Social and political structures in Italy
The unique political structures of late Middle Ages Italy have led some to theorize that its unusual social climate allowed the emergence of a rare cultural efflorescence. Italy did not exist as a political entity in the early modern period. Instead, it was divided into smaller city states and territories: the Kingdom of Naples controlled the south, the Republic of Florence and the Papal States at the center, the Milanese and the Genoese to the north and west respectively, and the Venetians to the east. Fifteenth-century Italy was one of the most urbanised areas in Europe. Many of its cities stood among the ruins of ancient Roman buildings; it seems likely that the classical nature of the Renaissance was linked to its origin in the Roman Empire's heartland.
Historian and political philosopher Quentin Skinner points out that Otto of Freising (c. 1114–1158), a German bishop visiting north Italy during the 12th century, noticed a widespread new form of political and social organization, observing that Italy appeared to have exited from Feudalism so that its society was based on merchants and commerce. Linked to this was anti-monarchical thinking, represented in the famous early Renaissance fresco cycle Allegory of Good and Bad Government in Siena by Ambrogio Lorenzetti (painted 1338–1340), whose strong message is about the virtues of fairness, justice, republicanism and good administration. Holding both Church and Empire at bay, these city republics were devoted to notions of liberty. Skinner reports that there were many defences of liberty such as the Matteo Palmieri (1406–1475) celebration of Florentine genius not only in art, sculpture and architecture, but "the remarkable efflorescence of moral, social and political philosophy that occurred in Florence at the same time".
Even cities and states beyond central Italy, such as the Republic of Florence at this time, were also notable for their merchant Republics, especially the Republic of Venice. Although in practice these were oligarchical, and bore little resemblance to a modern democracy, they did have democratic features and were responsive states, with forms of participation in governance and belief in liberty. The relative political freedom they afforded was conducive to academic and artistic advancement. Likewise, the position of Italian cities such as Venice as great trading centres made them intellectual crossroads. Merchants brought with them ideas from far corners of the globe, particularly the Levant. Venice was Europe's gateway to trade with the East, and a producer of fine glass, while Florence was a capital of textiles. The wealth such business brought to Italy meant large public and private artistic projects could be commissioned and individuals had more leisure time for study.
Black Death/Plague
One theory that has been advanced is that the devastation in Florence caused by the Black Death, which hit Europe between 1348 and 1350, resulted in a shift in the world view of people in 14th-century Italy. Italy was particularly badly hit by the plague, and it has been speculated that the resulting familiarity with death caused thinkers to dwell more on their lives on Earth, rather than on spirituality and the afterlife. It has also been argued that the Black Death prompted a new wave of piety, manifested in the sponsorship of religious works of art. However, this does not fully explain why the Renaissance occurred specifically in Italy in the 14th century. The Black Death was a pandemic that affected all of Europe in the ways described, not only Italy. The Renaissance's emergence in Italy was most likely the result of the complex interaction of the above factors.
The plague was carried by fleas on sailing vessels returning from the ports of Asia, spreading quickly due to lack of proper sanitation: the population of England, then about 4.2 million, lost 1.4 million people to the bubonic plague. Florence's population was nearly halved in the year 1347. As a result of the decimation in the populace the value of the working class increased, and commoners came to enjoy more freedom. To answer the increased need for labor, workers traveled in search of the most favorable position economically.
The demographic decline due to the plague had economic consequences: the prices of food dropped and land values declined by 30 to 40% in most parts of Europe between 1350 and 1400. Landholders faced a great loss, but for ordinary men and women it was a windfall. The survivors of the plague found not only that the prices of food were cheaper but also that lands were more abundant, and many of them inherited property from their dead relatives.
The spread of disease was significantly more rampant in areas of poverty. Epidemics ravaged cities, particularly children. Plagues were easily spread by lice, unsanitary drinking water, armies, or by poor sanitation. Children were hit the hardest because many diseases such as typhus and syphilis target the immune system and left young children without a fighting chance. Children in city dwellings were more affected by the spread of disease than the children of the wealthy.
The Black Death caused greater upheaval to Florence's social and political structure than later epidemics. Despite a significant number of deaths among members of the ruling classes, the government of Florence continued to function during this period. Formal meetings of elected representatives were suspended during the height of the epidemic due to the chaotic conditions in the city, but a small group of officials was appointed to conduct the affairs of the city, which ensured continuity of government.
