The Renaissance is an interval in European history, covering the length between the 14th and 17th centuries. It is an extension of the Middle Ages, and is bridged from the Age of Enlightenment into contemporary history. It grew in fragments, with the very first traces discovered seemingly in Italy, coming to pay much of Europe, for some scholars marking the start of the contemporary era.
The intellectual basis of the Renaissance was its invented version of humanism, based on the idea of Roman Humanitas along with the rediscovery of classical Greek philosophy, like that of Protagoras, who stated that “Man is the measure of everything.” This fresh thinking has been manifest in art, architecture, politics, literature, and science. Early examples were the development of perspective in oil painting along with the recycled understanding of how to make concrete. Even though the creation of movable metal type sped the dissemination of thoughts from the later 15th century, the changes of the Renaissance were not uniformly experienced across Europe.
As a cultural movement, the Renaissance surrounded innovative flowering of Latin and vernacular literature, beginning with the 14th-century resurgence of studying based on ancient resources, which contemporaries credited to Petrarch; the development of linear perspective and other techniques of producing a more natural fact in painting; and slow but prevalent educational reform. In politics, the Renaissance led to the development of the customs and conventions of diplomacy, also in science into a heightened reliance on observation and inductive reasoning. Even though the Renaissance saw revolutions in many intellectual pursuits, in addition to political and social upheaval, it’s perhaps best known for its artistic developments along with the gifts of such polymaths as Leonardo da Vinci and Michelangelo, who inspired the term “Renaissance man”.
The Renaissance began in Florence, in the 14th century. A variety of theories have been suggested to account for its roots and characteristics, focusing on a variety of factors such as the social and civic peculiarities of Florence in the time: its political structure; the patronage of its dominant family, the Medici; and also the migration of Greek scholars and texts into Italy following the Fall of Constantinople into the Ottoman Turks.  Other major centers were northern Italian city-states such as Venice, Genoa, Milan, Bologna, and eventually Rome throughout the Renaissance Papacy.
The Renaissance has quite a lengthy and complex historiography, and, in accord with general scepticism of discrete periodizations, there has been much disagreement among historians responding to the 19th-century glorification of the “Renaissance” and individual culture heroes as “Renaissance men”, questioning the usefulness of Renaissance for a term and as a historical delineation. The art historian Erwin Panofsky discovered of the resistance to the Idea of “Renaissance”:
