I NEED THIS AS SOON AS POSSIBLE PLEASE! 50 POINTS! Please help me out which of the three periods you think was most important to world history. Your answer should describe the changes that took place during the period, as well as the short- and long-term effects on Europe and the rest of the world, and it should provide historical evidence supporting the period's importance. It should also include why the other two events are less important than the one you chose

In 336 B.C., Alexander the Great became the leader of the Greek kingdom of Macedonia. By the time he died 13 years later, Alexander had built an empire that stretched from Greece all the way to India. That brief but thorough empire-building campaign changed the world: It spread Greek ideas and culture from the Eastern Mediterranean to Asia. Historians call this era the “Hellenistic period.” (The word “Hellenistic” comes from the word Hellazein, which means “to speak Greek or identify with the Greeks.”) It lasted from the death of Alexander in 323 B.C. until 31 B.C., when Roman troops conquered the last of the territories that the Macedonian king had once ruled.

Macedonian Expansion

At the end of the classical period, around 360 B.C., the Greek city-states were weak and disorganized from two centuries of warfare. (First the Athenians fought with the Persians; then the Spartans fought with the Athenians during the Peloponnesian War; then the Spartans and the Athenians fought with one another and with the Thebans and the Persians.) All this fighting made it easy for another, previously unexceptional city-state to rise to power: Macedonia, under the assertive rule of King Philip II.

Did you know? Alexander the Great was just 20 years old when he became the leader of Macedonia.

Philip and the Macedonians began to expand their territory outward. They were helped along by a number of advances in military technology: long-range catapults, for example, along with pikes called sarissas that were about 16 feet long—long enough for soldiers to use not as projectiles, but as spears. King Philip’s generals also pioneered the use of the massive and intimidating infantry formation known as the phalanx.

King Philip’s ultimate goal was to conquer Persia and help himself to the empire’s land and riches. This was not to be; King Philip was assassinated by his bodyguard Pausanias in 336 B.C. at his daughter’s wedding, before he could enjoy the spoils of his victories. His son Alexander, known to history as "Alexander The Great," jumped at the chance to take over his father’s imperial project. The new Macedonian king led his troops across the Hellespont into Asia. (When he got there, he plunged an enormous sarissa into the ground and declared the land “spear won.”) From there, Alexander and his armies kept moving. They conquered huge chunks of western Asia and Egypt and pressed on into the Indus Valley.

The Hellenistic Age

Alexander’s empire was a fragile one, not destined to survive for long. After Alexander died in 323 B.C., his generals (known as the Diadochoi) divided his conquered lands amongst themselves. Soon, those fragments of the Alexandrian empire had become three powerful dynasties: the Seleucids of Syria and Persia, the Ptolemies of Egypt and the Antigonids of Greece and Macedonia.

Though these dynasties were not politically united–since Alexander’s death, they were no longer part of any Greek or Macedonian empire–they did share a great deal in common. It is these commonalities, the essential “Greek-ness” of the disparate parts of the Alexandrian world–that historians refer to when they talk about the Hellenistic Age.

The Hellenistic states were ruled absolutely by kings. (By contrast, the classical Greek city-states, or polei, had been governed democratically by their citizens.) These kings had a cosmopolitan view of the world, and were particularly interested in amassing as many of its riches as they could. As a result, they worked hard to cultivate commercial relationships throughout the Hellenistic world. They imported ivory, gold, ebony, pearls, cotton, spices and sugar (for medicine) from India; furs and iron from the Far East; wine from Syria and Chios; papyrus, linen and glass from Alexandria; olive oil from Athens; dates and prunes from Babylon and Damaskos; silver from Spain; copper from Cyprus; and tin from as far north as Cornwall and Brittany.

They also put their wealth on display for all to see, building elaborate palaces and commissioning art, sculptures and extravagant jewelry. They made huge donations to museums and zoos and they sponsored libraries (the famous

libraries at Alexandria and Pergamum, for instance) and universities. The university at Alexandria was home to the mathematicians Euclid, Apollonios and Archimedes, along with the inventors Ktesibios (the water clock) and Heron (the model steam engine).

Hellenistic Culture

People, like goods, moved fluidly around the Hellenistic kingdoms. Almost everyone in the former Alexandrian empire spoke and read the same language: koine, or “the common tongue,” a kind of colloquial Greek. Koine was a unifying cultural force: No matter where a person came from, he could communicate with anyone in this cosmopolitan Hellenistic world.

the process is called revolution because it was a process of great economic-social transformations that began in england in the xviii century.

the industrial mode of production spread throughout much of the northern hemisphere throughout the xix and early xx centuries.

the effect of this revolution was the distance between the countries, with respect to economic and political power.   after all, not all industrialized at the same time, remaining in the condition of suppliers of raw materials and agricultural products to the industrialized countries.

these differences mark to this day the nations of the world that are divided between developed and developing countries. one way to measure whether a country is advanced is to assess how industrialized it is.
