Shut-a your face! (FemRomano App)

Prehistory and antiquity
In the 8th and 7th centuries BCE, for various reasons, including demographic crisis (famine, overcrowding, etc.), the search for new commercial outlets and ports, and expulsion from their homeland, Greeks began to settle in Southern Italy (Cerchiai, pp. 14–18). Also during this period, Greek colonies were established in places as widely separated as the eastern coast of the Black Sea, Eastern Libya and Massalia (Marseille). They included settlements in Sicily and the southern part of the Italian Peninsula. The Romans called the area of Sicily and the foot of Italy, Magna Graecia (Latin, "Great Greece"), since it was so densely inhabited by the Greeks. The ancient geographers differed on whether the term included Sicily or merely Apulia and Calabria—Strabo being the most prominent advocate of the wider definitions.
With this colonisation, Greek culture was exported to Italy, in its dialects of the Ancient Greek language, its religious rites and its traditions of the independent polis. An original Hellenic civilization soon developed, later interacting with the native Italic and Latin civilisations. The most important cultural transplant was the Chalcidean/Cumaean variety of the Greek alphabet, which was adopted by the Etruscans; the Old Italic alphabet subsequently evolved into the Latin alphabet, which became the most widely used alphabet in the world.
Many of the new Hellenic cities became very rich and powerful, like Neapolis (Νεάπολις, Naples, "New City"), Syracuse, Acragas, and Sybaris (Σύβαρις). Other cities in Magna Graecia included Tarentum (Τάρας), Epizephyrian Locri (Λοκροί Ἐπιζεφύριοι), Rhegium (Ῥήγιον), Croton (Κρότων), Thurii (Θούριοι), Elea (Ἐλέα), Nola (Νῶλα), Syessa (Σύεσσα), Bari (Βάριον), and others.
After Pyrrhus of Epirus failed in his attempt to stop the spread of Roman hegemony in 282 BCE, the south fell under Roman domination and remained in such a position well into the barbarian invasions (the Gladiator War is a notable suspension of imperial control). It was held by the Byzantine Empire after the fall of Rome in the West and even the Lombards failed to consolidate it, though the centre of the south was theirs from Zotto's conquest in the final quarter of the 6th century.

Middle Ages
Following the Gothic War (535–554), and until the arrival of the Normans, much of Southern Italy's destiny was linked to the fortunes of the Eastern Empire, even though Byzantine domination was challenged in the 9th century by the Lombards, who annexed the area of Cosenza to their Duchy of Benevento. Consequently, the Lombard and the Byzantine areas became influenced by Eastern monasticism and much of Southern Italy experienced a slow process of orientalisation in religious life (rites, cults and liturgy), which accompanied a spread of Eastern churches and monasteries that preserved and transmitted the Greek and Hellenistic tradition (the Cattolica monastery in Stilo is the most representative of these Byzantine monuments). From then to the Norman conquest of the 11th century, the south of the peninsula was constantly plunged into wars between Greece, Lombardy, and the Islamic Caliphate. The latter established several Islamic states in southern Italy, such as the Emirate of Sicily and Emirate of Bari. Amalfi, an independent republic from the 7th century until 1075, and to a lesser extent Gaeta, Molfetta and Trani, rivalled other Italian maritime republics in their domestic prosperity and maritime importance.
In the 11th century, the Normans occupied all the Lombard and Byzantine possessions in Southern Italy, ending the six centuries old presence of both powers in the peninsula, and eventually expelled the Muslims from Sicily. The Norman Kingdom of Sicily under Roger II was characterised by its competent governance, multi-ethnic nature and religious tolerance. Normans, Jews, Muslim Arabs, Byzantine Greeks, Lombards and "native" Sicilians lived in relative harmony. However, the Norman domination lasted only several decades before it formally ended in 1198 with the reign of Constance of Sicily, and was replaced by that of the Swabian Hohenstaufen dynasty.
In Sicily, Emperor Frederick II endorsed a deep reform of the laws culminating with the promulgation of the Constitutions of Melfi (1231, also known as Liber Augustalis), a collection of laws for his realm that was remarkable for its time and was a source of inspiration for a long time after. It made the Kingdom of Sicily a centralised state and established the primacy of written law. With relatively small modifications, the Liber Augustalis remained the basis of Sicilian law until 1819. His royal court in Palermo, from around 1220 to his death, saw the first use of a literary form of an Italo-Romance language, Sicilian, that had a significant influence on what was to become the modern Italian language. During this period, he also built the Castel del Monte, and in 1224, he founded the University of Naples, now called, after him, Università Federico II.
In 1266, conflict between the Hohenstaufen house and the Papacy led to Sicily's conquest by Charles I, Duke of Anjou. Opposition to French officialdom and taxation combined with incitement of rebellion by agents from the Byzantine Empire and the Crown of Aragon led to the Sicilian Vespers insurrection and successful invasion by king Peter III of Aragon in 1282. The resulting War of the Sicilian Vespers lasted until the Peace of Caltabellotta in 1302, dividing the old Kingdom of Sicily in two. The island of Sicily, called the "Kingdom of Sicily beyond the Lighthouse" or the Kingdom of Trinacria, went to Frederick III of the house of Aragon, who had been ruling it. The peninsular territories, contemporaneously called Kingdom of Sicily, but called Kingdom of Naples by modern scholarship, went to Charles II of the House of Anjou, who had likewise been ruling it. Thus, the peace was formal recognition of an uneasy status quo. Despite the king of Spain being able to seize both the two crowns starting from the 16th century, the administrations of the two halves of the Kingdom of Sicily remained separated until 1816, when they were reunited in the Kingdom of Two Sicilies.

