as Paul of Tarsus who actively encouraged the founding of Christian communities or "churches" after his conversion.

Christianity spread initially from Jerusalem throughout the Near East. In the 4th century it was successively adopted as the state religion by Armenia in 301, Ethiopia in 325, Georgia in 337, and then the Roman Empire in 380. It became common to all of Europe in the Middle Ages and expanded throughout the world during Europe's Age of Exploration from the Renaissance onwards to become the world's largest religion.[1]

As this anticommunist hysteria spread throughout the 1950s, liberal college professors lost their jobs, people were asked to testify against colleagues and "loyalty oaths" became commonplace.

. The Bay of Pigs invasion in 1961 and the Cuban missile crisis the following year seemed to prove that the real communist threat now lay in the unstable, postcolonial "Third World" Nowhere was this more apparent than in Vietnam, where the collapse of the French colonial regime had led to a struggle between the American-backed nationalist Ngo Dinh Diem in the south and the communist nationalist Ho Chi Minh in the north.

Cold War heated up again under President Ronald Reagan (1911-2004). Like many leaders of his generation, Reagan believed that the spread of communism anywhere threatened freedom everywher

nstead of viewing the world as a hostile, "bi-polar" place, he suggested, why not use diplomacy instead of military action to create more poles? To that end, he encouraged the United Nations to recognize the communist Chinese government and, after a trip there in 1972, began to establish diplomatic relations with Beijing. At the same time, he adopted a policy of "détente"–"relaxation"–toward the Soviet Union. In 1972, he and Soviet premier Leonid Brezhnev (1906-1982) signed the Strategic Arms Limitation Treaty (SALT I), which prohibited the manufacture of nuclear missiles by both sides and took a step toward reducing the decades-old threat of nuclear war.

the Berlin Wall–the most visible symbol of the decades-long Cold War–was finally destroyed, just over two years after Reagan had challenged the Soviet premier in a speech at Brandenburg Gate in Berlin: "Mr. Gorbachev, tear down this wall." By 1991, the Soviet Union itself had fallen apart. The Cold War was over.

Greek scupture inspired the Romans and (indirectly) the great sculptors of the Renaissance.

Elements of Greek architecture have been copied again and again from Roman times onward--and we still see many elements of Greek architecture in at least some of our public buildings today.

Sports (Olympic games)

The Greeks also are important for the contribution to sports.

There are lots of other echoes of the Greeks in our sports tradition of today.

  History (first and some of greatest historians, including HERODOTUS, Thucydides, and Xenophon)

The Greeks give us the first true historical works, and it was a Greek (Herodotus) that first used the term "history" for what we call history today.  Not only did the Greeks give us our first historical works, they also give us some of  our greatest.

The buildings on the Athenian acropolis are a great example.

First of all, it is impressive because it moves beyond the mere chronicling of events (something that had been done before) and attempts to explain why certain events happen and what those events means: what lesssons we can learn from history.

  Herodotus might be considered, not just the father of history, but the father of cultural anthropology as well.

And particular this is so when one looks at Herodotus' central theme: freedom.  A central theme of Herodotus' book is the value of living in a free society (even though it means sacrifice) rather than living under despotism no matter how well-organized and prosperous a society run by a despot might seem.  Herodotus book is one of the sources of the Western love of freedom.

Political science Not only do the Greeks give us our first history, they give us also our first political science, the systematic study of human government.  When one studies political science today, one constantly uses Greek terms (monarchy, democracy, etc.). Why?  Because the Greeks were the first to study the various forms of human government and to identify the strengths and weakness of each.

Aristotle's Politics and Plato's Republic are still much read in political science/political philosophy classes today, another good example of the lasting influence of the Greeks.

Poetry In poetery too, the Greek had a lasting influence.  When we analyze poetry today, we use Greek words (iamb, dactyl, trochee, etc.).  Why?  Because the Greeks were the first to systematically analyze poetry.  Here too Aristotle is a key figure.  His "Poetics" is as influential in literary criticism as his "Politics" is in political science.

Among the greatest and most influential of epic poems are the two great poems of Homer, the Iliad and the Odyssey. 

The Greeks also excelled at lyric poetry. 

Mathematics Math is another area in which the Greeks made important contributions.  You are all familiar with the Pythagorean theorum, and the Greek reverence for numbers that starts with Pythagoras is certainly an important contribution of the Greeks.

Now what's important here is *not* the practical application of geometry.  What's important is the systematic, rigorous thinking process one must go through in coming up with these proofs.  The study of Euclid taught generation after generation to think clearly and logically: and it is a pity that the current geometry texts have drifted away from this.

  Science The Greeks also made important contributions to the sciences.  Biology, Physics, Physiology, Zoology: all Greek names, because the Greeks were the first to systematically explore these areas.  Thales, the first Greek philosopher, also is the father of physics, asking a fundamental question: what are all things made of?  The Greeks explored the question, coming up with promising answers.  Ultimately, Greeks like Aristotle believed that the world was made up of four fundamental elements. Other Greeks added the idea that these elements in their turn were made up of invisible, indivisable particles they called atoms.  Now we have a lot more elements than the Greek four, and we believe the atom can be divided into evern more fundamental particles, but note that the Greeks are certainly on the right track.

Perhaps most impressive of all was Archimedes

  But its not just in literature the Greeks excelled. They produced some of the world's greatest art, the first true science, and some of the greatest athletes the world has ever seen.  In fact, of all the ancient peoples, it was the Greeks who contributed the most to subsequent civilization in virtually every field of human endeavor.  What's all the more amazing is that the Greek were able to do all these things despite the fact that they were constantly at war--or maybe because they were constantly at war. Generalization: Greeks made more important contributions to sub. civilization than any other ancient people.  Achievements:

fueled by the arms race and the growing threat of nuclear weapons, wide-ranging espionage and counter-espionage between the two countries, war in Korea and a clash of words and ideas carried out in the media.

In 1959, the Soviet space program took another step forward with the launch of Luna 2, the first space probe to hit the moon

In April 1961, the Soviet cosmonaut Yuri Gagarin became the first person to orbit Earth, traveling in the capsule-like spacecraft Vostok 1. For the U.S. effort to send a man into space, dubbed Project Mercury, NASA engineers designed a smaller, cone-shaped capsule far lighter than Vostok; they tested the craft with chimpanzees, and held a final test flight in March 1961 before the Soviets were able to pull ahead with Gagarin's launch. On May 5, astronaut Alan Shepard became the first American in space (though not in orbit).

Later that May, President John F. Kennedy made the bold, public claim that the U.S. would land a man on the moon before the end of the decade. In February 1962, John Glenn became the first American to orbit Earth, and by the end of that year, the foundations of NASA's lunar landing program--dubbed Project Apollo--were in place.
