Lesson 6: Alexander the Great and His Empire

In this Grade 6 lesson from History Alive! The Ancient World, students explore how Alexander the Great built his vast empire following the Peloponnesian War and the rise of Macedonia under Philip II. Students learn how Alexander used a strategy of terror and kindness to expand Macedonian rule from Greece through Central Asia and into western India, and how his tutelage under Aristotle shaped his leadership. The lesson also examines the challenges of uniting diverse peoples and cultures across such a large empire.

Section 1

Alexander Blends Cultures to Rule an Empire

Key Idea

Alexander the Great used his powerful army to conquer a vast empire stretching from Greece to India. He then faced the challenge of ruling over many different groups of people.

To unite his empire, Alexander used more than just force. He spread Greek ideas by founding new cities and showed respect for local ways of life by adopting Persian customs.

Section 2

Disease Changes History

Key Idea

Widespread diseases have often changed the course of history. During the Peloponnesian War, the Plague of Athens struck the crowded city-state. The deadly sickness spread rapidly among the population.

The plague killed thousands, including Athens's leader, Pericles. The loss of so many people and a key leader severely weakened the city. This disruption helped its rival, Sparta, eventually win the war.

Section 3

Cultures Mix and Clash in Alexander's Empire

Key Idea

After Alexander’s conquests, Greek soldiers, traders, and leaders moved into new lands across Asia and Africa. They brought their language, art, and ideas with them, spreading Greek culture in a process called Hellenism.

Many local peoples blended Greek ways with their own traditions. This cultural fusion created new styles of art, new beliefs, and new cities. For example, some gods were seen as both Greek and Egyptian.

Section 4

Hellenistic Culture Sparks Innovation

Key Idea

After Alexander’s conquests, new cities became centers for Greek culture and learning. The city of Alexandria in Egypt was the most famous. It had a great library and museum, attracting scholars and thinkers from all over the known world.

During this Hellenistic Period, these scholars made amazing scientific advancements in math, medicine, and astronomy. Art also changed, with sculptures showing more realistic emotions instead of just perfect forms. Religions blended as people combined Greek gods with their own local beliefs.
