Western civilization describes the development of human civilization beginning in Ancient Greece, transforming in Ancient Rome, and spreading throughout Europe by evolving into Medieval Western Christendom.

The civilizations of Classical Greece (Hellenic) and Roman Empire (Latin) as well as Ancient Israel (Hebraism)Cambridge University Historical Series, An Essay on Western Civilization in Its Economic Aspects, p.40: Hebraism, like Hellenism, has been an all-important factor in the development of Western Civilization; Judaism, as the precursor of Christianity, has indirectly had had much to do with shaping the ideals and morality of western nations since the Christian era. and early Christendom are considered seminal periods in Western history.Caltron J.H Hayas, Christianity and Western Civilization (1953), Stanford University Press, p.2: That certain distinctive features of our Western civilization — the civilization of western Europe and of America— have been shaped chiefly by Judaeo–Graeco–Christianity, Catholic and Protestant.Horst Hutter, University of New York, Shaping the Future: Nietzsche's New Regime of the Soul And Its Ascetic Practices (2004), p.111:three mighty founders of Western culture, namely Socrates, Jesus, and Plato.Fred Reinhard Dallmayr, Dialogue Among Civilizations: Some Exemplary Voices (2004), p.22: Western civilization is also sometimes described as "Christian" or "Christian" civilization. From Ancient Greece sprang belief in democracy, and the pursuit of intellectual inquiry into such subjects as truth and beauty; from Rome came lessons in government administration, martial organization, engineering and law; and from Ancient Christianity with its ideals of the brotherhood of humanity. Strong cultural contributions also emerged from the pagan Germanic, Celtic, Finnic and Nordic peoples of pre-Christian Europe. Following the 5th-century "Fall of Rome", Europe entered the Middle Ages, during which period the Catholic Church filled the power vacuum left in the West by the fallen Roman Empire, while the Eastern Roman Empire (Byzantine Empire) endured for centuries.

Origins of the notion of "East" and "West"

The opposition of a European "West" to an Asiatic "East" has its roots in classical antiquity, with the Persian Wars, where the Greek city states (depicted as the west) were opposing the expansion of the Achaemenid Empire (depicted as the east). The Biblical opposition of Israel and Assyria from a European perspective was recast into these terms by early Christian authors such as Jerome, who compared it to the "barbarian" invasions of his own time (see also Assyria and Germany in Anglo-Israelism).

The "East" in the Hellenistic period was the Seleucid Empire, with Greek influence stretching as far as Bactria and India, besides Scythia in the Pontic steppe to the north. In this period, there was significant cultural contact between the Mediterranean and the East, giving rise to syncretisms like Greco-Buddhism. The establishment of the Byzantine Empire around the 4th century established a political division of Europe into East and West and laid the foundations for divergent cultural directions, confirmed centuries later with the Great Schism between Eastern Orthodox Christianity and Roman Catholic Christianity.

The Mediterranean and the Ancient West The earliest civilizations which influenced the development of the West were those of Mesopotamia, the area of the Tigris–Euphrates river system, largely corresponding to modern-day Iraq, northeastern Syria, southeastern Turkey and southwestern Iran: the cradle of civilization. An agricultural revolution began here around 10,000 years ago with the domestication of animals like sheep and goats and the appearance of new wheat hybrids, notably bread wheat, at the completion of the last Ice Age, which allowed for a transition from nomadism to village settlements and then cities like Jericho, Byblos and Damascus.Jacob Bronowski; The Ascent of Man; Angus & Robertson, 1973

The Sumerians, Akkadians, Babylonians, Assyrians and Canaanites all flourished in this region. Soon after the Sumerian civilization began, the Nile River valley of ancient Egypt was unified under the Pharaohs in the 4th millennium BC, and civilization quickly spread through the Fertile Crescent to the eastern coast of the Mediterranean Sea and throughout the Levant. The Phoenicians, Israelites and others later built important states in this region.

The ancient peoples of the Mediterranean heavily influenced the origins of Western civilisation. The Mediterranean Sea provided reliable shipping routes linking Asia, Africa and Europe along which political and religious ideas could be traded along with raw materials such as timber, copper, tin, gold and silver as well as agricultural produce and necessities such as wine, olive oil, grain and livestock. By 3100 BC, the Egyptians were employing sails on boats on the Nile River and the subsequent development of the technology, coupled with knowledge of the wind and stars allowed naval powers such as the Phoenicians, Greeks, Carthaginians and Romans to navigate long distances and control large areas by commanding the sea. Cargo galleys often also employed slave oarsmen to power their ships and slavery was an important feature of the ancient Western economy.Geoffrey Blainey; A Very Short History of the World; Penguin Books, 2004

Thus, the great ancient capitals were linked — cities such as: Athens, home to Athenian democracy, and the Greek philosophers Aristotle, Plato and Socrates; the city of Jerusalem, the Jewish capital, where Jesus of Nazareth preached and was executed around AD 30; and the city of Rome, which gave rise to the Roman Empire which encompassed much of Europe and the Mediterranean. Knowledge of Greek, Roman and Judeo-Christian influence on the development of Western civilization is well documented because it attached to literate cultures, however, Western history was also strongly influenced by less literate groups such as the Germanic, Scandinavian and Celtic peoples who lived in Western and Northern Europe beyond the borders of the Roman world. Nevertheless, the Mediterranean was the centre of power and creativity in the development of ancient Western civilisation. Around 1500 BC, metallurgists learned to smelt iron ore, and by around 800BC, iron tools and weapons were common along the Aegean Sea, representing a major advance for warfare, agriculture and crafts in Greece.