Early modern history
In 1442, however, Alfonso V conquered the Kingdom of Naples and unified Sicily and Naples once again as dependencies of the Crown of Aragon. At his death in 1458, the kingdom was again separated and Naples was inherited by Ferrante, Alfonso's illegitimate son. When Ferrante died in 1494, Charles VIII of France invaded Italy, using the Angevin claim to the throne of Naples, which his father had inherited on the death of King René's nephew in 1481, as a pretext, thus beginning the Italian Wars. Charles VIII expelled Alfonso II of Naples from Naples in 1495, but was soon forced to withdraw due to the support of Ferdinand II of Aragon for his cousin, Alfonso II's son Ferrantino. Ferrantino was restored to the throne, but died in 1496, and was succeeded by his uncle, Frederick IV. The French, however, did not give up their claim, and in 1501 agreed to a partition of the kingdom with Ferdinand of Aragon, who abandoned his cousin King Frederick. The deal soon fell through, however, and the Crown of Aragon and France resumed their war over the kingdom, ultimately resulting in an Aragonese victory leaving Ferdinand in control of the kingdom by 1504.
The kingdom continued to be a focus of dispute between France and Spain for the next several decades, but French efforts to gain control of it became feebler as the decades went on, and Spanish control was never genuinely endangered. The French finally abandoned their claims to the kingdom by the Treaty of Cateau-Cambrésis in 1559. With the Treaty of London (1557) the new client state of "Stato dei Presidi" (State of Presidi) was established and governed directly by Spain, as part of the Kingdom of Naples.
After the War of the Spanish Succession in the early 18th century, possession of the kingdom again changed hands. Under the terms of the Treaty of Utrecht in 1713, Naples was given to Charles VI, the Holy Roman Emperor. He also gained control of Sicily in 1720, but Austrian rule did not last long. Both Naples and Sicily were conquered by a Spanish army during the War of the Polish Succession in 1734, and Charles, Duke of Parma, a younger son of King Philip V of Spain was installed as King of Naples and Sicily from 1735. When Charles inherited the Spanish throne from his older half-brother in 1759, he left Naples and Sicily to his younger son, Ferdinand IV. Despite the two kingdoms being in a personal union under the House of Bourbon from 1735 onwards, they remained constitutionally separated.

Early 19th century
Being a member of the House of Bourbon, King Ferdinand IV was a natural opponent of the French Revolution and Napoleon. In January 1799, Napoleon Bonaparte, in the name of the French Republic, captured Naples and proclaimed the Parthenopaean Republic, a French client state, as successor to the kingdom. King Ferdinand fled from Naples to Sicily until June of that year. In 1806, Bonaparte, by then French Emperor, again dethroned King Ferdinand and appointed his brother, Joseph Bonaparte, as King of Naples. In the Edict of Bayonne of 1808, Napoleon removed Joseph to Spain and appointed his brother-in-law, Joachim Murat, as King of the Two Sicilies, though this meant control only of the mainland portion of the kingdom. Throughout this Napoleonic interruption, King Ferdinand remained in Sicily, with Palermo as his capital.
After Napoleon's defeat, King Ferdinand IV was restored by the Congress of Vienna of 1815 as Ferdinand I of the Two Sicilies. He established a concordat with the Papal States, which previously had a claim to the land. There were several rebellions on the island of Sicily against the King Ferdinand II but the end of the kingdom was only brought about by the Expedition of the Thousand in 1860, led by Garibaldi, an icon of the Italian unification, with the support of the House of Savoy and their Kingdom of Sardinia. The expedition resulted in a striking series of defeats for the Sicilian armies against the growing troops of Garibaldi. After the capture of Palermo and Sicily, he disembarked in Calabria and moved towards Naples, while in the meantime the Piedmontese also invaded the Kingdom from the Marche. The last battles fought were that of the Volturnus in 1860 and the siege of Gaeta, where King Francis II had sought shelter, hoping for French help, which never came. The last towns to resist Garibaldi's expedition were Messina (which capitulated on 13 March 1861) and Civitella del Tronto (which capitulated on 20 March 1861). The Kingdom of the Two Sicilies was dissolved and annexed to the new Kingdom of Italy, founded in the same year.

