New Beginnings: Cities and States
Class 7 Social Science Chapter 4 | Complete NCERT Guide | Second Urbanisation, Janapadas Mahajanapadas, Governance
Full Chapter Summary & Detailed Notes – New Beginnings: Cities and States
Opening Quote – Kautilya (Arthashāstra)
“The kingdom shall be protected by fortifying the capital and the towns at the frontiers… It should be beautiful, being endowed with cultivable land, mines, timber forests, elephant forests, and good pastures rich in cattle… It should have good roads and waterways. It should have a productive economy, with a wide variety of commodities…”
This quote shows the idea of an ideal kingdom in ancient India – strong, rich, and self-sufficient.

The Big Questions (3 Questions – Very Important)
- What is meant by ‘Second Urbanisation of India’?
- Why were the janapadas and mahājanapadas an important development in India’s early history?
- What kind of system of governance did they evolve?
Second Urbanisation of India (~600 BCE)
After the decline of the Indus Valley Civilisation (First Urbanisation), cities disappeared). Around 600 BCE, cities re-emerged in the Ganga-Yamuna valley – called Second Urbanisation.
Reasons:
- Use of iron tools → better farming → surplus food
- Surplus food → population growth → trade → towns and cities
- New materials: baked bricks, iron weapons, coins
- Cities: Pataliputra, Ujjain, Taxila, Vaishali, Rajagriha
Janapadas → Mahājanapadas
| Stage | Meaning | Features |
|---|---|---|
| Janapada | “Jana” (people) + “pada” (foot) = land where people settled | Small territories, tribal chiefs, villages |
| Mahājanapada | “Great janapada” | 16 large, powerful states around 600 BCE |
Most Powerful Mahājanapadas: Magadha, Kosala, Vatsa, Avanti
Why Were Mahājanapadas Important?
- First real states in India
- Fixed boundaries, capital cities, standing armies
- Tax collection started
- Trade and craft grew
- Beginning of cities and urban life
Two Types of Government
| Type | Ruled By | Examples |
|---|---|---|
| Monarchy (Rajya) | King (Raja) – hereditary | Magadha (Bimbisara, Ajatashatru), Kosala |
| Gana or Sangha (Republic) | Assembly of people (no single king) | Vajji (Lichchhavis), Shakya (Buddha’s clan) |
Features of Mahājanapadas
- Fortified capital cities (e.g., Rajagriha had huge walls)
- Standing armies (soldiers paid salary)
- Tax system: farmers paid 1/6th of produce (Bhaga)
- Craftsmen, traders, merchants became important
- Use of coins (punch-marked coins) started
Magadha – The Most Powerful Mahājanapada
Reasons for Rise:
- Fertile land (Ganga plain)
- Iron mines nearby
- Elephants for army
- Good location for trade
- Strong rulers: Bimbisara, Ajatashatru
Key Takeaways for Exams
- Second Urbanisation = cities re-emerged after Indus Valley (~600 BCE)
- 16 Mahājanapadas – Magadha most powerful
- Two governments: Monarchy (king) & Gana (assembly)
- Kautilya’s Arthashāstra = book on ideal kingdom