The earliest urban civilizations of Europe belong to the Bronze Age Minoans of Crete and Mycenaean Greece, which ended around the 11th century BC as Greece entered the Greek Dark Ages. Ancient Greece was the civilization belonging to the period of Greek history lasting from the Archaic period of the 8th to 6th centuries BC to 146 BC and the Roman conquest of Greece after the Battle of Corinth. Classical Greece flourished during the 5th to 4th centuries BC. Under Athenian leadership, Greece successfully repelled the military threat of Persian invasion at the battles of Marathon and Thermopylae. The Athenian Golden Age ended with the defeat of Athens at the hands of Sparta in the Peloponnesian War in 404 BC.

By the 6th century BC, Greek colonists had spread far and wide — from the Russian Black Sea coast to the Spanish Mediterranean and through modern Italy, North Africa, Crete, Cyprus and Turkey. The Ancient Olympic Games are said to have begun in 776 BC and grew to be a major cultural event for the citizens of the Greek diaspora, who met every four years to compete in such sporting events as running, throwing, wrestling and chariot driving. Trade flourished and by 670 BC the barter economy was being replaced by a money economy, with Greeks minting coins in such places as the island of Aegina. Poultry arrived from India around 600 BC and would grow to be a European staple. The Hippocratic Oath, historically taken by doctors swearing to practice medicine ethically, is said to have been written by the Greek Hippocrates, often regarded as the father of western medicine, in Ionic Greek (late 5th century BC),The Hippocratic oath: text, translation and interpretation By Ludwig Edelstein Page 56 (1943)

The Greek city states competed and warred with each other, with Athens rising to be the most impressive. Learning from the Egyptians, Athenian art and architecture shone from 520 to 420 BC and the city completed the Parthenon around 447 BC to house a statue of their city goddess Athena. The Athenians also experimented with democracy. Property owners assembled almost weekly to make speeches and instruct their temporary rulers: a council of 500, chosen by lot or lottery, whose members could only serve a total of 2 years in a lifetime, and a smaller, high council from whom one man was selected by lottery to preside from sunset to the following sunset.

Thus, the citizens' assembly shared power and prevented lifetime rulers from taking control. Military chiefs were exempt from the short term requirement however and were elected, rather than chosen by lot. Eloquent oratory became a Greek art form as speakers sought to sway large crowds of voters. Athenians believed in 'democracy' but not in equality and excluded women, slaves, the poor and foreigners from the assembly. Notions of a general "brotherhood of man" were yet to emerge.

Ancient Greek philosophy arose in the 6th century BC and continued through the Hellenistic period, at which point Ancient Greece was incorporated into the Roman Empire. It dealt with a wide variety of subjects, including political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric, and aesthetics. Plato was a Classical Greek philosopher, mathematician and writer of philosophical dialogues. He was the founder of the Academy in Athens which was the first institution of higher learning in the Western world. Inspired by the admonition of his mentor, Socrates, prior to his unjust execution that "the unexamined life is not worth living", Plato and his student, the political scientist Aristotle, helped lay the foundations of Western philosophy and science. Plato's sophistication as a writer is evident in his Socratic dialogues.

In classical tradition, Homer is the ancient Greek epic poet, author of the Iliad, the Odyssey and other works. Homer's epics stand at the beginning of the western canon of literature, exerting enormous influence on the history of fiction and literature in general.

Alexander the Great (356 BC-323 BC) was a Greek king of Macedon and the creator of one of the largest empires in ancient history. He was tutored by the philosopher Aristotle and, as ruler, broke the power of Persia, overthrew the Persian king Darius III and conquered the Persian Empire. His Macedonian Empire stretched from the Adriatic Sea to the Indus River. He died in Babylon in 323 BC and his empire did not long survive his death. Nevertheless, the settlement of Greek colonists around the region had long lasting consequences and Alexander features prominently in Western history and mythology.Yenne, W.

The city of Alexandria in Egypt, which bears his name and was founded in 330 BC, became the successor to Athens as the intellectual cradle of the Western World. The city hosted such leading lights as the mathematician Euclid and anatomist Herophilus; constructed the great Library of Alexandria; and translated the Hebrew Bible into Greek (called the Septuagint for it was the work of 70 translators).
