Qin, Han, Tang and East Asia
In 221 BCE the Qin joined many kingdoms into one empire in China, with common weights, measures and writing. The Han (206 BCE to 220 CE) kept this state going. They chose officials for their skills and their loyalty, and they supported the teachings of Confucius, which stress duty, family and good government. The Han also opened the Silk Road to the west.
The Tang (618 to 907 CE) brought a new peak: a strong state, big cities and wide trade. China's writing, laws, Buddhism and city plans influenced Korea, Japan and Vietnam, which each adapted them in their own way. That shared inheritance is why we speak of an East Asian region.
Buddhism and Hinduism in South Asia
Buddhism began in northern India around the 5th century BCE with the teaching of the Buddha: life has suffering, desire causes it, and there is a path to end it. Emperor Ashoka (3rd century BCE) supported Buddhism, and monks and traders carried it across Central Asia to China, Korea, Japan and Southeast Asia.
Hinduism grew from many older traditions, texts and local beliefs. Over time, temples, devotion (bhakti), festivals and the idea of dharma shaped everyday life across the subcontinent, and Hindu ideas and art also reached Southeast Asia by sea. Monsoon winds made sea trade across the Indian Ocean regular and helped both religions travel.
Greece, Rome and West Asia
Greece was not one state but many independent city-states (poleis). Athens, in the 5th century BCE, tried a form of direct democracy for its male citizens. Greek thinkers asked questions in philosophy, science and drama. West Asia had older, large empires such as the Persian empire, which linked many peoples and roads.
Rome started as a city, became a republic (from about 509 BCE) and then an empire (from 27 BCE), ruling lands around the Mediterranean. Roman law, roads and the Latin language lasted for centuries. The sea was the highway: ships carried grain, wine, ideas and soldiers.
How the regions compare and connect
Each region had its own pattern: East Asia stands out for strong states and officials; South Asia for the growth and spread of religions; West Asia and the Mediterranean for city-states, empires, law and sea trade. But no region stood alone. The Silk Roads on land and the monsoon sea routes carried silk, spices, metals, religions and ideas between them.
Historians compare regions by asking: who ruled, how did people earn a living, what did they believe, and who did they trade with?
Try it: region detective
In the 3D: tap each region. Read the card, then close your eyes and say the landmark and the main idea. Then watch the purple dots: which routes link the three islands?
At home: make three cards, one per region, with a symbol and one word (Officials, Religions, Trade). Shuffle them and ask a friend to match symbol to region.
Key formulas and definitions
- Key term: dynasty = a family that rules for many generations
- Key term: city-state = a city that rules itself and its nearby land
- Key term: Silk Roads = trade routes across land linking East Asia with the west
- Key term: monsoon trade = sea trade that follows seasonal winds across the Indian Ocean
- Dates: Qin 221 BCE; Han 206 BCE to 220 CE; Tang 618 to 907 CE; Roman republic from about 509 BCE; Roman empire from 27 BCE
- Idea: states (East), religions (South), city-states and law (West), and routes link them all
Worked examples
1. How many years did the Han dynasty last, using 206 BCE to 220 CE?
From 206 BCE to 1 CE is 206 years, and from 1 CE to 220 CE is 220 years more. There is no year 0, so the total is about 206 + 220 - 1 = 425 years, and we say 'about 400 years'.
2. Why is East Asia called a region and not just 'China'?
Because Korea, Japan and Vietnam took ideas such as writing, laws and Buddhism from China but changed them in their own ways. They share a common inheritance, which makes a connected region.
3. How did Buddhism reach China from South Asia?
Monks and traders carried it along the Silk Roads through Central Asia, and later by sea. Over centuries the teaching, texts and art were adopted and adapted in China.
4. Give one way Greek city-states differed from the Roman empire.
Greek city-states were many small, separate self-governing cities, while Rome grew into a single large empire that ruled lands around the whole Mediterranean.
Common mistakes
- Thinking Greece was one country. It was many independent city-states.
- Mixing up Qin, Han and Tang dates. Order them: Qin (221 BCE), Han (206 BCE), Tang (618 CE).
- Saying Buddhism stayed only in India. It spread widely across Asia and was later less common in India.
- Treating regions as separate boxes. Trade routes and travelling ideas connected them.
