5. Haryanka Dynasty: The Foundation

👑 Bimbisara (544-492 BC) - The Real Founder

Matrimonial Alliances:
• Married Kausala Devi (sister of Koshal King Prasenjit) → Got Kashi in dowry.
• Married Chellana (daughter of Lichchhavi King Chetaka).
• Married Khema (daughter of Madra King).
Diplomacy: Sent royal physician Jivaka to treat Avanti King Pradyota.
Contemporary of Buddha: Buddha's first sermon at Rajgriha. Donated Veluvana Monastery.
Death: Killed by his son Ajatashatru (Patricide).

⚔️ Ajatashatru (492-460 BC) - The Imperialist

Wars:
• Fought with Koshal (initially lost, then ally after marrying Vajira).
• 16-year war with Vajji Confederacy (used Rathamusala & Mahashilakantaka - war machines).
Fortification: Built fort at Pataligrama (later Pataliputra).
Buddhist Council: 1st Buddhist Council at Rajgriha (483 BC) after Buddha's death.
Death: Killed by his son Udayin.

🏛️ Udayin (460-444 BC)

Capital Shift: Moved capital from Rajgriha to Pataliputra (at Ganga-Son confluence).
Built fort at Pataliputra.
Pataliputra remained capital for Nanda & Maurya dynasties too.

6. Nanda Dynasty (344-321 BC)

Founder: Mahapadma Nanda (Shudra origin - revolutionary!).
Title: "Ekarat" (Only Sovereign), "Sarvakshatrantaka" (Destroyer of all Kshatriyas).
9 Nanda Kings: Mahapadma + 8 sons (including Dhana Nanda).
Military Power: Huge army (mentioned in Greek sources).
Hathigumpha Inscription: Mahapadma Nanda dug canal in Kalinga (1st canal mention!).
Downfall: Heavy taxation + extortion → Public discontent → Overthrown by Chandragupta Maurya.

                💡 Why Nandas Failed?

                1. Over-taxation (even on small items)

                2. Autocratic rule

                3. No public support

                → Chanakya + Chandragupta exploited this weakness!

7. Pataliputra: The Imperial Capital

Founded by: Udayin (Haryanka).
Location: Confluence of Ganga & Son river (modern Patna).
Strategic Importance: Trade route hub, fertile land, river transport.
Continued as capital for: Shishunaga → Nanda → Maurya → Gupta dynasties.
Buddhist Councils: 3rd Council by Ashoka (247 BC), 1st Jain Council here.
Greek Account: Megasthenes described its prosperity in "Indica".
