"Early Modern period is a term used by historians to refer to the period between the Middle Ages (Post-classical era) and the Industrial Revolution – roughly 1500 to 1800. The Early Modern period is characterized by the rise of science, and by increasingly rapid technological progress, secularized civic politics, and the nation-state. Capitalist economies began their rise, initially in northern Italian republics such as Genoa. The Early Modern period also saw the rise and dominance of the mercantilist economic theory. As such, the Early Modern period represents the decline and eventual disappearance, in much of the European sphere, of feudalism, serfdom and the power of the Catholic Church. The period includes the late decades of the Protestant Reformation, the disastrous Thirty Years' War, the Age of Discovery, European colonial expansion, and the peak of European witch-hunting.
Renaissance
Europe's Renaissance, beginning in the 14th century, consisted of the rediscovery of the classical world's scientific contributions, and of the economic and social rise of Europe. The Renaissance also engendered a culture of inquisitiveness which ultimately led to Humanism and the Scientific Revolution. Although it saw social and political upheaval and revolutions in many intellectual pursuits, the Renaissance is perhaps known best for its artistic developments and the contributions of such polymaths as Leonardo da Vinci and Michelangelo, who inspired the term "Renaissance man".
This era in European culture also saw the 16th-century Protestant Reformation and the 17th-century Age of Enlightenment, which led to the Scientific Revolution.

Movable-type printing press arose in mid-15th century. 50 years later, nine million books were in print.
During this period, European powers came to dominate most of the world. The most developed regions of classical civilization were more urbanized than any other region of the world until early modern times. This civilization had, however, gradually declined and collapsed; historians still debate the causes.
Regional developments
Persia came under the rule of the Safavid Empire in 1501, succeeded by the Afsharid Empire in 1736, and the Qajar Empire in 1796. Areas to the north and east were held by Uzbeks and Pashtuns. The Ottoman Empire, after taking Constantinople in 1453, quickly gained control of the Middle East, the Balkans, and most of North Africa.
The Pacific islands of Oceania would also be affected by European contact, starting with the circumnavigational voyage of Ferdinand Magellan, who landed on the Marianas and other islands in 1521. Also notable were the voyages (1642–44) of Abel Tasman to present-day Australia, New Zealand and nearby islands, and the voyages (1768-1779) of Captain James Cook, who made the first recorded European contact with Hawaii. Britain would found its first colony on Australia in 1788.
Civilization
A civilization (US) is any complex society characterized by urban development, social stratification, symbolic communication forms (typically, writing systems), and a perceived separation from and domination over the natural environment by a cultural elite. Civilizations are intimately associated with and often further defined by other socio-politico-economic characteristics, including centralization, the domestication of both humans and other organisms, specialization of labor, culturally ingrained ideologies of progress and supremacism, monumental architecture, taxation, societal dependence upon farming as an agricultural practice, and expansionism.
How Was Earth Formed?
Thereare two theories as to how planets in the solar system were created. The first and most widely accepted, core accretion, works well with the formation of the terrestrial planets like Earth but has problems with giant planets. The second, the disk instability method, may account for the creation of giant planets. Scientists are continuing to study planets in and out of the solar system in an effort to better understand which of these methods is most accurate.
The core accretion model
Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
With the rise of the sun, the remaining material began to clump up. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create smaller terrestrial worlds like Earth. But farther away, the solar winds had less impact on lighter elements, allowing them to coalesce into gas giants. In this way, asteroids, comets, planets, and moons were created.
Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter pieces created the crust. The planet's magnetic field probably formed around this time. Gravity captured some of the lighter elements that make up the planet's early atmosphere.
Early in its evolution, Earth suffered an impact by a large body that catapulted pieces of the young planet's mantle into space. Gravity caused many of these pieces to draw together and form the moon, which took up orbit around its creator.
The flow of the mantle beneath the crust causes plate tectonics, the movement of the large plates of rock on the surface of the Earth. collisions and friction gave rise to mountains and volcanoes, which began to spew gases into the atmosphere.
Although the population of comets and asteroids passing through the inner solar system is sparse today, they were more abundant when the planets and sun were young. Collisions from these icy bodies likely deposited much of the Earth's water on its surface. Because the planet is in the Goldilocks zone, the region where liquid water neither freezes nor evaporates bur can remain as a liquid, the water remained at the surface, which many feel plays a key role in the development of life.
The disk instability model
Although the core accretion model works fine for terrestrial planets, gas giants would have needed to evolve rapidly to grab hold of the significant mass of lighter gases they contain. But simulations have not been able to account for this rapid formation. According to models, the process takes several million years, longer than the light gases were available in the early solar system. At the same time, the core accretion model faces a migration issue, as the baby planets are likely to spiral into the sun in a short amount of time.
According to a relatively new theory, disk instability, clumps of dust and gas are bound together early in the life of the solar system. Over time, these clumps slowly compact into a giant planet. These planets can form faster than their core accretion rivals, sometimes in as little as a thousand years, allowing them to trap the rapidly-vanishing lighter gases. They also quickly reach an orbit-stabilizing mass that keeps them from death-marching into the sun.
As scientists continue to study planets inside of the solar system, as well as around other stars, they will better understand how Earth and its siblings formed.
The term "prehistory" can refer to the vast span of time since the beginning of the Universe or the Earth, but more often it refers to the period since life appeared on Earth, or even more specifically to the time since human-like beings appeared.[2][3]
End
The date marking the end of prehistory in a particular culture or region, that is, the date when relevant written historical records become a useful academic resource, varies enormously from region to region. For example, in Egypt it is generally accepted that prehistory ended around 3200 BC, whereas in New Guinea the end of the prehistoric era is set much more recently, at around 1900 AD. In Europe the relatively well-documented classical cultures of Ancient Greece and Ancient Rome had neighbouring cultures, including the Celts and to a lesser extent the Etruscans, with little or no writing, and historians must decide how much weight to give to the often highly prejudiced accounts of these "prehistoric" cultures in Greek and Roman literature.
Time periods
In dividing up human prehistory, historians typically use the three-age system, whereas scholars of pre-human time periods typically use the well-defined geologic record and its internationally defined stratum base within the geologic time scale. The three-age system is the periodization of human prehistory into three consecutive time periods, named for their respective predominant tool-making technologies:
