This is a scarce example of J. Arrowsmith's 1842 map of southern Italy. It covers the Kingdom if Naples (a common reference for the 'Kingdom of the Two Sicilies'), which extended from the Papal States south to include all of Sicily. The Maltese Islands are featured in an inset in the lower right quadrant. As this map was being prepared, the peninsula was undergoing its Risorgimento, Italy's march toward national solidarity. Following the defeat of Napoleon and the merging of Sicily and Naples into the Two Sicilies, the Island of Sicily witnessed revolts against the Bourbon rule in 1820 and 1848. The final revolution in 1848 would result in the island gaining independence from Bourbon control for 16 months. The Kingdom of Naples was the richest and largest Italian state before the Italian unification.The map notes numerous cities, towns, rivers, roads and topography with relief shown by hachures. The map was published by J. Arrowsmith in 1842.
