscia, Campagna and Marittima through the Church's representatives, in order to reduce the power of the Colonna family. Other popes tried to do the same. During the period when the papacy resided in Avignon, France (1309–1377), the feudal lords' power increased due to the absence of the Pope from Rome. Small communes, and Rome above all, opposed the lords' increasing power, and with Cola di Rienzo, they tried to present themselves as antagonists of the ecclesiastical power. However, between 1353 and 1367, the papacy regained control of Lazio and the rest of the Papal States. From the middle of the 16th century, the papacy politically unified Lazio with the Papal States, so that these territories became provincial administrations of St. Peter's estate; governors in Viterbo, in Marittima and Campagna, and in Frosinone administered them for the papacy. Lazio comprised the short-lived Roman Republic, in which it became a puppet state of the First French Republic under the forces of Napoleon Bonaparte. The Republic existed from 15 February 1798 until Lazio was returned to the Papal States in October 1799. In 1809, Lazio was annexed to the French Empire under the name of Department of Tibre, but returned under the Pope in 1815. On 20 September 1870 the capture of Rome, during the reign of Pope Pius IX, and France's defeat at Sedan, completed Italian unification, and Lazio was incorporated into the Kingdom of Italy. In 1927 the territory of the Province of Rieti, belonging to Umbria and Abruzzo, joined Lazio. Towns in Lazio were devastated by the 2016 Central Italy earthquake which occurred on 24 August 2016. Agriculture, crafts, animal husbandry and fishery are the main traditional sources of income. Agriculture is characterized by the cultivation of wine grapes, fruit, vegetables and olives. Industrial development in Lazio is limited to the areas south of Rome.
