the agricultural and industrial revolutions of northern Europe. The above-mentioned study by Denis Mack Smith is confirmed by the Italian historian and left wing politician Antonio Gramsci in his book "The Southern Question", by which the author emphasizes the "absolutely antithetical conditions" of Northern and Southern Italy at the time of Italian unification in 1861, when South and North were united again after more than one thousand years. Gramsci remarks that, in the North of Italy, the historical period of the Comunes had given a special boost to history and in Northern Italy existed an economic organization similar to that of the other states of Europe, propitious to further development of capitalism and industry, whereas in Southern Italy history had been different and the fatherly Bourbon administrations produced nothing of value; the bourgeois class did not exist, agriculture was primitive and insufficient to satisfy the local market, there were no roads, no ports, the few waterways that the region had were not exploited, due to its special geographical features. The living conditions of the people of the Kingdom of the Two Sicilies are also illustrated by Raffaele De Cesare, who reports that the king of Naples Ferdinand II had no interest in doing useful works to improve the neglected condition of public hygiene, particularly in the provinces where scarcity of sewer systems and often water shortages were known issues. The problem of brigandage is explained in the book Heroes and Brigands by the southern Italian historian and politician Francesco Saverio Nitti, outlining that brigandage was endemic in Southern Italy, since the Bourbons themselves relied on it as their military agent. Unlike Southern Italy, there was little brigandage in the other annexed states of northern and central Italy, like the Kingdom of Lombardy–Venetia, the Duchy of Parma, the Duchy of Modena, the Grand Duchy of Tuscany and the Papal States. According to the southern Italian historian Giustino Fortunato, and Italian institutional sources the problems of Southern Italy existed way before Italian unification, and Giustino Fortunato emphasizes that the Bourbons were not the only ones responsible for the problems of the South, which had ancient and deep origins also in previous centuries of poverty and isolation, caused by foreign domination and foreign governments. In literature, the period of 1860 was depicted by Sicilian writer Giuseppe Tomasi di Lampedusa in his famous novel Il Gattopardo (The Leopard), set in Sicily at the time
