1. The Threat of Macedonia and Alexander the Great

2. The Greeks viewed their northern neighbors, the Macedonians, as barbarians because they were rural people who did not live in city-states.
By the end of the 5th century B.C., Macedonia was a powerful kingdom.

3. In 359 B.C., Philip II became king of Macedonia.
He admired the Greek culture and wanted to unite all of Greece under Macedonian rule.
The Macedonian army crushed an army of Greek city-states at the Battle of Chaeronea in 338 B.C.
He insisted the Greek city-states form a league under his control and help him conquer Persia.
This did not happen because he was assassinated.

6. Alexander the Great became king at age 20.
He had been educated by the Greek philosopher Aristotle.
He considered non-Greeks the equal of Greeks and envisioned a world in which mixed cultures would live together.
He married 2 Persian princesses and encouraged his generals to marry Persian princesses.

7. His father had taught him military tactics and leadership.
Alexander moved quickly to fulfill his father’s dream of conquering Persia.
He wanted glory, empire, and revenge for the Persians burning Athens in 480B.C.
He entered Asia Minor in 334 B.C. with an army of 37,000 Macedonians and Greeks.

9. By 331 B.C. he had conquered the Persian Empire and established the city of Alexandria in Egypt.
He was not content. In 326 B.C., he crossed the Indus River and entered India. His soldiers refused to continue and went home.
Alexander died in 323 B.C.
His military success was due to his courage and a mastery of military tactics. He inspired his men to follow him.

10. The Hellenistic Kingdom
Alexander created a new age, called the Hellenistic Era.
The word Hellenistic means “to imitate Greeks.”
This era saw the expansion of the Greek language and ideas to the non-Greek world of Southwest Asia and beyond.

12. After Alexander’s death, his empire fell apart as Macedonian generals fought for power.
There were 4 Hellenistic kingdoms: Macedonia, Syria, Pergamum in western Asia Minor, and Egypt.
All were eventually conquered by Rome.
Unlike Alexander, these Hellenistic monarchs included only Greeks and Macedonians in their ruling class.—they did not want to share the political and social privileges with the Persians.

14. Hellenistic Culture
The Hellenistic Era saw considerable cultural achievements, especially in science and philosophy.
The most important cultural center was Alexandria, home to scholars of all kinds—philosophers, scientists, and writers.
Alexandria’s library was the largest of its kind, with over 500,000 scrolls.

15. Mathematics and Astronomy
Aristarchus developed the theory that the sun is the center of the universe and the earth rotates around it.
Eratosthenes determined that earth is round and nearly calculated the correct circumference of the earth.
Euclid wrote a textbook on plane geometry, the Elements, that was used up to modern times.
Archimedes established the value of pi and did important work in the geometry of spheres and cylinders.

16. Athens remained a center for philosophy.
It became the center of 2 new schools of thought, Epicureanism and Stoicism.
Epicurus believed that human beings were free to follow their self-interest. Happiness was the goal of life, and happiness was achieved by pursuing pleasure, the only true good.
Pleasure was not satisfying physical appetites but rather the freedom from anxiety that comes from a mind at rest.
Achieving this peace meant removing oneself from public life, but not social life.
Life could only be fulfilled when centered on virtuous friendship.

17. Stoicism Founded by a teacher named Zeno.
Emphasized achieving happiness.
Happiness was gained by living in harmony with the will of God.
Then life’s problems could not disturb a person
Stoics also regarded public service as noble and did not remove themselves from public life.