Southern and Northern Italy in 1860
At the time of the Italian Unification, the gap between Northern and Southern Italy was great, in the Northern states of Italy existed roads for about 75,500 kilometers, railroads for 2,316 kilometers and a wide range of channels connected to rivers for goods transportation, iron and steel production was 17,000 tons per year, on the contrary in the Southern Kingdom of the Two Sicilies existed only 14,700 kilometers of roads, 184 kilometers of railroads (only near Naples), no channels connected to rivers and iron and steel production was only 1,500 tons per year.
Illiteracy in the Italian peninsula of 1860 had an average of 75%, the lowest peak of 54% was in Northern West the Kingdom of Sardinia or Piedmont, increasing moving to South, where in the Kingdom of the Two Sicilies illiteracy reached the highest peak of 87%.
In 1860 the southern merchant navy amounted to 260,000 tons, whereas the northern merchant navy 347,000 tons, aside from the Venetian navy annexed in 1866 and assessed 46,000 tons. In 1860 the whole Italian merchant navy was the fourth of Europe with about 607,000 tons. The Southern merchant navy was made up of sailing vessels mainly for fishing and coastal shipping in the Mediterranean Sea and it had very few steamships, even if one of the first steamers was built and fitted in Naples in 1818. Both merchant and military navy were insufficient compared to the great coastal extent of Southern Italy defined by the Italian historian Raffaele De Cesare: "… a great pier towards South".
In addition to the merchant navy we must also consider the waterway network connected with rivers and canals, which was used to transport goods in a large area, the waterway network was highly developed in the north and nonexistent in the south.
Denis Mack Smith, British historian, describes the radical difference between Northern and Southern Italy in 1860, for these two halves were on quite different levels of civilization, pointing out that in the Kingdom of the Two Sicilies the Bourbon were staunch supporters of a feudal system and that they had feared the traffic of ideas and had tried to keep their subjects insulated from the agricultural and industrial revolutions of northern Europe.
In the Kingdom of the Two Sicilies roads were scanty or nonexistent and passports necessary even for internal travel, in fact most southerners lived in squalor, afflicted by drought, malaria and earthquakes and for many years after 1860 a peasant from Calabria had little in common with one from Piedmont, whose former capital Turin was infinitely more like Paris and London than Naples and Palermo.
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 the Italian Unification in 1861, when South and North united themselves again after more than one thousand years.
Gramsci remarks that, in the North of Italy, the historical period of the Communes had given 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 administrations of Spain and of the Bourbons had created nothing, bourgeoisie did not exist, agriculture was primitive and insufficient to satisfy the local market, no roads, no ports, no exploitation of the few waters that the region had, due to its special geographical feature.
Life conditions of the people of the Kingdom of the Two Sicilies are illustrated also by Raffaele De Cesare, who reports the lack of interest from the king of Naples Ferdinand II to do useful works to change the neglected conditions of public hygiene, particularly in the provinces where existed scarsity of sewer systems and often water shortage.
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, where for centuries monarchy based itself on Brigandage, that had become like a historical agent. Unlike Southern Italy, Brigandage was generally little in the other annexed states of northern and central Italy like: Kingdom of Lombardy-Venetia, Duchy of Parma, Duchy of Modena, Grand Duchy of Tuscany, Papal States, because the situation of Southern Italy was very different, owing to the previous centuries of history.
According to the southern Italian historian Giustino Fortunato, and Italian institutional sources the problems of Southern Italy existed before the Italian Unification, in this regard Giustino Fortunato underlines that the Bourbon were not the only ones responsible for southern problems, that had ancient and deep origins also in previous centuries of poverty and isolation, caused by foreign dominations and governments.
In literature the period of 1860 is described by the Sicilian writer Giuseppe Tomasi di Lampedusa in his famous novel The Leopard (Il Gattopardo) set in Sicily during the years of the Italian unification, in a famous final scene prince Salina, when invited to join the senate of unified Italy, answers to an important Piedmontese officer " … the Sicilian will never want to change, because the Sicilian feels perfect …", by which and by other words the author underlines the problem for the Sicilians to change their old life style while remaining in their island. The novel was represented in the homonymous film The Leopard (1963 film) by Luchino Visconti in which the actor Burt Lancaster played as Prince Salina.

After 1861
The southern economy greatly suffered after the Italian unification and the process of industrialisation was interrupted. Poverty and organised crime though were persistent problems in Southern Italy as well and it got worse after unification. Cavour decided the basic problem was poor government, and believed that could be remedied by strict application of the Piedmonese legal system. The main result was an upsurge in brigandage. Because of this, the South experienced great economic difficulties resulting in massive emigration leading to a worldwide Italian diaspora, especially to the United States and South America. Many natives also relocated to the industrial cities in northern Italy, such as Genoa, Milan and Turin. A relative process of industrialisation has developed in some areas of the "Mezzogiorno" after World War II. In the 1946 referendum after the war, the region voted to keep the monarchy, with its greatest support coming in Campania. Politically, it is often at odds with northern Italy, which won the referendum to establish a republic. Today, the South remains less economically developed than the north and central regions, which enjoyed an "economic miracle" in the 1950s and 1960s and became highly industrialized.
