Lesson 3: Greece and Persia

In this Grade 4 lesson from Discovering Our Past: a History of the World, students explore how the Persian Empire expanded under rulers like Cyrus the Great and Darius I, learning key concepts such as satrapies, satraps, the Royal Road, and the religion of Zoroastrianism. The lesson then examines the military conflict between Persia and the Greek city-states, including the famous battles that shaped the ancient world. Part of Chapter 7 on Ancient Greece, it helps students understand why and how major civilizations came into conflict.

Section 1

Persian Kings Build the World's Largest Empire

Cyrus the Great and later Persian rulers conquered vast territories spanning 3,000 miles. King Darius organized the empire into satrapies, appointed satraps as governors, and built the Royal Road to connect regions.

Section 2

Zoroaster Transforms Persian Religious Beliefs

Zoroaster introduced monotheism to Persia through worship of Ahura Mazda, the supreme god of good. This religious shift led Persians to view their monarchy as sacred, with kings believing they ruled by divine power.

Section 3

Greeks Defeat Persian Forces at Marathon

In 490 BCE, 10,000 Athenian soldiers strategically attacked 20,000 Persians at Marathon while their cavalry boarded ships. After victory, a messenger ran 25 miles to Athens with news, inspiring today's marathon races.

Section 4

Greek Ships Outmaneuver Persian Fleet at Salamis

Themistocles lured Persian ships into the narrow strait of Salamis where their larger vessels became difficult to maneuver. Greek vessels, being smaller and faster, sank about 300 Persian ships while losing only 40.

Section 5

Persian Empire Weakens and Eventually Falls

Following defeats in Greece, Persia's military declined, unable to protect its vast territories. Heavy taxation for royal luxuries angered citizens, while family disputes over succession created instability, leading to conquest by Alexander.
