Jacob Burckhardt in the context of "Kulturgeschichte"

The Italian Renaissance (Italian: Rinascimento [rinaʃʃiˈmento]) was a period in Italian history during the 15th and 16th centuries. The period and place are known for the initial development of the broader Renaissance culture that spread from Italy to the rest of Europe (and also to extra-European territories ruled by colonial powers or where Christian missionaries and/or traders were active). The period was one of transition: it sits between the Middle Ages and the modern era. Proponents of a "long Renaissance" argue that it started around the year 1300 and lasted until about 1600. In some fields, a Proto-Renaissance, beginning around 1250, is typically accepted. The French word renaissance (corresponding to rinascimento in Italian) means 'rebirth', and defines the period as one of cultural revival and renewed interest in classical antiquity after the centuries during what Renaissance humanists labelled as the "Dark Ages". The Italian Renaissance historian Giorgio Vasari used the term rinascita ('rebirth') in his Lives of the Most Excellent Painters, Sculptors, and Architects in 1550, but the concept became widespread only in the 19th century, after the work of scholars such as Jules Michelet and Jacob Burckhardt.

The Renaissance began in Tuscany in Central Italy and centered in the city of Florence. The Florentine Republic, one of the several city-states of the peninsula, rose to economic and political prominence by providing credit to European monarchs and by laying the groundwork for developments in capitalism and banking. Renaissance culture later spread to Venice, the heart of a Mediterranean empire controlling trade routes with the east since its participation in the Crusades and following the journeys of Marco Polo between 1271 and 1295. Thus Italy renewed contact with the remains of ancient Greek culture, which provided humanist scholars with new texts. Finally the Renaissance had a significant effect on the Papal States and on Rome, largely rebuilt by humanist and Renaissance popes, such as Julius II and Leo X, who frequently became involved in Italian politics, in arbitrating disputes between competing colonial powers and in opposing the Protestant Reformation, which started c. 1517.

Cleanliness is both the state of being clean and free from germs, dirt, trash, or waste, and the habit of achieving and maintaining that state. Cleanliness is often achieved through cleaning. In most cultures, cleanliness is considered a good quality, as indicated by the aphorism: "Cleanliness is next to Godliness", and may be regarded as contributing to other ideals such as health and beauty.

The concept of cleanliness emphasizes an ongoing procedure or set of habits for the purpose of maintenance and prevention. In this it differs from purity, which is a physical, moral, or ritual state of freedom from pollutants. Whereas purity is usually a quality of an individual or substance, cleanliness has a social dimension. "Cleanliness", observed Jacob Burckhardt, "is indispensable to our modern notion of social perfection". A household or workplace may be said to exhibit cleanliness, but ordinarily not purity. Cleanliness is also a characteristic of people who maintain cleanness or prevent dirtying.

The Civilization of the Renaissance in Italy (German: Die Cultur der Renaissance in Italien) is an 1860 work on the Italian Renaissance by Swiss historian Jacob Burckhardt. Together with his History of the Renaissance in Italy (Die Geschichte der Renaissance in Italien; 1867) it is counted among the classics of Renaissance historiography. An English translation was produced by S.G.C. Middlemore in two volumes, London 1878.

Erik Maria Ritter von Kuehnelt-Leddihn (31 July 1909 – 26 May 1999) was an Austrian-American nobleman and polymath, whose areas of interest included philosophy, history, political science, economics, linguistics, art and theology. He opposed the ideas of the French Revolution, as well as those of communism and Nazism. Describing himself as a "conservative arch-liberal" or "extreme liberal", Kuehnelt-Leddihn often argued that majority rule in democracies is a threat to individual liberties. He declared himself a monarchist and an enemy of all forms of totalitarianism, although he also supported what he defined as "non-democratic republics", such as Switzerland and the early United States. Kuehnelt-Leddihn cited the U.S. Founding Fathers, Tocqueville, Burckhardt, and Montalembert as the primary influences for his skepticism towards democracy.

Described as a "Walking Book of Knowledge" by William F. Buckley Jr., Kuehnelt-Leddihn had an encyclopedic knowledge of humanities and was a polyglot, being able to speak eight languages and read seventeen others. His early books The Menace of the Herd (1943) and Liberty or Equality (1952) were influential within the American conservative movement. An associate of Buckley Jr., his best-known writings appeared in National Review, where he was a columnist for 35 years.
